Process Orders (PP-PI-POR)

Process Orders (PP-PI-POR) Purpose Process orders are the main element used for the detailed planning and execution of process manufacturing.

A process order describes the production of batches (materials) in a production run or the rendering of services. It is generated from the master recipe and contains all the information specified during process planning.

You use a process order to plan the quantities, dates, and resources of the manufacturing process, to control process order execution, and to define rules for the account assignment and settlement of the costs incurred.

In PP-PI, process orders perform the same function as production orders in PP.

Implementation Considerations Install this component in process manufacturing companies.

Integration If you want to Then you must install the component

Plan material usage during the process Material Master (LO-MD)

Plan how the resources are to be used during the process

Resources (PP-PI-MD)

Plan the external processing of steps in the process Purchasing (MM-PUR)

Plan quality inspections during production Quality Planning (QM-PT)

Provide data for process control Process Management (PP-PI-PMA)

Prepare cost determination using the master recipe Controlling

Features This component comprises all functions for order processing [Page 13] and order closing [Page 15].

Process Order

Process Order Definition Manufacturing order used in process industries.

Use Process orders are used for the production of materials or for rendering of services in a specific quantity on a specific date. They enable the planning of resources, control of process order management, and specify the rules for account assignment and order settlement.

Structure A process order consists of operations, each of which is carried out at a primary resource. An operation is subdivided into phases.

A phase is an independent process step that contains the detailed description of a part of the entire manufacturing process. Phases are carried out at the primary resource of their superior operation.

The way phases are related to each other specifies the sequence of the manufacturing process. Phase relationships can be sequential, parallel, or overlapping.

Several materials required for the execution of a specific process step can be planned for an operation or phase.

A phase contains standard values for activities. These values serve to calculate dates, capacity requirements, and costs.

Several secondary resources can be planned for operations and phases in addition to the primary resource.

A phase contains a number of process instructions that convey information relevant to process control.

Integration A process order can be based on a master recipe [Ext.].

A process order can be created from a planned order.

During order processing, the process instructions of a phase are transferred to the control recipe destination that requires the information for process control.

An inspection lot for inspection during production can be created when a process order is released.

A production process is triggered by existing production requirements. During material requirements planning, production requirements are converted into planned orders defining the planned basic dates and production quantities.

During process planning, planned orders are converted into process orders. The basic dates and production quantities are copied from the planned order. The actual production dates are calculated using the basic dates. You can also create a process order manually.

A process order provides a detailed description of the actual production of one or more materials in one production run.

A master recipe is used as the basis for a process order. It defines, for example, the planned resources and material components.

After a process order has been released for production, the process instructions maintained in the order are bundled into control recipes during process management. The control recipes are either transferred to a process control system via a specific interface or they are displayed in natural language in the form of a process instruction sheet (PI sheet) which can be maintained by the line operator.

In return, process management receives process messages from the process control level and transfers them to different destinations. For instance, it is possible to record actual values of the process to functions for process data documentation and evaluation, post material consumptions or production yields as goods movements, and transfer quality data to results recording of Quality Management.

Process planning comprises all activities that are performed during the creation and release of a process order. Important steps in process planning are:

Order creation Scheduling Capacity requirements planning Material availability check Order release

The release of the process order represents the end of process planning and is the prerequisite for carrying out the business functions for process order execution and process management.

In process management the process instructions maintained in the order are bundled into control recipes. The control recipes are either transferred to a process control system via a specific interface or they are displayed in natural language in the form of a PI sheet which can be maintained by the line operator.

Process order execution comprises:

Withdrawal of required material components from the warehouse

Process Order Management

Confirmations on the order processing status In-process quality inspections for the inspection lot Goods receipt from production Sending of actual process data to different destinations using process messages, for

example for documentation or evaluation purposes

In PP-PI, the activities of order execution are carried out using process messages. In return to the transfer of control recipes, process management receives process messages from the process control level and passes them on to different destinations.

Order closing comprises the following activities:

Process order settlement Process data documentation Reorganization of process orders (archiving and deleting)

Order Processing

Order Processing Order processing comprises the central processing steps involved in the life cycle of a process order.

Process planning comprising

Process order creation Selecting a master recipe Creating reservations or copying them from planned orders Calculating planned costs Creating capacity requirements for the resources

Scheduling Starting with the basic order dates, the system automatically schedules the process order when you create it. In addition, it can later be rescheduled automatically or manually whenever changes relevant to scheduling have been made.

Release of process order

Process order execution and process management

Creating and downloading control recipes (optional) Printing shop floor documents Carrying out material withdrawals

Withdrawing material components required in the manufacturing process in the form of goods issues from the warehouse.

Recording confirmations Carrying out in-process quality inspections (optional) Posting goods receipts

Delivering the manufactured product to the warehouse by posting a goods receipt.

You only create control recipes during process order execution if you want to use PI sheets and/or process control systems. In this case, you must also select the corresponding components from Process Management.

If you also want to carry out in-process quality inspections for your orders, you must select the relevant components from Quality Management.

