Define the MRP areas for plant and storage locations.

An MRP area represents an organizational unit for which you can perform material requirements planning separately. In this step, you can define the MRP areas for plants and storage locations. By using storage location MRP areas, you can define single storage locations or groups of storage locations that are excluded from MRP planning on plant level or that have to be planned separately.

There are 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.

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

If you have not assigned a material to a storage location 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.

If you have defined MRP areas for subcontractors, it is not necessary to assign the materials to the MRP area. The assignment happens implicitly based on the existence of the MRP area for the subcontractor. The plant MRP area is reduced by exactly this number of subcontractors, as they are now going to be planned separately.

• 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. You also need to enter a storage location as a receiving storage location. This storage location must, however, belong to the MRP area.

Create a corresponding MRP area segment in the material master record.

• Type 03 for Subcontractors

You define this kind of MRP area in the configuration activity Define MRP Areas for Subcontractors.

To define a new MRP area, proceed as follows:

1. In the MRP area overview, choose New Entries.
2. Enter a number and description for the MRP area. You can enter an alphanumeric number for the MRP area but it must contain at least five characters.
3. Enter the MRP area type, the plant and the receiving storage location (based on the MRP area type).
4. Navigate to the dependent view to define the dependent object for the relevant MRP area. Choose Plant to check the assignment of plants for the plant MRP area or choose Assign storage locations, if you want to define an MRP area of the type storage location.
5. Navigate to the dependent view to define the dependent object for the relevant MRP area. Choose Assign storage locations, if you want to define an MRP area of the type storage location.
6. You assign one or several storage locations to an MRP area of the type storage location.
7. Save the entries and choose Back.

If an MRP area is no longer required, you can delete it as follows:

• For MRP areas of the type Plant, delete the plant in the configuration activity Define, Copy, Delete, Check Plant. You can then delete the MRP area using this configuration activity.

• For MRP areas of the type Storage Location, check for material assignments by choosing Material Overview for MRP Area in the Details view for the MRP area that you want to delete. If material assignments exist, you must delete these assignments before you can delete the MRP area:

1. Set the Deletion Indicator for all material assignments of the MRP area using the Change Material app (view MRP1).
2. Use the Schedule Unassigning of MRP Areas app to delete all material assignments for which the deletion indicator is set.
3. Delete the MRP area using this configuration activity.

Note: If the MRP area that you want to delete has already been transported to your productive system, you must delete the material assignments both in the productive system and in the quality system.

• MRP areas of the type Subcontractor cannot be deleted using this configuration activity. Use the configuration activity Define MRP Areas for Subcontractors instead.

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 take the components that are required on the line.
