Planning Components for a Production Line (Example)

You can use MRP areas to plan the procurement and staging of components on a particular production line. If, for example, you define an MRP area for the production storage location of an assembly line, the system plans the material requirements for the assembly line separately from all other requirements.

Example Data

Assembly A is produced on production line 1. Components B and C, which are procured externally, are necessary for the production and are withdrawn from storage location 0001.

Prerequisites

You create an MRP area of the storage location type for storage location 0001 in Customizing for MRP. You assign the MRP area to storage location 0001.

You assign this MRP area to the components B and C in the respective material master records by creating an MRP area segment. You enter storage location 0001 in the Storage loc. for EP field in the MRP area segment, as this is also to be the receiving storage location for the components.

You create a production version for production line 1 in the material master for assembly A. In this production version, you enter storage location 0001 as the issue storage location for the components.

Planning Procedure

In the planning run, the system calculates the dependent requirements for components B and C and determines the issuing storage location 0001 using the production version. This allows the dependent requirements to be assigned to the MRP area for storage location 0001.

When the system determines the procurement elements for B and C, it reads the external procurement storage location and uses this as the receiving storage location. This is also storage location 0001 so the procurement elements are assigned to the MRP area for storage location 0001.

You can use this procedure to selectively plan the components that you require on the production line.

If you do not work with production versions, you can also enter the issue storage location for the components in the BOM, in the work center using the supply area, or in the Issue stor. location field in the MRP data of the material master.