14 April 2001


Order Closing

Order Closing Order closing comprises the following steps carried out at the end of the life cycle of a process order:

Process order settlement Archiving of process orders

To be able to settle a process order, you must choose the special functions for process manufacturing within Product Cost Controlling.

April 2001 15


Creating Process Orders

Creating Process Orders Use You can create process orders in the following ways:

As a rule, process orders are created when planned orders [Ext.] are converted in requirements planning. This process is the same as when you create a process order manually with a reference to a material. Certain data is already specified in the planned order (material, quantity, basic dates, possibly the master recipe, ). A distinction is made between the following:

Collective conversion [Page 41] (n planned orders n process orders) Individual conversion [Page 43] (1 planned order 1 process order) Partial conversion [Page 44] (1 planned order n process orders)

You can also create a process order manually: With reference to a material and master recipe [Page 18] With reference to a material but without a master recipe [Page 35] With an approved master recipe [Page 38] Without reference to a material but using a master recipe [Page 37] With a reference. Here you can select an object by choosing Continue (settlement rule,

operations, material, relationships, process instructions) or by entering a sales order.

Features When a planned order is converted to a process order

The material to be produced, the order quantity, and the order dates are copied from the planned order

The secondary requirements of the components are converted to reservations A planning file entry is generated when changing the requirement quantity or basic dates

from the planned order, which triggers a regenerative planning of the material and its components during the next requirements planning run.

When a planned order is partially converted to a process order

The partially converted planned order is fixed, which means it is not changed again in a requirements planning run. Its secondary requirements are reduced in accordance with the converted partial quantity

The planned order still exists until the Delete planned order indicator is set: This occurs automatically as soon as the planned order quantity is completely covered

by process orders

You can set it if you do not want to convert the planned order anymore (independent of the planned order quantity that is still open).

16 April 2001



The production version that is valid for the original planned order quantity is always used if the master recipe selection for the process order to be created is controlled by a production version.

When a process order is actually created (manually or by conversion)

A master recipe - even an approved one, if required - is usually selected (see Automatic Master Recipe Selection [Page 26]) and serves as the reference for the process order. The operation, phase, and resource data are copied from it, as well as the components in the material list.

Automatic batch creation [Page 29] is possible for the material to be produced.

April 2001 17


Creating Process Orders With Material & Master Recipe

Creating Process Orders With Material & Master Recipe 1. Choose Logistics Production - process Process order and then Process order

Create With material. The Create Process Order: Initial Screen appears.

2. Enter the following data:

The material number of the material in your master recipe; Automatic batch creation [Page 29] can be carried out for the material you want to produce.

The plant in which the material is to be produced (production plant)

The plant in which the goods receipt takes place for the material produced (planning plant). You must only make an entry here if the planning plant is different to the production plant.

The process order type (this controls, for example, whether an internal or external number range is to be used) If you enter an order type that requires internal number assignment, the system automatically assigns a number when you save the process order.

If you have selected an order type that requires external number assignment, you must also enter an order number in the Process order field.

3. Choose Continue.

The Create Process Order: Header - General Data screen appears.

4. Enter the following data:

Total qty: Here, you specify the quantity you want to produce. The unit of measure you specified in the material master record is used. If you want to base your process order on a master recipe, make sure that the total quantity you enter in this screen is within the material quantity range specified in your master recipe. Otherwise, the system cannot find the specific recipe you want to use.

If you have predefined a fixed lot size in the material master record of the material you want to produce (MRP1 screen), the system proposes the lot size in this field.

Order start date or Order finish date: Depending on the scheduling type, you must specify either the order start date or the order finish date, or both.

For example:

If you want to schedule forwards, specify the order start date. If you want to schedule backwards, enter the order finish date. If you do not want to schedule your order, specify both the order start date and the order finish date.

Process orders are generally scheduled backwards.

18 April 2001


Creating Process Orders With Material & Master Recipe

Scheduling Type: Here, you enter a key that specifies how the order is to be scheduled. The system proposes the value that has been defined in the scheduling parameters for the selected order type in Customizing.

SchedMargin key OR Float before production, Float after production and Release period The floats before and after production and the release period are specified via the scheduling margin key:

If you specify a scheduling margin key, the system fills these fields automatically. If you do not specify a scheduling margin key, you can enter a float before production, a float after production, and the release period with the corresponding number of days.

Priority: You can allocate a level of priority to the order. However, this field is only used for information purposes and does not influence processing of the order.

5. If you have only created one production version for the material you want to produce, choose Continue. If the validity period and the lot-size range of the production version match those of the allocated master recipe and alternative BOM, the data is copied from the master recipe to the process order.

If you have created more than one production versions, there are several different ways to choose a production version (see Production Version Selection [Page 20]).

6. If necessary, also enter a long text by choosing . Save the text and choose Back.

7. Choose Operations.

The operation overview [Page 30] appears.

8. If you do not want to change the data that was copied from the master recipe or the bill of material, save the process order now.

For information on how to change the data now or later, see Changing Operation/Phase Data [Page 31].

April 2001 19


Production Version Selection

Production Version Selection Use When you create an order, you select a Production Version [Ext.] to determine a suitable recipe along with the corresponding material list. Which production version is used, can be controlled in different settings.

