CRP: Basic Work Center Settings for Capacity Planning
For a basic CRP scenario, it is necessary to have a work center and a routing referring this work center.
The work center represents a machine, a production line, an employee or a group of employees that will execute the work. On the work center, the basic settings for capacity and scheduling are defined.
This document provides a step-by-step to the creation of a work center focusing on the capacity planning and scheduling settings.
See document CRP Basic Settings Part 2 – Routing for a detailed step-by-step of a routing creation and document CRP Basic Settings Part 3 – Production Order for the creation of a production order relevant for capacity planning.
In order to create a work center, the basic transaction is t-code CR01.
Each work center is linked to one specific plant, therefore, here, we define the work center name and the plant.
It is also important to define the work center category. On this example we will use category 0001, which represents a machine.
On the tab Basic Data, it is important to define a usage that allows the work center to be used in production orders. In this example we will define usage 009, so that the work center can be used by all the task lists type.
The most important setting from the Basic Data tab is the Standard Value Key. The parameters defined on the standard value key are used by the scheduling and capacity requirements formulas. We will use the standard value key SAP1, delivered by SAP, since we will also use the standard formulas later. However, you can create your own standard value key and formulas on customizing.
On the tab Capacities we will define the formulas that will be used to calculate the capacity requirements. The formulas defined here will use the parameters from the standard value key defined previously. We will use the standard formulas SAP005 for setup and SAP006 for processing.
Here, it is also possible to define how the capacity reduction will occur. We are using the default option Formula-Related, however, if you want to explore different options, note 1789680 will be useful.
It is also important to click the button Capacity, in order to define the capacity header details.
Very important here is to set the flag Relevant to Finite Scheduling and the start and finish of our available capacity on the standard available capacity. It is also possible to define different intervals of available capacity or shifts for each day of the week by clicking the button Intervals and Shifts, however, this is not relevant in our example, as it is a basic setup.
On tab Scheduling similarly to what has been done on tab capacities, we will define the relevant formulas for scheduling.
Note that it is possible to check and test the formulas, by clicking the buttons at the end of the screen.
On the Costing tab, you can define the assignment to a cost center, activities and formulas to the cost calculation. This information is generally not relevant to capacity planning and scheduling.
Here, the most relevant setting for capacity planning is the Record Type Group, where you define if the standard value key parameter refers to setup or processing, for example. The already referred note 1789680 provides more information about this setting. If there is no record typ group assigned, the capacity reduction is executed with the first confirmation.
SAP Note: 1789680 - Capacity reduction proportional to service does not work as expected
