• What is the cause and solution for SAP error message /PLMI/AL_GSS023 - Material BOM &1 already exists ?

  The SAP error message /PLMI/AL_GSS023 Material BOM &1 already exists indicates that you are trying to create a Bill of Materials (BOM) for a material that already has an existing BOM in the system. This error typically occurs in the context of BOM management within the SAP system.
  Cause:
  
  Existing BOM: The primary cause of this error is that a BOM for the specified material already exists in the system. Each material can only have one active BOM at a time.
  Incorrect Data Entry: There may be a mistake in the material number or plant code you are using, leading to confusion about whether a BOM exists.
  Different BOM Usage: The existing BOM might be for a different usage (e.g., production, engineering, etc.), and you are trying to create a new one without specifying the correct usage.
  
  Solution:
  
  
  Check Existing BOM: 
  
  Use transaction code CS03 (Display BOM) to check if a BOM already exists for the material in question. Enter the material number and the plant to see the details.
  
  
  
  Modify Existing BOM: 
  
  If a BOM already exists and you need to make changes, you can use transaction code CS02 (Change BOM) to modify the existing BOM instead of creating a new one.
  
  
  
  Create Alternative BOM: 
  
  If you need to create a new BOM for a different usage or version, ensure you specify the correct BOM usage and status. You can do this using transaction code CS01 (Create BOM) and selecting the appropriate usage.
  
  
  
  Check for Deletion Flags: 
  
  If you believe the BOM should not exist, check if it has been flagged for deletion. You can do this in the BOM display transaction (CS03).
  
  
  
  Consult Documentation: 
  
  Review the SAP documentation or your organization's BOM management guidelines to ensure you are following the correct procedures.

  CS01: Create BOM