If you create a process order without a production version, the system does not copy the formulas for material quantity calculation.

Prerequisites Suitable production versions have been created in the master recipe or material master record (see Maintaining Production Versions [Ext.]).

Features You can specify that the production version is selected:

Automatically or manually Depending on a quota arrangement

Activities You control production version selection as follows:

Automatic/Manual Selection In Customizing for Process Orders (section Define order-type dependent parameters, Production version field), you determine whether the production version is selected automatically or manually. As a prerequisite, the following settings must have been made for selecting alternative BOMs (material master, MRP4 view, Selection method field):

Selection by production version In this case, the system uses the alternative BOM that is defined in the valid production version. The lot-size range and the validity period of the production version apply.

Selection only by production version In this case, the system uses the alternative BOM that is defined in the valid production version. The lot-size range and the validity period of the production version apply. If no production version is found, the system cannot create a production order or a process order.

Selection According to Quota Arrangement To (automatically) select a production version depending on a quota arrangement, you:

Maintain the data on the quota arrangement in Customizing for Process Orders (section Operations, Quota Arrangement): number range, quota arrangement usage

Enter a quota arrangement usage in the material master record of the material you want to produce that includes production or process orders (MRP2 view, Quota arr. usage

20 April 2001


Production Version Selection

field) and choose Selection only by production version as the selection method (MRP4 view, Selection method field)

Maintain the quota arrangement for the material (Logistics Production - process Process order and then Environment Master data Maintain quotas). Enter the following data:

E (internal procurement) as the procurement type (column P) E (in-house production) as the special procurement type (column S) The production version. Make sure that it is also valid for the quota arrangement

period. If you use possible entries help to select the production version, make sure to delete the value entered in the PPI field (plant from which the material is procured) afterwards.

The quota for the usage of this production version If required, a maximum quantity: the production version is not used once this quantity

has been reached

If required, a priority: the system only uses the production version for which the lowest value not equal to zero has been specified (highest priority = 1). If you also entered a maximum quantity, the system uses the production version with the next priority once this quantity has been reached.

For more information about quota arrangements, see

Maintaining a Quota Arrangement [Ext.] Determining the Source under a Quota Arrangement [Ext.] Revision of Quota Arrangement [Ext.] Monitoring Quota Arrangements [Ext.]

Co-Products: Special Features When you create a process order, the system selects the following production versions in the sequence specified below, provided that the quota arrangement does not define the sequence:

1. All valid production versions for the material, including those in which the material is used as a co-product in a BOM item

2. If the Co-product indicator has been set for the material in the material master, all valid production versions for other materials whose BOM contains the co-product as a BOM item.

However, these production versions cannot automatically be copied to the process order. They are not taken into account in material requirements planning, product costing, and repetitive manufacturing.

April 2001 21


Selecting Production Versions Manually

Selecting Production Versions Manually Prerequisites If you always want to manually select one production version from several possible versions when you create an order, you must define this in Customizing for Process Orders (section Define order-type dependent parameters, Production version field).

Procedure If several production versions with overlapping lot-size ranges and validity periods have been created for the material, you can select a production version after you have entered the required data on the Create Process Order: Header screen (see Creating Process Orders with Material and Master Recipe [Page 18]). To select a production version, proceed as follows:

1. If manual selection of production versions has been defined in Customizing, the list containing available production versions is displayed directly. If only one production version exists, the system copies it directly instead of displaying it first.

If automatic selection of production versions has been defined in Customizing, choose Production version to display the list of available versions.

If required, you can choose Versions: overview to display a list containing all production versions for the material you selected.

2. On the Select Production Version for Material screen, select the production version you want to use.

3. Choose Choose to copy it to the process order.

If the settings in Customizing or the production version itself prevent the system from creating a process order for the data you have entered, the system displays a log.

If you do not want to select a production version, you must cancel order creation.

22 April 2001


Selecting a Master Recipe

Selecting a Master Recipe A master recipe is used to specify the operations and phases required in a production process. When you create a process order, the system selects a master recipe. The individual operations and phases of the master recipe, as well as the material list and other recipe data, are taken over into the process order.

In special cases, you may want to create a process order without using a master recipe. This may be the case, for example, if you want to create an order for unplanned rework.

In Customizing, you can specify whether a master recipe has to be selected as well as which criteria should be used in the selection process.

April 2001 23


Parameters in Customizing

Parameters in Customizing You can determine in Customizing:

whether a master recipe has to be selected whether selection should be carried out manually or automatically search criteria priorities, such as status of a master recipe

24 April 2001


Validity of the Recipe

Validity of the Recipe In order for a master recipe to be selected for a process order, the recipe, as a rule, must have the status Released (depends on your chosen settings in Customizing).

In addition, the system only considers for selection recipes that match up with the data you have specified in your process order.

1. The total quantity you have specified in your process order must lie within the charge quantity range you specified in your master recipe. If the system cannot select a recipe, it reselects without using the charge quantity.

