• What is the cause and solution for SAP error message /ISDFPS/MM010 - Storage location &1 is already assigned to an MRP area ?

  The SAP error message /ISDFPS/MM010 Storage location &1 is already assigned to an MRP area indicates that the specified storage location (denoted by &1) is already linked to an MRP (Material Requirements Planning) area. This situation typically arises when you attempt to assign a storage location to an MRP area that is already associated with another MRP area.
  Cause:
  
  Duplicate Assignment: The storage location is already assigned to an existing MRP area, and SAP does not allow multiple MRP areas to share the same storage location.
  Configuration Error: There may be a misconfiguration in the MRP area settings or an attempt to reassign the storage location without first removing it from the existing MRP area.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing Assignments:
  
  Use transaction code MM02 (Change Material) or MM03 (Display Material) to check the current MRP area assignments for the material in question.
  Navigate to the MRP area view and verify which MRP area the storage location is currently assigned to.
  
  
  
  Remove Existing Assignment:
  
  If you need to assign the storage location to a different MRP area, you must first remove it from the existing MRP area.
  Use transaction code OMI4 (Maintain MRP Areas) to modify the MRP area settings and remove the storage location from the current MRP area.
  
  
  
  Reassign the Storage Location:
  
  After removing the storage location from the previous MRP area, you can now assign it to the desired MRP area using the same transaction (OMI4).
  
  
  
  Check for Errors:
  
  After making changes, ensure that there are no other errors or warnings in the system that might affect the MRP area configuration.
  
  
  
  Related Information:

  MM02: Change Material
  MM03: Display Material
