  Update MRP Area Configuration: If the assignment needs to be changed, ensure that the MRP area configuration allows for such changes. You may need to consult with your SAP configuration team to ensure that the settings are correct.
  
  
  Use Transaction Codes: Use transaction codes like OMD0 (Define MRP Areas) to manage MRP area settings and ensure that the storage location assignments are correct.