2. The order dates you have entered in the process order must be valid for the master recipe you want to select. For example:

if you enter the order start date, the system uses this date as the transfer date of the master recipe.

if you enter the order finish date, the system calculates the transfer date of the recipe by subtracting the in-house production time independent of the order quantity defined in the material master from the order finish date.

Manual or Automatic Selection In the case of manual selection, the system selects all master recipes for this material which are valid on the transfer date. You can select the required master recipe from the list.

In the case of automatic selection, the system attempts to select a master recipe according to the specified criteria. If, however, the system cannot select a master recipe automatically, it will list all the master recipes available for your material. You can then select the required master recipe from this list.

April 2001 25


Automatic Master Recipe Selection

Automatic Master Recipe Selection When you create a process order with a material, you enter a material, the quantity of the material to be produced and a basic order date. During automatic selection of a master recipe to match this data, the system attempts to select according to the following criteria:

1. Material: The system first searches for all master recipes available for this material. 2. Quantity: The system then searches for all master recipes which have a charge quantity

range that corresponds to the specified order quantity. If there are no recipes with a suitable range, the system continues its search without taking charge quantity ranges into account.

3. Order dates: The system then calculates the date on which the master recipe must be transferred into the order. Please see Validity of the Recipe [Page 25] in this documentation.

4. Production version: The system searches for production versions valid for this material at this date. Please see Selecting a Production Version [Page 22] in this documentation.

For information on the sequence, refer to the log Read master recipe.

Selection Priorities

Selection Priorities You may find that several master recipes meet all the selection criteria for automatic recipe selection.

In this case, you can specify certain priorities in Customizing, according to which the system can then select a specific master recipe.

You can set priorities in Customizing for the following entries:

For the task list type (master recipe = 2) For the usage (such as production) For the status of the master recipe (such as released) Example: Selection Priorities [Page 28]

April 2001 27


Example: Selection Priorities

Example: Selection Priorities You can determine the following priorities in Customizing for plant 1 and order type PI01:

Task list type Usage Status

1. Master recipe Production Released

2. Master recipe Production Created

3. Master recipe General maintenance Created

In this example, the system first searches for a master recipe with the usage Production and the status released. If a master recipe matching these criteria does not exist, the system searches for a master recipe with the usage Production and the status created. If no master recipes match these criteria, the system then searches for a master recipe with the usage General maintenance and the status created.

28 April 2001


Automatic Batch Creation

Automatic Batch Creation Use You use this function to create a batch for the material to be manufactured.

Features You can make the following settings in Customizing (production scheduling profile):

No automatic batch creation in the process order Automatic batch creation on order creation Automatic batch creation on order release In Customizing for Batch Management, you can configure the system so that batch numbers are assigned automatically. If you do not do this, the system will ask to assign batch numbers automatically when you create and/or release the order.

April 2001 29


Operation Overview

Operation Overview This screen contains the operations and phases the system has copied from the master recipe and scheduled for the process order. The following information is provided:

The operation number (This number determines the sequence in which the operations are processed.)

The phase number of existing phases The number of the superior operation for each phase The resource that is to be used for carrying out the operation The control key. It determines how the operation/phase is to be treated (for example,

whether the phase must be reported, whether it can be printed, etc.).

The standard text key of the operation/phase if it has been defined for the operation description

The long text indicator which specifies whether a long text exists A short description of the operation/phase If you choose menu options Goto 2-line operation overview to access the operation overview, the following additional information is displayed:

The order start and finish dates The current status of the operation or phase (for example, whether the operation has been

created or is already released)

Whether material components are assigned to the operation/phase Whether at least one secondary resource is assigned to the operation/phase

30 April 2001


Changing Operation/Phase Data

Changing Operation/Phase Data Use In the operation overview, you can change operation/phase data both in the create mode and change mode.

Procedure 1. Choose Operations. The operation overview appears.

2. Depending on the data you want to change, select the operations and/or phases to be processed, and choose a processing type:

From the Operation Overview screen, you can also access the corresponding detail screens for changing the material list or material quantity calculation [Ext.] (via Materials to the material list and from there via to material quantity calculation).

April 2001 31


Changing Process Instructions

Changing Process Instructions Process instructions are copied from the master recipe and displayed on the Process Instruction Overview screen when you create a process order.

You can

add/delete process instructions add/delete process instruction characteristics for process instructions

You maintain process instructions in exactly the same way as during master recipe maintenance. For more information, see Process Control Data.

In addition, you can create process instructions manually if they contain process-specific data that cannot be transferred to the process instruction automatically. For more information,see Maintaining Process Instructions on the Charateristic Overview [Ext.].


