Smart SAP Assistant

• What is the cause and solution for SAP error message MPE_PLAN_RTG_VERS013 - MBOM assignment of MBOM &1 already exists for routing &2 ?

  The SAP error message MPE_PLAN_RTG_VERS013 indicates that there is an attempt to assign a Multi-Level Bill of Materials (MBOM) to a routing that already has an existing assignment. This error typically occurs during the process of creating or modifying a routing in the SAP system when the system detects that the MBOM is already linked to the specified routing.
  Cause:
  The primary cause of this error is that the system has detected a duplicate assignment of the MBOM to the routing. This can happen due to:
  
  An attempt to assign the same MBOM to the same routing multiple times.
  A previous assignment that was not properly deleted or unassigned.
  Data inconsistencies or errors in the database.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing Assignments:
  
  Use transaction code CS03 (Display Material BOM) to check if the MBOM is already assigned to the routing. 
  Verify the routing using transaction code CA03 (Display Routing) to see if the MBOM is listed.
  
  
  
  Remove Duplicate Assignment:
  
  If you find that the MBOM is already assigned and you need to change it, you can either:
  
  Delete the existing assignment using transaction code CS02 (Change Material BOM) or CA02 (Change Routing).
  Unassign the MBOM from the routing if it is no longer needed.
  
  
  
  
  
  Create New Assignment:
  
  After ensuring that there are no duplicate assignments, you can proceed to assign the MBOM to the routing again using the appropriate transaction (e.g., CA01 for creating a routing).
  
  
  
  Check for Data Consistency:
  
  If the issue persists, consider running consistency checks or using transaction SE38 to execute relevant reports that can help identify inconsistencies in the BOM and routing assignments.
