1. Concept of Warehouse Management

aster Data

Define control parameters for warehouse no

A warehouse number is an organizational unit in logistics that represents the company fromthe warehouse management view.

In the Warehouse Management System (WMS), you can define various control parametersat the warehouse number level. The control parameters will be:

1) Weights / units of measure2) Storage unit management is active or not3) Checking the data for capacity check

Version 1.2 5 of 72



G.V.Shivakkumar-


Define Number ranges

Define the number ranges for the objects which have automatic number assignment in theWarehouse Management system. These are:

Transfer requirement Transfer order Quant Posting change notice Group

If you are using Storage Unit Management, you must take the following objects intoaccount:

• Number range for storage units

The number ranges for the storage units cover all the warehouse numbers.

Version 1.2 6 of 72



G.V.Shivakkumar-


• Type of number assignment for storage units

Actions

1. Decide which number ranges you require for assigning the document numbers in

the Warehouse Management system.2. Create the number range intervals.

The following action is only required if you are using Storage Unit Management:

3. Create the number range LE for assigning the storage unit numbers and therespective assignment type (column VA ). Via the assignment type, you can defineper warehouse number whether, for example, external or internal storage unitnumbers are to be managed.4. Conversion of the storage unit numberIn Warehouse Management, you can determine per client (!) how the storage unit

number is to be converted. For information on the different input options, refer tothe field documentation.

Version 1.2 7 of 72



G.V.Shivakkumar-


Define storage types

Version 1.2 8 of 72



G.V.Shivakkumar-


Define Storage Type

A warehouse number is divided up into a number of storage types. A storage type isdefined on the basis of its spatial or organizational features (for example, high rack storage area, bulk storage area, and goods receipt area).

A storage type has the following features:

• A storage type does not have an address, but a short description.

• It is possible to store storage-type-specific material data.

• Within a storage type, inventory is executed for each storage bin.

Recommendation

These interim storage types (900-999) are required for various postings (for example, GR and GI postings, and differences) in WM. When you define your warehouse numbers, copythe interim storage types from warehouse number 001.

Activities

1. Create your storage types with the respective descriptions.2. Copy the interim storage types from warehouse number 001.

Important Note:

The placement strategy for ATC, AEC and ECO is decided as Addition to existing stock. Sowhile creating the storage type, the Put away strategy should be “I” – Addition to existingstock.

The removal strategy for all the materials without Shelf life expiration date check (SLED) willbe FIFI (Picking strategy – “F”) and for the materials with SLED check will be “H” – Shelf lifeexpiration date.

There will be two distinguished strategies one for materials without SLED check (Put awaystrategy – “I” and Picking strategy “F”) and one for material with SLED check (Put awaystrategy – “I” and Picking strategy “H”).

Define storage sections

Define Storage Sections

Version 1.2 10 of 72



G.V.Shivakkumar-


Within a storage type, a storage section is a series of storage bins with the samefeatures. These bins are used for the purpose of stock placements.

For stock placements, the following features of storage bins can be important:

•

distance to the turnover point

• loading capacity

• temperature

Standard settings

In the SAP standard system, sample entries are preset for the respective storage types inwarehouse number 001.

Note

• When you create a storage bin, you must enter a storage section.

• If you are using storage types without sections, you must define at least one storagesection (for example, 001) per storage type. The storage section in this case isidentical to the storage type.

Activities

Create your storage areas with the corresponding names.

Important Note:

There will be only one storage section for all ATC, AEC and ECO.




G.V.Shivakkumar-


Define Storage Bins




G.V.Shivakkumar-


Storage Bins

In the menu option "Storage bins", you define the configuration for the storage bins in theWarehouse Management system.

Before you create the storage bins (master data) you should work through this section aswell as the section "Define field usage - Storage bin data".

Define Storage Bin Types

Define Storage Bin Types

You can divide your storage bins into groups (for example, large storage bins, small

storage bins, and so on). A suitable storage bin is proposed by the system during stock placement in combination with the storage unit type.

Actions

1. Decide whether you want to use the "Storage bin type search".2. Create your bin types with the corresponding names.

Important Note:

Create only one Storage bin type for ATC, AEC and ECO.




G.V.Shivakkumar-


Define Blocking Reasons

Define Blocking Reasons

In the Warehouse Management system, you can block the following units for stock placements and stock removals:

• Storage types

• Storage bins

• Quants

• Storage unit

You can enter the reason for the block (for example, assembly work) using the indicator"Blocking Reason".