32 April 2001


Assigning Values to Process Instruction Characteristics

Assigning Values to Process Instruction Characteristics In Customizing, you define process instruction characteristics for process instruction categories. You can assign values to process instruction characteristics:

in Customizing in the master recipe in the process order

As a prerequiste for the creation of control recipes values must have been assigned to all process instruction characteristics. These can be classified as follows:

process instruction characteristics that are not defined for automatic value assignment and for which you have to enter values manually

process instruction characteristics that are defined for automatic value assignment, where

- you can initiate the value assignment in the process order (function Assign values autom.) - you can enter the values manually in the process order (even after the function Assign values autom. has been executed, for ex. to change generated values) - during control recipe creation, the system automatically assigns values to all those characteristics that have not been assigned values as mentioned above

To assign values to process instruction characteristics in the process order, proceed as follows:

1. Select the desired phases in the operation overview and choose Goto PI overview. 2. Select the desired process instruction characteristics in the process instruction overview

and choose Goto PIC overview. 3. Assign values to the process instruction characteristics as follows :

Characteristics with indicator T (for value assignment with long text, X in column T) : i) Select the characteristic.

ii) Choose Edit Long text. iii) Enter the long text and save it.

Characteristics without indicator T : Enter the desired value in the field Characteristic value.

Characteristics with indicator A (defined for automatic value assignment, X in column A) :

Enter the desired value in the field Characteristic value (= manual value assignment); or

select the characteristics and choose Edit Assign values autom.; or do not assign a value at all.

April 2001 33


Assigning Values to Process Instruction Characteristics

Use field help for information on the logic used for the automatic value assignment (in column A for the desired process instruction characteristic).

When the control recipe is created, values are assigned automatically only to those process instruction characteristics defined for automatic value assignment to which no values have been assigned so far.

If necessary, you can also change values (exception: process instruction characteristics for which a change has been excluded during Customizing, for example, the order number) or delete values. To delete a value, select the desired process instruction characteristic and choose Edit Delete values.

In addition to this, you can add further process instruction characteristics in the process instruction characteristic overview. You add process instructions characteristics in the same way as during master recipe maintenance. For more information, see Maintaining Process Instructions on the Characteristic Overview [Ext.].

34 April 2001


Creating Process Orders with a Material and Without a Master Recipe

Creating Process Orders with a Material and Without a Master Recipe Use You can create a process order without a master recipe if, for example, you want to produce one specific material in one specific process.

Prerequisites If you specifically do not want to use a master recipe when you create a process order, you can set the respective parameters in Customizing.

These parameters specify how the system is to proceed if no master recipes exist for the material.

If the parameters specify that recipe selection is not required, the system creates a process order in which it automatically creates one operation. It proceeds as follows:

If default values are maintained for the automatic generation of an operation, the system uses these values to automatically create an operation in the order.

If no default values are entered in Customizing, the system creates one operation, with control key 0001 and operation number 0010.

If you do want to use a master recipe when you create a process order, but recipe selection is not possible even if the parameters specify that recipe selection is required, the system issues a termination message, and you must restart order creation.

You can restart the master recipe selection process at any time prior to the release of the process order.

Procedure 1. Choose Logistics Production - process Process order Process order Create

With material. The Create Process Orders: Initial Screen appears.

2. Enter your material number, plant (production and/or planning plant), and process order type. Choose Continue. The Create Process Order: Header - General Data screen appears.

3. Enter the total quantity of material, which in this case is not dependent on a pre-specified quantity. Also enter the order dates and the scheduling type and choose Continue. A dialog box appears informing you that no material lists exist for this material.

4. The dialog box asks if you want to use a different material list.You have two choices:

If you choose Yes, you must enter a material for which a material list already exists. The system then uses this material list for the process order.

If you choose No, an operation is generated for the order (operation 0010). 5. Choose Materials to enter the components for your process order.

April 2001 35


Creating Process Orders with a Material and Without a Master Recipe

36 April 2001


Creating Process Orders Without a Material and With a Master Recipe

Creating Process Orders Without a Material and With a Master Recipe Use You can create a process order without a material and with a master recipe. You do this, for example:

If you want to use a process order for a reworking procedure If you want to use a cleanout recipe

Procedure 1. Choose Logistics Production process Process order Process order Create

Without material. The Create Process Order: Initial Screen appears. 2. You must enter the following in this screen:

Recipe group: Enter the name of the recipe group you want to use in this process order. Recipe: Enter the number of your recipe in this group. Plant: This is the plant in which your order will be processed. Process order type: Enter the order type, which defines internal or external number assignment.

3. Choose Continue.

4. Make the same entries as described under Creating a Process Order With a Material. Once you have created the process order, the system will copy all the data from your master recipe, but not the material list.

April 2001 37


Creating Process Orders Requiring Approval

Creating Process Orders Requiring Approval Use For production in compliance with Good Manufacturing Practices (GMP), process orders must be approved before production. You can do this in the following ways:

Create with approved master data (see below) Individual approval Integration Master data is approved in engineering change management. You therefore require the Engineering Change Management (LO-ECH) component to do this.

Prerequisites You make the following settings for order types to specify that an order must be created with approved master data (see Customizing for the Process Order, Order-Dependent Parameters, Mast. data tab page):

For master recipe selection: Must be used with master recipe, automatic selection Must be used with master recipe, manual selection

The Approval required indicator is set. For collective orders, you must also make these settings for the order types of subordinate orders.

Features Master Data Selection When you create a process order requiring approval, the master data selection procedure is the same as for orders that do not require approval.

