Introduction to Capacity Evaluation SAP AG

View Definition

2–2 May 1997

View Definition

Your role in the company determines which capacity evaluation view you require:

• The work dispatcher needs to find out what is in the order/operation pool for a

machine.

• The member of the sales staff wants to get information on the processing status of a

customer order.

• The plant manager wants to evaluate the capacity load of the work center groups and

their staff over the coming months.

Profiles

To meet these different requirements, you can set up profiles in customizing for capacity

planning to define the views. Relevant values necessary for the configuration of a

particular profile include the planning interval, the period split, the order types, the work 

centers or the capacity categories to be selected in the capacity evaluation for the current

view.

User Interface

The results of the capacity evaluation are displayed in tabular form as lists or in graphical

form. The following types of graphic are available:• Hierarchy graphics to display work center hierarchies

• Capacity load displays in vertical (column) or horizontal bar form

• Line diagrams to display input/output of requirements

• Gantt charts to display the earliest/latest dates

• Planning tables for the dispatching of orders/operations to the work centers (for

Release 3.0)

There is also a direct link between capacity evaluations and capacity leveling and so to

both types of planning table.

The interface to Microsoft EXCEL enables you to transfer the evaluated CRP data to aPC. You can use the functions of MS-EXCEL to make further calculations and edit the

displays.

Customizing

You can define the fields to appear in the lists, how they are to be sorted and grouped

with user-specific settings in customizing for capacity planning (see Selection in

Capacity Evaluation).

Function Library

Within the framework of capacity evaluations, the CRP system provides the different PPapplications with specific functions. The system can call up these functions

automatically from the applications or you can activate them by means of the user

interface.

This function library includes:

• Evaluation of the available capacity at the work center, with the option of cumulating

the available capacity using work center hierarchies and of managing different

versions of available capacity

• Calculation of capacity requirements to be distributed over the duration of the

operation using a distribution function

• Load analysis of the capacity requirements of planned orders and production orders

by means of various groupings, sortings and cumulation types.

Data Flow

Using R/3 master data such as material masters, routings and work centers, as well as

planned orders and production orders, data is created which can represent the available

capacity and the capacity requirements.

The available capacity specifies the output of a capacity per workday. A capacity is

generally allocated to one work center.

The capacity requirements specify the output that individual orders require of a

capacity at a particular time. The capacity requirements are calculated in lead time

scheduling.

In the capacity evaluations, capacity requirements can be compared with the available

capacities:

• The percentage capacity load as well as the remaining available capacity per work 

center is calculated in the Standard overview.

• The Capacity detail list displays per work center and per period which orders are

responsible for the capacity requirements.

• In the Variable overview, you can display various types of data used in capacity

planning in the form of a list. The layout of the list is user-defined.

With the help of these three types of evaluation and the graphics that belong to them the

CRP system (CRP = Capacity requirements planning) constitutes a very flexible tool for

carrying out capacity evaluations.
