• What is the cause and solution for SAP error message BOM626 - Assembly for material &1, &2 already exists ?

  The SAP error message BOM626 indicates that there is an attempt to create a Bill of Materials (BOM) for a material that already has an existing assembly. This typically occurs when you try to create a new BOM for a material that already has a BOM defined in the system.
  Cause:
  
  Existing BOM: The primary cause of this error is that a BOM for the specified material and plant already exists in the system.
  Incorrect Data Entry: The user may have entered the wrong material number or plant, leading to confusion about whether a BOM exists.
  BOM Status: The existing BOM may be in a status that does not allow for the creation of a new BOM (e.g., it may be locked or marked for deletion).
  
  Solution:
  
  
  Check Existing BOM: 
  
  Use transaction code CS03 (Display BOM) to check if a BOM already exists for the specified material and plant. 
  If a BOM exists, you can either modify it or create a new version if necessary.
  
  
  
  Change BOM: 
  
  If you need to make changes to the existing BOM, you can use transaction code CS02 (Change BOM) to update the existing BOM instead of creating a new one.
  
  
  
  Delete or Archive BOM: 
  
  If the existing BOM is no longer needed, you can delete it using transaction code CS02 (Change BOM) and then select the delete option. Ensure that you have the necessary authorizations to perform this action.
  
  
  
  Create Alternative BOM: 
  
  If you need to maintain multiple BOMs for the same material, consider creating an alternative BOM by using the alternative BOM functionality in SAP.
  
  
  
  Check for BOM Status: 
  
  Ensure that the existing BOM is not in a status that prevents changes. If it is, you may need to change its status or unlock it.