Checking the Approval The system then checks whether the master data has been approved. Before the process order can accept the master data on which it is based (recipe, BOM, production version) as approved, the following prerequisites must be met:

The master recipe used must have the change rule with an engineering change order without change type or an engineering change order with change type.

The recipe or one of its subordinate objects (for example, phase, secondary resource) and the corresponding production version have been changed with at least one engineering change request. The BOM can, but does not have to be processed with an engineering change request.

For each of the objects mentioned above, the engineering change request whose due date is the closest before the process order creation date must be released.

38 April 2001



Neither locked material components nor parts to be discontinued may be used. For planned orders, no changed to the material list may be made. For more information on the approval procedure for master recipe changes, see Engineering Change Management and Recipe Approval [Ext.].

If you manufacture in compliance with GMP, note the following:

The approval procedure is not supported for BOMs of phantom assemblies.

Further Processing If the prerequisites are not met,

The system statuses APNG (Approval not granted) and APRS (Approval withdrawn) are set. They do not allow the release of the order. The reasons for not approving or withdrawing the approval are documented in the log.

An individual approval is required for the order. If the prerequisites are met,

The system statuses APG (Approval granted) and APRC (Based on approved recipe) are set.

For the most part, only changes to MRP data in the order are allowed. Individually, the following data can still be changed:

Order dates Settlement rules Order quantity: The quantity can only vary within the charge quantity range defined for

the recipe.

Resources: You can use the Resource selection function to assign resources that meet the resource selection requirements for an operation.

Batches: Batches can be assigned for material components that are subject to batch management.

A withdrawal of the approval is possible, if required (for example, for major changes). After making the changes, an individual approval must be given for the order.

Exceptions when Approving Collective Orders Each order in a collective order is checked individually and approved independently of the other orders. If, for example, approval is denied for a subordinate order, approval is not withdrawn automatically for the higher-level order or the collection as a whole.

For each non-approved order in the collective order, an individual approval is required to meet the prerequisites.

The collective order cannot be released until all orders have been approved.

Converting Planned Orders Collectively

Converting Planned Orders Collectively Use If several planned orders exist in the same plant, you can simultaneously convert them into process orders via collective conversion. This is what is usually done in integrated production planning and control.

Procedure 1. Choose Process order Create With planned orders. The Collective Conversion of

Planned Orders: Initial Screen appears.

2. Enter the planning plant, the MRP area and the MRP controller of the process orders you want to convert. Enter the process order type with which the process orders are to be created. The selection criteria opening date (from - to), material, and sales order are also available.

If you select without a planning plant, the MRP controller you enter cannot be checked. In this case the system will warn you.

In the Material field you can search with any character string (for example, A*, for all materials starting with the letter A).

If you want to limit the selection of the planned orders to be converted according to your opening date, you can also enter an interval in the Opening date range fields. If an opening horizon is already defined in your user master record (parameter IDs, AEV, and AEB), the values are automatically suggested by the system.

3. Choose Continue.

The system lists all planned orders that correspond to the selection criteria you entered. You can display a planned order by double-clicking it (number of the planned order in the Planned order column).

4. Select the planned orders you want to convert. Alternatively, you can delete planned orders you do not want to convert from the list by choosing . You can then choose to select and convert the remaining planned orders together.

In the list of the selected planned orders, you can call up dependent objects by double-clicking a planned order or material.

5. If necessary, change the order type of the selected planned orders. If you specify an order type which requires external number assignment for a planned order, you must enter an order number for the order.

6. Choose Convert.

The system converts all selected planned orders.

A log is created for each planned order for which the conversion is called up. You call up this log by choosing in the Result column.

April 2001 41


Converting Planned Orders Collectively

You can make a new selection of planned orders at any time. To do this, display the selection area with Selection parameter on/off, enter the selection criteria and choose .

Only planned orders which allow in-house production are proposed for selection. To convert planned orders into requisitions, choose Logistics Production - process MRP Planned order Convert pur. req. Collect. conversion.

42 April 2001


Converting Planned Orders Individually

Converting Planned Orders Individually Prerequisite The Conversion indicator must be set for the planned order you want to convert. The material must allow in-house production.

Procedure Choose Logistics Production - Process. 1. Choose Process order Create With a planned order. The Create Process Order:

Initial Screen appears.

2. Enter the planned order number as well as the order type of the process order you want to create.

3. If the order type you have entered requires external number assignment, you must also enter the number of the process order you want to create in the Process order field. Choose Continue.

The system copies all the data contained in the planned order, such as order quantity and order dates. When the system selects a valid master recipe, all the recipe data, such as operations and phases, resources and material list components are copied into the process order.

4. Check the data copied from the planned order and change it if necessary.

5. Save the process order.

April 2001 43


Partially Converting Planned Orders

Partially Converting Planned Orders Use Use this procedure if you want to process a planned order in partial quantities. A process order is generated for each partial quantity.

Procedure You can call up the function for partial conversion from various locations in the system.

1. Depending on where you are in the system, choose in the following ways:

If you are Choose

In the SAP menu Logistics Production - Process Process Order Create with a Planned Order. Set the Partial conversion and choose Continue.

