Define MRP areas

In this IMG activty, you define the MRP area for every plant for which you would like to carry out material requirements planning separately.

When creating an MRP area, you enter the number, which must have at least 5 digits to avoid any overlapping with the plant MRP area, the description and the MRP area type. You must also enter a storage location as a receiving storage location. This storage location must, however, belong to the MRP area. Finally, you assign the storage location or the vendor number of the subcontractor to the MRP areas.

You asssign the materials to the MRP areas by creating a segment for the MRP area in the material master record.

There are basically three types of MRP areas:

• Type 01 for Plant

The plant MRP area initially contains the plant together with all its storage locations and stock with subcontractors. The plant MRP area is created automatically when you convert the existing planning file entries to planning file entries for MRP areas.

When you have defined MRP areas for storage locations and for subcontractors and you have assigned the materials, the plant MRP area is reduced by exactly this number of subcontractors and storage locations, as they are now to be planned separately.

If you have not assigned a material to an MRP area, that is, you have not created an MRP area segment in the material master record, the material will continue to be planned in the plant MRP area.

• Type 02 for Storage Locations

You choose this type for MRP areas that consist of one or more storage locations. A storage location can only be assigned to one MRP area.

• Type 03 for Subcontractors

You choose this type if you would like to define an MRP area for a subcontractor. You can only assign one subcontractor to an MRP area of the subcontractor type.

Example

You specifically want to plan the requirements for components of an assembly line. To do this, you define an MRP area of the type storage location and assign the storage location from which you are taking the components that are required on the line.

Preconditions

• You have converted the existing planning file entries at plant level to planning file entries at MRP area level.

• You have activated material requirements planning for MRP areas.

Activities

To define a new MRP area, proceed as follows:

1. Starting from the MRP area overview, choose New entries.

2. Enter the number and description of the MRP area. You can choose an alphanumeric MRP area number; it must, however, be 5 digits long.

3. Choose Save and then Exit.

4. Call up the IMG activity Define MRP areas again and select the MRP area and choose Storage location if you want to define an MRP area of the storage location type or choose Subcontractor if you want to define the MRP area for a subcontractor.

5. You assign one or several storage locations to an MRP area of the storage location type. You assign a subcontractor to an MRP area of the subcontractor type by entering the supplier number in the field MRPa. Sub.

6. Save the entries and choose Back.

Further notes

Due to the conversion of the planning file entries at plant level to MRP area level, the system has already created an MRP area of the type plant for every plant.