G.V.Shivakkumar-


Actions

Create your blocking indicators with the respective descriptions.

Define Storage Bin Structure

Define Storage Bin Structure

In the Warehouse Management system, you can create a sequence of similar storage binsautomatically.

Example for setting up similar storage bins

Define the parameters required for creating storage bins in the table "Storage BinStructures".

In this table, you must also define which warehouse master data (for example, storagesection, fire-containment section, and so on) you want to create when you generate thestructures.

Actions

1. Create your storage bin structures in the detail screen.2. From the menu bar (detail screen), select: "Environment --> Create bins" togenerate your storage bins.

Note

This function can also be found in the application menu (menu option "Master data").

Material

Material




G.V.Shivakkumar-


In this menu option you configure the material master records that are relevant for theWarehouse Management system.

Before you create the material masters, you should work through this section and thesection "Define field usage - Material master".

Define storage type indicators

Define Storage Type Indicators

With this indicator you can control whether certain materials are placed into or removedfrom stock in certain storage types with a higher priority. This leads to a classification of your materials and allows you to use the stock placement or stock removal strategiesin an optimum way.

Default settings

In the SAP standard system, examples are preset for warehouse numbers 001 and 002.

Actions

1. Classify your materials according to certain criteria (for example, small parts, andmaterials for block storage).2. Create your storage type indicators with the respective descriptions.

Further information

You will find more information on this subject area in chapter "Strategies - Storage typesearch"

Important Note:

Define 2 storage section indicators – one for the materials with SLED check and one for thematerials without SLED check. In Storage type search you have to define the priorityaccording to materials without SLED check and materials with SLED check.




G.V.Shivakkumar-


Define storage unit types

Define Storage Unit Types

With the indicator for the storage unit type, it is possible to distinguish pallets or othercontainers on which a material is stored or transported.

The classification of your storage units allows you to use the stock placement strategiesin an optimal way.

The storage unit type is taken into account during stock placements if you have activatedthe "storage bin type search".




G.V.Shivakkumar-


Default settings


ACTIONS

1. Decide whether you want to use the storage bin type search.2. Classify your storage units (for example, Europallets, wire boxes) according tocertain criteria (for example, certain packing height for Europallets).3. Create your storage unit types with the respective descriptions/names.




G.V.Shivakkumar-


Define storage section indicators

Define Storage Section Indicators

The storage section indicator divides materials into groups with the same

characteristics. With the storage section indicator, you can assign certain materialgroups to special storage sections.

With this classification method, you can use the stock placement strategies in an optimumway.

Default settings


Actions

1. Decide whether you want to use "storage section search".2. Classify your materials according to certain criteria (for example, fast-movingitems, bulky materials, extremely heavy materials, and so on).3. Create your storage section indicators with the corresponding description.

Strategies




G.V.Shivakkumar-


Strategies

In the Warehouse Management system (LE-WM) you support strategies in order toreceive proposals from the SAP System

•

Regarding which storage bins the goods are to be put away

• From which storage bins goods are to be picked.

There are two basic strategies in the system:

• putaway strategies

• picking strategies

With the help of these strategies, the SAP system can use the available transfer and

warehouse capacity optimally.

For each storage type, you must define a putaway and a picking strategy.

Recommendation

To be able to take a closer look at the processes involved in the storage bin search (that is,processes that involve interaction between the materials master data and the data from thesystem configuration menu in Warehouse Management), you can use the function "Log BinSearch".

You can call up this function from the preparation screens for stock placements and stock removals and from the single item screen for creating transfer orders (menu option"Environment").

This bin search log supports, on the one hand, the work of the project team in theimplementation phase and, on the other hand, the analysis of Customizing errors duringproductive operation.

Activate Storage Type Search

Activate Storage Type Search

For putaway or pick operations, the Warehouse Management System (WMS) must know:

• into which storage types materials can be placed

• from which storage types materials can be removed

In the WMS, a storage type is determined as follows:

1. In the case of a putaway, you generally know where the material for the

putaway is coming from. In the case of a pick, you generally know to where thematerial to be removed is to be transferred.




G.V.Shivakkumar-


Information on the location from where the material is to be picked is either storedin the transfer requirement or determined by the system using the WM movementtype.

2. The system must then know into which storage type the material should be

placed, or from which storage type the material should be removed. The table"Storage type search", which you are setting here, provides this information. In thistable, you store the preferred sequence of storage types to be searched for thematerial for putaways or picks.