In the stock/requirements list A planned order by double-clicking it in the Additional Data for MRP Elements dialog box, and choose SubProcOrd.

In the MRP list A planned order by double-clicking it in the Additional Data for MRP Elements dialog box, and choose SubProcOrd.

In material requirements planning

Planned order Convert to proc. order. Individual conversion, set the Partial conv. indicator, and choose Continue.

2. If you want to carry out several partial conversions, choose .

3. Enter the quantities and dates.

For the conversion, the system uses the scheduling type defined in Customizing for the order type (and plant) entered. However, you can change it in the individual orders after the conversion.

4. Choose Generate.

The system generates one process order per line. Since these process orders are not yet saved, they are given temporary order numbers (for example, %0000000001).

As soon as a partial quantity is converted to a process order, the corresponding line on the screen cannot be deleted. To delete, you must cancel the transaction and carry out a new partial conversion.

5. If you want to make further changes in an order, select the line and choose Goto Process order. The Create Process Order: Header screen appears. After you have made the changes, choose Back to return to the screen with the partial quantities.

6. Choose Save.

Result The system saves the process orders.

44 April 2001


Partially Converting Planned Orders

A planned order that was partially converted is fixed. A fixed planned order is not changed in an MRP run. Its secondary requirements are reduced in accordance with the partial quantity entered.

If the total of the process order quantities created is smaller than the planned order quantity and the Delete planned order indicator is not set, the planned order quantity is reduced accordingly.

If you do not want to convert any more planned orders, irrespective of the planned order quantity still open, set the Delete planned order indicator.

If the total of the process order quantity created is greater or equal to the planned order quantity, the planned order is deleted.

If the master recipe selection for the process order to be created is controlled via a production version, the system always uses the production version that is valid for the original planned order quantity for a partial conversion.

April 2001 45


Scheduling

Scheduling Use In order processing, the scheduling function calculates the production dates and capacity requirements for all operations within a process order.

The scheduling process starts with the basic order dates (basic start and basic finish). The system either takes the basic order dates from the planned order, or you enter them manually on the header screen of the process order.

A process order is always scheduled automatically when it is created. In Customizing, you can specify whether you also want the order to be automatically rescheduled before saving whenever you make changes that are relevant to scheduling.

46 April 2001


Scheduling Types

Scheduling Types You can schedule a process order using the following scheduling types:

Forward scheduling: If you enter this scheduling type on the Main Header screen, the system schedules forwards starting from the order start date. If you enter the order start date, the system calculates the scheduled start and finish dates. If you enter the order start and finish dates, the system calculates the scheduled start and finish dates.

Backward scheduling: If you enter this scheduling type on the Main Header screen, the system schedules backwards starting from the order finish date. If you enter the order finish date, the system calculates the scheduled start and finish dates. If you enter the order finish and start dates, the system calculates the scheduled start and finish dates.

Scheduling to current date: If you enter this scheduling type on the Main Header screen, the system takes the current date as the order start date and schedules forwards. You then enter the order finish date and the system calculates the scheduled start and finish dates.

Only capacity requirements: If you enter this scheduling type on the Main Header screen, you will have to enter both the start and finish dates of the order. The system then calculates the scheduled start and finish dates.

The individual operations are not scheduled. The system calculates the scheduled start and the scheduled finish of the order by adding the float before production to the order start date and subtracting the float after production from the order finish date. It then writes the scheduled start and finish date into each of the operations.

April 2001 47


Scheduling Parameters in Customizing

Scheduling Parameters in Customizing Scheduling parameters are entered in Customizing for Process Orders (Operations Scheduling Define Scheduling Parameters) for each order type, plant and production scheduler (specified in the material master). Parameters that influence the scheduling of a process order are described below.

Scheduling Type The scheduling type [Page 47] determines how scheduling is carried out (for example, backwards). When you create a process order, the scheduling type is proposed on the order header screen. You can, however, overwrite this scheduling type in individual process orders.

Current Date Scheduling In Customizing, you can specify that an order is to be rescheduled as soon as it is delayed by a certain number of days. If the order start date lies further in the past than the specified number of days, the system will automatically carry out current date scheduling during the next scheduling run. Current date scheduling is forward scheduling, starting from the current date, which is reduced as much as possible (see Reduction Measures [Ext.]).

Rescheduling You can specify that a process order is to be rescheduled when you save it (Schedule automatically indicator). If changes are made to the order that are relevant to scheduling and this indicator is not set, the order is given status NTER (date not current).

48 April 2001


Changing the Scheduled Dates Manually

Changing the Scheduled Dates Manually You can change the scheduled start and finish of the order manually (Header Change in Dates Scheduled dates)

If you entered the scheduled start date manually in forward scheduling, the system uses this date as the fixed starting point for scheduling the order.

If you enter the scheduled finish date manually, the system uses this date as the fixed starting point for scheduling the order.

In both cases, you can overwrite the dates manually, and enter a different scheduling type. You can then reschedule by calling up the function Process order Functions Schedule.

April 2001 49


Order Floats

Order Floats Since malfunctions can never be completely avoided in the process flow, the system takes certain time-related floats (before and after production) in account when scheduling an order.

