  Delete Assignment of a Material to an MRP Area

If you delete the assignment of a material to an MRP area in an ERP or R/3 system by setting a deletion flag, this has the following consequences:

In the ERP or R/3 system, the material is then automatically planned at plant level. All receipts, requirements, and stocks of the material that were previously assigned to the MRP area are automatically assigned to the plant. In SAP APO, this is not the case. In SAP APO, all MRP elements and stocks remain assigned to the MRP area.

How to rectify this inconsistency is explained using orders as an example:

  1. You must manually delete the orders in the location of the MRP area in SAP APO.

  2. You must then likewise manually delete the location product for the MRP area in SAP APO.

  3. You must now carry out an initial transfer for the orders from the R/3 or ERP system. Alternatively, you can also run the report CIF Comparison/Reconciliation of Transaction Data (transaction /SAPAPO/CCR) in SAP APO.

    Caution Caution

    As a general rule, in the case of all changes that you make to MRP areas in the R/3 or ERP systems (such as assigning a storage location or a material to a different MRP area) the transaction data in the R/3 or ERP system is automatically adjusted to the changed situation. However, this adjustment does not take place in SAP APO. After making a change, you must first transfer the changed master data to SAP APO. You can then adjust the transaction data in line with the changed situation using the report CIF Comparison/Reconciliation of Transaction Data (transaction /SAPAPO/CCR).

    End of the caution.