If you have activated the storage unit check , this check also influences thestorage type search. In this case, the storage unit type from the transfer order isalso checked against the allowed storage units per storage type. The system findsthis information via the table "Allowed storage unit types / storage type", which youare also setting here.For further information on this subject, refer to the chapter Storage type search.

3. Furthermore, you can influence the storage type search using other indicators:

process indicator (for example, stock placement or removal) storage type indicator from the material master

stock category indicator special stock indicator storage class water pollution class (WPC)

reference movement type

The indicators storage class and water pollution class influence the storage typesearch. If you are not implementing Hazardous Material Management, you do notneed to pay attention to these parameters.For information on how to activate Hazardous Material Management, refer to thechapter Hazardous materials".

4. As mentioned above, different indicators influence the storage type search. If,however, you are using storage type indicators and you also have materials withdifferent stock categories or materials with different special stocks, the number of required entries in the storage type search table can become quite large.

To reduce the number of entries, you can define an access strategy for the storage

type search table. With the help of this access strategy, the system determines therequired entries in the storage type search table as follows:

The system first tries to find a suitable match, that is, an entry in thestorage type search table with all the relevant indicators from the materialmaster and, if available, from the hazardous material master.

If the system does not find a suitable entry in the storage type searchtable, it again tries to read this table, but this time using the accessstrategy.

Actions

Set the required parameters for the "Storage type search" in the specified sequence:




G.V.Shivakkumar-


1. Storage type indicatorUsing the storage type indicator, you can ensure that certain materials are onlyremoved from certain storage types or placed into certain storage types in the orderof preference you have defined.

You define the valid storage type indicators in the table for "Storage type indicators".

2. Storage type searchNow define the sequence of storage types to be searched by the system for stock putaway and stock pick proposals.

Make sure that you enter the correct indicators for stock putaway and stock pick inthe appropriate column.

If you want the system to search through the entire warehouse number for a stock pick, enter "***" (stands for stringent FIFO) as the storage type. The system willthen search the entire warehouse for the oldest stock of the material. The entry "+++" means that the system branches to the user exit to the stringent FIFO process(MWMTO013).

If you are using the 2-step picking procedure, make sure that the destinationstorage type of the pick step is used as the source storage type for distributing theaccumulated quantities. For the storage type search with the 2-step picking process,define activity type "2" (Column " Activity").

3. Movement type referencesIn the Warehouse Management component, you can set up the system so that foreach WM movement types certain storage types are proposed. If you want to usethis mechanism, set up the necessary reference movement types for the movementtypes concerned. These reference movement types must be taken into account inthe table "Storage type search".4. Access optimization for storage type search

Instructions for access strategy for the storage type search table

Activate Storage Section Search

Activate Storage Section Search

In the Warehouse Management System (WMS), a storage section is found in the followingmanner:

1. If the WMS is to search for a suitable storage section, it first searches for asuitable storage type. The storage type is determined during the storage typesearch.2. If the system has found a suitable storage type, it then determines thecorresponding putaway strategy. It finds this information in the "Storage type"table.3. Now the system must "know" into which storage section the material is to beplaced. The table "Storage section search", which you are setting here, provides this

information. This table contains a preference list for the storage sections into whichthe materials should preferably be stored. The system first searches for a bin in thefirst storage section. If it does not find a bin there, it continues its search in thesecond section, and so on.4. In addition, you can influence the storage section search using the followingindicators:

storage section indicator from the material master

storage class water pollution class (WPC)

Note: The WMS only takes the indicators "Storage class" and "Water pollution class"into account if Hazardous Material Management has been activated.




G.V.Shivakkumar-


To find out how to activate Hazardous Material management, refer to the section"Hazardous materials".5. In the WMS, you can enter the storage bins for putaway manually. In this case,the system checks whether the bin you have entered is in a storage section that isallowed for the material concerned.

Requirements

You must have the storage section check active. This check depends on the strategy youhave chosen. It can be implemented for all the putaway strategies, with the exception of the Fixed Bin Strategy.

Actions

Set the required parameters for the "Storage section check" in the sequence specified:

1. Storage section indicator You can assign a storage section indicator to each material. This indicator enablesyou to have materials placed into storage in special storage sections. You define the valid storage section indicators in the corresponding table.2. Storage section searchFor each storage section indicator, you can have up to ten storage sections in onestorage type. During putaway, the system first looks for a bin in the first storagesection; if it does not find a suitable bin here, it goes on to the next section, and soon.

