• What is the cause and solution for SAP error message /ISDFPS/MM020 - Cannot delete MRP area; MRP views exist ?

  The SAP error message /ISDFPS/MM020 Cannot delete MRP area; MRP views exist typically occurs when you attempt to delete an MRP (Material Requirements Planning) area that still has associated MRP views. This is a common issue in SAP when managing MRP areas, as the system enforces data integrity by preventing the deletion of MRP areas that are still in use.
  Cause:
  The error is caused by the existence of MRP views (such as MRP data, planning data, etc.) linked to the MRP area you are trying to delete. The system requires that all associated data be removed or deactivated before allowing the deletion of the MRP area.
  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Check MRP Views: 
  
  Navigate to the MRP area in question and check for any existing MRP views. You can do this by using transaction codes like MM02 (Change Material) or MM03 (Display Material) to view the material master data associated with the MRP area.
  
  
  
  Delete or Deactivate MRP Views:
  
  If you find MRP views associated with the MRP area, you will need to either delete or deactivate them. This can typically be done in the material master record by removing the MRP data for that specific MRP area.
  
  
  
  Use Transaction Code:
  
  You can use transaction code OMMR to manage MRP areas. Here, you can check the details of the MRP area and see if there are any views that need to be addressed.
  
  
  
  Delete MRP Area:
  
  Once all MRP views are removed or deactivated, you can proceed to delete the MRP area using the appropriate transaction code (like OMMR or OMM2).
  
  
  
  Check for Dependencies:
  
  Ensure that there are no other dependencies or configurations that might be preventing the deletion of the MRP area.
  
  
  
  Related Information:
  
  MRP Area: An MRP area is a subdivision of a plant that allows for more detailed planning and control of materials. It can be defined for specific storage locations, production lines, or other logical divisions within a plant.
  Material Master: The material master record contains all the information related to a material, including MRP data, which is crucial for planning and inventory management.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM01 (Create Material), MM02 (Change Material), MM03 (Display Material), and OMMR (Manage MRP Areas) for effective management of materials and MRP areas.
  
  By following these steps, you should be able to resolve the error and successfully delete the MRP area. If you continue to experience issues, consider consulting with your SAP administrator or support team for further assistance.