The float before production fulfills two functions:

It can neutralize delays during the staging of ingredients. It offers you the option of shifting production dates towards the present if capacity bottlenecks

occur at any of the resources involved. In this way, the float before production can also be used for capacity leveling as a float before and after production.

The float after production is used to neutralize unforeseen malfunctions in the production process so that these do not shift the scheduled finish of the order.

The float before production and the float after production are defined for each material via a scheduling margin key. This scheduling margin key, which is predefined in Customizing for Process Orders (Operations Scheduling Define Scheduling Margin Key), is copied automatically from the material master when you create an order.

However the times can be changed in the order.

The system calculates the scheduled start of the order by adding the float before production to the order start date. It calculates the scheduled finish of the order by subtracting the float after production from the order finish date.

The system subtracts the number of days defined in the release period from the scheduled start of the order, thus calculating the release date of the order.

50 April 2001


How the Control Key Influences Scheduling

How the Control Key Influences Scheduling The control key of the operation influences scheduling in the following way:

If, according to its control key, an operation is scheduled, the system calculates the duration and the dates of the individual operations.

If, according to its control key, an operation is not scheduled, the system assumes that all the operations have a duration of 0.

April 2001 51


Scheduling Phases

Scheduling Phases The duration of operations is defined by the duration of the individual phases. The scheduling function calculates the duration of each phase.

Each phase is scheduled using the scheduling formula stored in the resource data. A phase network is scheduled and the phase order dates are carried over to the operation. The start time of the first phase plus the finish time of the last phase is the start and finish of the operation.

If you have entered the default values of phases in the master recipe, the system uses this data to schedule (using the order dates in the initial screen).

If one phase of an operation is relevant for scheduling, the whole operation must be relevant for scheduling.

If the operation is relevant for scheduling, then at least one phase must also be relevant for scheduling.

If the scheduling indicator is flagged in the control key, the operation or phase is relevant for scheduling.

The duration of the superior operation is defined by the duration of the individual phases.

You create temporal relationships between phases by maintaining their relationships. You can also maintain relationships between phases of different process orders.

52 April 2001


Scheduling Rules

Scheduling Rules Working/Operating Time The working/operating time specifies when work can be carried out. The calendar used for scheduling distinguishes between workdays and non-working days. You can define a working/operating time in the system by specifying the start and end of shifts as well as the breaks for each workday.

The following rules apply:

If the unit of the phase duration is smaller than the unit day, the working/operating time per working day applies.

If the unit of the individual phase is greater than or equal to the working day, the phases are scheduled to the day on the basis of the calendar used for scheduling.

Additionally, there are specific rules for date determination (see the Date section in Date Determination at Operation Level [Ext.]) when times are exactly at work start, work finish, or midnight.

April 2001 53


Secondary Resource Scheduling

Secondary Resource Scheduling Use The system uses this function in master recipe or process order scheduling to determine the start or finish dates of the secondary resources.

Prerequisites You have chosen a scheduling type that allows secondary resource scheduling (see

Scheduling Type [Ext.]).

Secondary resources are not scheduled in scheduling types with the Only capacity requirements indicator. The scheduled start and finish dates of the recipe or order are used for these resources.

A control key has been assigned to the secondary resource in which the Scheduling indicator has been set (see Control Key [Ext.]).

If the Scheduling indicator has not been set in the control key, the system uses the dates of the superior operation or phase for the secondary resource.

Features The system uses the following data to determine the secondary resource dates:

The dates of the superior phase or operation The offset between the start and finish dates of the phase/operation and the secondary

resources, which has been defined in the detail data of the secondary resource (see Definition of Earliest and Latest Dates [Ext.])

The following rules apply in secondary resource scheduling:

A positive offset is added to the corresponding phase or operation date, that is, the secondary resource date is after the reference date

A negative offset is subtracted from the corresponding phase or operation date, that is, the secondary resource date is before the reference date

If no offsets have been defined for a secondary resource, the system uses the relevant phase or operation date as the secondary resource date.

The following graphic illustrates secondary resource scheduling.

Midpoint Scheduling and Capacity Scheduling

Midpoint Scheduling and Capacity Scheduling In capacity scheduling, the system takes work breaks into account.

Starting from a selected point in time, forward or backward scheduling can be carried out. Secondary resources are also scheduled according to capacity availability provided that they have the necessary control key.

56 April 2001


Capacity Requirements

Capacity Requirements Capacity Requirements of an Operation Operations have capacity requirements with a value of 0. The operations are not scheduled, as scheduling is carried out implicitly via the phases. The value is calculated at scheduling. The dates of calculated capacity requirements correspond to the dates of the operation.

April 2001 57


Scheduling Log and Results

Scheduling Log and Results For every scheduling run, the system creates a scheduling log in the process order. The log records all the information which is information on scheduling. If, for example, data relevant to scheduling is not maintained in a resource or in an operation, the scheduling run is not interrupted. Instead, the information is gathered in the form of messages in the scheduling log.

The scheduling log is used to:

collect messages issued by the system during the scheduling run sort and group together the system messages according to certain criteria.