2. Activate the storage section search.




G.V.Shivakkumar-





G.V.Shivakkumar-


Activate Storage Bin Type Search

Activate Storage Bin Type Search

The Warehouse Management System (WMS) can manage different sizes of storage binswithin a storage type. The storage bins are determined during the storage bin search:

1. It is generally known which loading equipment (storage unit type) is requiredto place the material into stock. This information is either

Entered manually OR Can be found in the material master.

In this case, the SAP System suggests the relevant storage unit type for the

putaway as a default.

2. Then the WMS checks if the storage unit which is to be placed into stock may beput away in the storage typed determined by the storage type search.

The table "Allowed storage unit types per storage type" contains details on whichstorage unit types (SUTs) may be used in which storage types.

This table defines which storage unit type may be used within each storage type. Upto 10 storage units may be assigned per storage type.

If more than 10 storage units are required per storage type, it is possible to activatethe weak SUT check .To do this, enter *** in this table as the allowed SUT. This has the effect that, intheory, all SUTs are allowed for this storage type. The system then searches for abin that matches the storage unit type according to the allowed storage bin typeper SUT.

3. Then the system searches for a suitable storage bin using the putaway strategy.

o For this purpose you have assigned a storage bin type to each storage bin

in the master data.

o Via the table "Storage bin type search" the WMS finds information on which

SUTs match which storage bin types.The search for a subsequent storage bin type is restricted to the permittedstorage bin types which are run through sequentially according to thesequence of entries in this table.

4. If you manually enter the storage bin during putaway, the WMS checks if the SUTmay be used on the relevant storage bin.

Requirements

The storage unit type check parameters must be activated. This check is independent of aparticular strategy. You can use it for all putaway strategies.




G.V.Shivakkumar-


Recommendation

If you wish to implement the above weak SUT-check , check your table options exactly asperformance problems may arise if the customizing option is not properly set.

The following example should illustrate these problems and their solution:

• Storage bin types P1 P2 P3 P4 P5 are allowed for storage unit type E1. E1 is to beplaced in stock in storage type 001. Here there are only storage bins of type P0.

• Normally E1 would not be included in the storage unit types allowed for storage type001. The WMS recognizes this and searches for a bin in the next storage type.

• A weak SUT check is when the database is accessed 5 times unsuccessfully. Thisnumber increases depending on how many different storage sections you work withat one time.

You can check the Customizing options via the storage bin determination log (transportorder management). Multiple access to the database does not greatly impairperformance. The number of times the database is accessed in this way can be decreasedusing an optimized storage type search.

Activities

Set the parameters for bin type search in the following sequence:

1. Bin types

Divide your storage bins into groups (for example, large bins, small bins).2. Check your warehouse master data and, if necessary, fill in any missing storagebin types.3. Storage unit typesClassify your storage units (for example, by palette type).4. Check your material masters and add palletization data, if this has not alreadybeen done.5. Allocation of storage unit types / storage typeFor each storage type, define which storage unit types may be placed into stock inthis storage type.6. Allocation of storage unit types / storage bin types

For each storage bin type, define which storage unit type may be put away.7. Activate the storage unit type control function in the putaway control parametersfor the desired storage bin.

Put away Strategies

Putaway Strategies

The stock placement strategy is a procedure in the Warehouse Management systemwhereby the system searches for a suitable storage bin within a storage type or a

warehouse number using a particular strategy.

The Warehouse Management system supports the following strategies:

Fixed storage bin

Open storage Addition to existing stock Empty storage bin

Pallets (storage units) Bulk storage Near to picking fixed bin

No strategy (manual bin location assignment)Define Strategy for Fixed Bins




G.V.Shivakkumar-


Define Strategy for Fixed Bins

The "fixed bin" stock placement strategy is used for storage types in which a material isassigned to a particular storage bin.

This strategy is used mainly in storage types where picking is carried out manually (forexample, in small parts storage areas with manual picking).

Default Settings

In the SAP standard system, warehouse number 001 and storage type 005 are preset forthe strategy "Fixed bin".

Actions

1. Decide whether or not you want to use this stock placement strategy.

2. If you have already created material masters, maintain the storage type data of the material masters that is required for fixed bin management.3. Enter the indicators for the stock placement strategy "Fixed bin" in the detailscreen.




