Example: MRP for Two Storage Locations 
Using an MRP area, you can group two storage locations into one MRP area which means that you can plan and procure materials for these two storage locations separately from your planning at plant level.
Example data:
- Materials A, B, and C are stored in storage locations 0001 and 0002 and are withdrawn for production. They are planned using reorder point planning. Both storage locations are to be planned together. Storage location 0001 is the receipt storage location for the procurement elements.
Prerequisites
- In Customizing for MRP, you created an MRP area, type storage location for the two storage locations 0001 and 0002 which you assigned to the storage locations.
- You assigned this MRP area to the material master records of materials A, B and C by creating an MRP segment. In the MRP segment, you entered the storage location 0001 in the External procurement storage location as this is also the receipt storage location for the components.
Procedure in planning
In the planning run, the system checks the stock in storage location 0001 and0 002 for each material. If the stock level falls below the available stock (=total available stock in both storage locations), the system creates a procurement element for the replenishment quantity.
When determining the procurement elements for B and C, the system reads the external procurement storage location and uses this as the receipt storage location. This is storage location 0001. This means the procurement elements of the MRP area you created for storage locations 0001 and 0002 are assigned to storage location 0001.
