• What is the cause and solution for SAP error message MPE_BOM_INVERSION003 - Material already exists ?

  The SAP error message MPE_BOM_INVERSION003 ("Material already exists") typically occurs when you are trying to create or modify a Bill of Materials (BOM) for a material that already has an existing BOM in the system. This can happen in various scenarios, such as when you attempt to create a new BOM for a material that already has one defined, or when you are trying to copy a BOM and the target material already has a BOM.
  Cause:
  
  Existing BOM: The primary cause of this error is that the material you are trying to create or modify already has an associated BOM in the system.
  Incorrect Data Entry: Sometimes, the error can arise from incorrect data entry or selection of the material number.
  BOM Status: The existing BOM might be in a status that does not allow for modifications or duplications.
  
  Solution:
  
  
  Check Existing BOM: 
  
  Use transaction code CS03 (Display BOM) to check if a BOM already exists for the material in question. If it does, you can either modify the existing BOM or delete it if it is no longer needed.
  
  
  
  Modify Existing BOM: 
  
  If you need to make changes, you can use transaction code CS02 (Change BOM) to modify the existing BOM instead of creating a new one.
  
  
  
  Delete Existing BOM: 
  
  If the existing BOM is not needed, you can delete it using transaction code CS02 (Change BOM) and then select the delete option.
  
  
  
  Use Different Material: 
  
  If you intended to create a BOM for a different material, ensure that you are using the correct material number.
  
  
  
  Check BOM Status: 
  
  Ensure that the existing BOM is in a status that allows for changes. If it is locked or in a status that prevents modifications, you may need to change its status.
  
  
  
  Related Information:
  
  BOM Types: Understand the different types of BOMs (e.g., production BOM, sales BOM, etc.) and their specific requirements.
  Transaction Codes:
  
  CS01: Create BOM
  CS02: Change BOM
  CS03: Display BOM
  CS11: Display BOM for a material
  
  
  Authorization: Ensure that you have the necessary authorizations to create or modify BOMs in the system.