G.V.Shivakkumar-





G.V.Shivakkumar-


Define Strategy for Addition to Existing Stock

Define Strategy for Addition to Existing Stock

Using this stock placement strategy, the SAP System tries to place a quantity of materialinto a storage bin in which the material already exists. To add to existing stock, theremust be sufficient remaining capacity in the storage bin. So you must switch on thecapacity check for the relevant storage type to implement the strategy addition toexisting stock .

If the system does not find a storage bin with enough remaining capacity in this storagetype, it will call up the strategy "Empty storage bin".




G.V.Shivakkumar-


Activities

1. Decide if you want to use this putaway strategy.2. Decide which type of capacity check you want to use.

You can find out which capacity check types are currently supported via the possible entriesfield capacity check .

1. Enter the indicator for the putaway strategy "addition to existing stock" in thedetail screen.2. Activate the capacity check.

Stock Removal Strategies

Stock Removal Strategies




G.V.Shivakkumar-


A picking strategy in the Warehouse Management System refers to a procedurewhereby the system searches during a pick for a suitable quant within a storage type ora warehouse number.

The Warehouse Management system supports the following picking strategies:

• FIFO (First In First Out)

• Strict FIFO

• LIFO (Last In First Out)

• Partial quantity

• Large/small quantities

Define FIFO Strategy

Define FIFO Strategy

With the stock removal strategy FIFO (First In First Out), the warehouse managementsystem proposes the oldest quant in each storage type from which you want to removestock.

The system calculates the age of a quant using the date of the goods receipt posting thatwas set in the quant by the transfer requirement and the transfer order.

Activities

1. Decide whether or not you want to use this stock removal strategy.2. Activate the stock removal strategy "FIFO" in the stock removal control of therelevant storage type.




G.V.Shivakkumar-


Define Strategy for Shelf Date Expiration Date

Define Strategy for Expiration Date

With this stock removal strategy, you can influence the search of the materials underconsideration of the shelf life.

Material managed according to shelf life expiration date is found as follows in theWarehouse Management System




G.V.Shivakkumar-


1. You must have activated the shelf life expiration date management in therespective warehouse number.2. For each storage type , the shelf life expiration date (SLED) strategy must be

activated, providing you do not work use the stock removal strategy "Strict FIFOprinciple".3. The minimum remaining shelf life must be maintained in the material masterrecord (storage view).Materials for which this remaining life is not maintained are searched for with stock removal strategy "FIFO".

Activities

1. You have to decide whether you want to use this stock removal strategy.2. Activate the shelf life expiration date management for each warehouse number.

The shelf life expiration date management must be activated at warehousenumber level. In the application, this activation causes that the shelf life expirationdate is a required entry during stock placements, depending on the material andmovement type. In some analyses, the shelf life expiration date of materialsmanaged according to shelf life expiration date is displayed instead of the GR date. Activate the shelf life expiration date management.3. Activate the stock removal strategy Activate the stock removal strategy expiration date in the stock removal control forthe relevant storage type.

Further notes

If you are using the stock removal strategy "Strict FIFO principle", please refer to thesection "Define Strict FIFO Principle" strategy for more information on the"Shelf Life Expiration Date".

Activities




G.V.Shivakkumar-


Activities

In this unit, you set the following activities in the Warehouse Management system:

• Transfers

• Differences

• Print control

• Physical inventory

• Appointments

• Define transaction parameters

Transfers

Transfers

In this section, you set the configuration for the transfer of goods.

This includes the following:

1. Transfer types2. Movement types

3. Requirement categories4. Posting changes and stock transfers

Define Requirement Types

Define Requirement Types

Movements and stock records in the Warehouse Management System contain a reference tothe originating document.

The requirement category describes the origin type (for example, goods receiptfor a purchase order, and goods issue for the cost center).

The requirement tracking number describes the origin itself (for example, thepurchase order number, the cost center).

Actions

Create the requirement types for each warehouse number.




G.V.Shivakkumar-


Define Shipment Types

Define Shipment Types

In the Warehouse Management system, there are two types of transfers (movements):

• Movements that are also important for Materials Management(for example, stock placements and stock removals)

• Movements that only concern the warehouse(stock transfers within a warehouse, for example).

The transfer type is a suitable tool for reports (for example, all stock placements into astorage type, all stock removals from a storage type, and so on).

Note

The transfer type is not used in system control functions.

Standard Delivery

In the SAP standard delivery, all the relevant transfer types are preset.




G.V.Shivakkumar-


SAP Recommendation

SAP recommends keeping the transfer types delivered with the standard system. You canadd to these transfer types as required.

Actions

Define the transfer types for each warehouse number.

Define Movement Types

Define Movement Types




G.V.Shivakkumar-


The system processes Inventory Management movements (for example, goods receipt for apurchase order or goods issue to a cost center) using movement types. If the SAPsystem determines that a movement is relevant for Warehouse Management, it assigns aWM movement type to this movement via a table.

The movement type for the Warehouse Management system provides the informationrequired for stock placements and stock removals:

Interim storage type Coordinate of the interim storage bin

predefined coordinate dynamic coordinate fixed bin coordinate

Control indicator for processing, confirming and printing transfer orders

Indicator for storage type search.

For information on the links between the IM and the WM movement types and how tochange them, see the section Movement Types for Interim Storage Bins.

Standard settings

In the SAP standard system, all the relevant movement types are preset.

Recommendation

SAP recommends keeping the movement types delivered with the standard system.

Activities

1. Before you create movement types for a new warehouse number:

start with the configuration for the printer control delete the print codes then maintain the print codes when you configure the printer control

2. Create the movement types for each warehouse number using the copy function.

3. Define your own company-individual settings (for example, for the interim storagetypes) in the detail screen.




G.V.Shivakkumar-






G.V.Shivakkumar-



Using a posting change, you can change the material identification of stocks. A postingchange affects at least one of the following items:

material number plant stock category special stock

A stock transfer is involved if a quant is moved physically from its storage bin.

Posting changes and stock transfers always take place within a warehouse number.

Standard settings

For stock transfers and posting changes, the movement types in the series "3nn" are at yourdisposal.

For internal warehouse replenishment, use the WM movement type "319". You can use thismovement type as a copy sample for creating your own movement type.

Activities

1. Check all the movement types for posting changes, stock transfers, andreplenishment.2. Make your own company-required adjustments in the detail screen. For

replenishment movement types, you do not require the definition of therequirement type.3. If you want to use the functionality "Replenishment for fixed bin warehouse"(using the report RLLNACH1), you must define the storage types for whichreplenishment is to be used. Assign the appropriate replenishment type to the respective storage types.




G.V.Shivakkumar-





G.V.Shivakkumar-


Confirmation

Confirmation

In this section, you configure the system settings for handling differences and for confirming

transfer orders.

Handling Differences

The system posts differences that you find in the warehouse into a specific differencestorage type (for example, 999) whenever you

• Confirm a transfer order with differences.

• Perform a manual stock transfer to the difference storage type (for example, 999).

• Perform automatic stock transfer to the difference storage type (for example, 999)after an inventory with quantity differences.

In the WM system, you can classify differences according to cause (for example, breakage,theft).

Using the difference indicator, you determine the storage type and the storage bin to whichthe differences are posted.

For each difference indicator, you can save the percentage value for the deviation allowed,that is, starting from which the dialog box is to appear. Suppressing the dialog box is

appropriate for stock picks that cannot be done to the exact amount and where thedifference is cleared against the stock in the source bin.

Example

A warehouse worker guesses a 3 kilogram pick for a particular material and determines theactual weight further away from the bin. In this case, each pick is confirmed with adifference. It would be appropriate to have the dialog box suppressed so as to save thisextra step.

Confirmation Control

One important aspect of confirmation of transfer orders is the setting of the confirmationrequirement. This requirement means additional work for the user, but it also affords a highlevel of stock and information security.

The decision as to whether a transfer order item requires confirmation and whether it isconfirmed immediately depends on the parameters you set for your movement types andyour storage types.

• At the warehouse number level you define:

o whether there is to be separate confirmation of pick and transfer

• At the storage type level you define:




G.V.Shivakkumar-


quant are no longer updated, but only the destination storage bin and the quant storedthere.

SAP Recommendation

SAP recommends working with the stock placement and stock removal confirmationfunctions. The confirmation procedure is recommended for the following reasons:

• Stock in a storage bin should only be available after the actual putaway has beenconfirmed.

• Storage bins should only be released for further putaways after the goods putawayin the destination bin has been confirmed.

• A storage bin that is going to be emptied by a pending stock pick should already befilled with a putaway before it is really emptied.

• The posting of differences should be executed during the actual confirmation, andnot by means of a separate transfer order.

Include the confirmation process in your organizational procedures.

You can use the bar code for confirming transfer orders. This makes your work mucheasier.

Activities

1. Decide whether you want to confirm the transfer orders created in the SAP systemusing the confirmation procedure.2. Maintain the difference indicator for differences in TO confirmation.3. Maintain the indicator "Confirmation control/Warehouse number".4. Maintain the indicator "Confirmation control/Storage type".5. Maintain the indicator "Confirmation control/Movement type".

Define Print Control




G.V.Shivakkumar-


Define Print Control

In this section, you set the configuration data for print control.

Using the print control function, for example, you can define

• Which documents (that is, for transfer orders) are to be printed for goodsmovements.

• How these documents are to be printed (that is, which forms are to be used, howmany copies are to be printed).

• On which printer a document is to be printed automatically.

Using the print control functions, you have flexible control of the printing activities in yourwarehouse. This flexibility, however, means that setting the parameters is a complex task.

For this reason, we recommend that you take a look at the entire print control functionsfirst, and then analyze the "print situation" in your warehouse.

The number and type of settings you need for your print control depends on whether youare using the Storage Unit Management component. If you are not using this component,you only need to set the "standard" print control functions. However, if you are usingStorage Unit Management, you need to set both the "standard" print control functions aswell as the functions for storage units.

In this section, we describe the "standard" print control functions. These control the printingof transfer order slips.

The print control for printing specific slips for storage units is described in the chapterDefine print control for warehouses with Storage Unit Management.

You need the following settings for the "standard" print control function:

• Spool Indicator

Slips are always printed within the SAP system using the Spool function. For eachprintout, certain data needs to be passed on to the Spool file. Typical examples of such data are:

o Number of copies to be printed

o Dataset name of the printout within the Spool system

o "Print immediately"

o "Delete after print"

Using the Spool indicator, you define the most appropriate combinations of theindividual parameters you want to use.In the following settings (for example, the settings for the print code), you do not

need to specify these parameters each time. You only enter the spool indicator as atype of abbreviation.

determines the general print parameters through the print code assigned to themovement type. Afterwards, it checks the movement-specific print parameters. If one of these parameters (for example, for the form) is also defined in the print code,the system will use the movement-specific parameter.It is possible to override the definitions for label printing in the print code, depending

on the warehouse movement. You can also store an additional form for a combined picking list with the spool codeand the printer in order to print a combined document in parallel to single printingfor each TO item. This is only possible as an accompaniment to non-combined-printouts (indicator for combined printing in the print code) and is otherwise ignored.

• Assignment Printer - Picking Area

It can be useful to select a printer near the picking area for printing picking orders. Again you are faced with the question: How does the system proceed with automaticprinter determination, since it is possible to define a standard printer both in the

configuration for "Printer-Movement" as well as in the configurations "Printer -Storage Type", "Printer - Picking Area", and in the user master of each user?First the system checks whether a printer is set in the configuration "Printer-Movement". If so, the printer determination is complete at this point.If not, the system uses the parameter "PriSrcTyp" defined in the configuration"Printer-Movement" to decide how it will proceed.If the parameter is set here, the system checks if a printer is defined in the setting"Printer Picking Area" and then proposes this printer.If the system finds no printer, it searches in the setting "Printer - Storage Type" anduses this, if a printer is set.If the system cannot find a printer using the methods described above, it selects theprinter defined in the user master of the user currently logged on.If no printer is defined here, the system automatically proposes LP01. This writes thedata to the spool file.

• Assignment Printer - Storage Type

Here you can store one printer per storage type, in accordance with the printerdetermination logic described above.

• Assignment Print Code - Movement Type

A print code is assigned to each movement type. As described above, the generalprint information is determined by this assignment.

• Assignment Print Program - Warehouse Number

You must assign a print program to each warehouse number. The name of thestandard program is RLVSDR40.

• Print Control Multiple Processing

A print report is assigned to each warehouse number for printing a

combined transfer order. You can also configure the following:

o the print code




G.V.Shivakkumar-


o the printer

o the print time

• The print layout is set using forms.

Standard settings

All relevant print control tables are defined in warehouse number 001.

The following print programs are available:

• RLVSDR40 (general print program)

• RLKOMM40 (multiple processing)

Recommendation

Only use your own print programs if your print requirements are not met by the user exits inthe standard system. If you wish to extend the functionality of the program RLVSDR40, usethe user exit MWMD0001 to develop them. If you wish to extend the functionality of theprogram RLKOMM40, use the user exit MWMD0002. For further information onenhancements through the user exit, refer to the chapter Develop extensions.

Information on how to adapt forms in Warehouse Management is provided in the chapterDevelop forms.

Further Recommendations

1. Before you begin with table maintenance, you should first look at all tablescarefully and determine which ones you need.2. Then maintain the tables in the prescribed sequence.

Activities

1. Create the spool indicators for each warehouse number.2. Create the dependent printers for label printing.3. Define the sort profile for multiple processing.

4. Create the print codes for each warehouse number.5. Assign the printers to the individual movements.6. Assign the printers to the picking areas.7. Assign the printers to the storage types.8. Assign the print codes to the movement types.9. Assign the print reports to the warehouse numbers.10. Assign the print control to the multiple processing runs.11. Using the analysis program, check whether the settings comply with your needs.

Physical Inventory




G.V.Shivakkumar-


Physical Inventory

In this menu option, you configure the following system settings:

• Default values

• Types per storage type

• Differences

• Number ranges

Unlike the material-related physical inventory in the Inventory Management (IM) system,the Warehouse Management system supports inventory procedures based on the storagebin.

Define Default Values

Define Default Values

In this menu option you define:

• which data should be printed out on the system inventory record

• how the entry screen for the inventory count should be set up

Actions

Maintain the default values for each storage type.




G.V.Shivakkumar-


Define Types per Storage Type

Define Types per Storage Type

The Warehouse Management system (WM) supports the following inventory procedures:

• Annual inventory(ST)

Counting the material quantity in the storage bins at a fixed inventory date.

• Continuous inventory (PZ)

Counting a certain number of storage bins on any day in the fiscal year.

• Continuous inventory based on stock placement




G.V.Shivakkumar-


When a bin is occupied for the first time in the fiscal year, the system registers thatinventory has been taken for that bin. You can only use this inventory procedureunder certain conditions and must always check with the company auditor first.

• Continuous inventory based on zero stock check

This procedure can be activated by the SAP system if a storage bin is empty.

• Inventory through cycle counting

Counting of materials according to a pre-classification at different times during thefiscal year.

Requirements

You have coordinated your inventory procedure with the company auditor.

Actions

Maintain the inventory type for each storage type.

Define Differences and Document Limits




G.V.Shivakkumar-


Clear Differences (Interface to Inventory Management)

Clear Differences (Interface to Inventory Management)

In this section you specify the movement types for posting differences in InventoryManagement, and specify from which storage types this type of posting can be started.

Movement type:

In order to be able to post inventory differences to the interim record for differences,internal movement types are required.

The movement types used for this purpose come from the Inventory Management system,and refer to a movement type in the Warehouse Management system.

The interim record for differences is determined on the basis of these movement types.

Prohibit storage types:

Technically speaking, you can post from practically all storage types. However, it isadvisable to collect the differences in one storage type (999) and start the postings fromthere.




G.V.Shivakkumar-


Standard settings

In the SAP standard version, inventory movement types for Inventory Management arepreset in warehouse numbers *** and 001.

The settings for warehouse number *** are default values. If you require differentparameters for a warehouse number, you can add the difference movement types for therespective warehouse number.The system first searches for an exact match for the table entry, that is, with the warehousenumber. If it does not find a corresponding entry, the system will search for warehousenumber ***.

Recommendation

SAP recommends that you keep the preset movement types to avoid incorrect postings.

If you want to use the SAP standard system, you do not need to make new table entries foreach warehouse number. You can work with warehouse number ***.

SAP recommends setting this indicator for all storage types except the differencestorage type (999).

Activities

1. Analyze the entries for the default warehouse number *** and (if necessary)create the difference movement types for your warehouse numbers.2. Define your own company-individual settings for the movement types.




G.V.Shivakkumar-


Maintain Number Ranges

Maintain Number Ranges

In the menu option "Number ranges" you define number ranges for the inventorydocuments.

For each warehouse number you can create three number ranges:

• for the system inventory records

Here the users create the documents themselves.

• For transfer orders that initiate continuous inventory based on stock placement. Inthis case, the transfer order is the inventory document.




G.V.Shivakkumar-


• for the quant-by-quant cycle counting physical inventory

SAP Recommendation

Once you have defined your number ranges, you cannot change them if the data in the

number range intervals has already been used.

Take the long-term data quantity into account. Define your number range intervalsaccordingly.

Actions

1. Define your number ranges.2. Maintain your number ranges.
