  The SAP error message CS_VERSN_BOM001 indicates that a Bill of Materials (BOM) already exists for the specified material, plant, and other parameters. This error typically occurs when you attempt to create a new BOM for a material that already has an existing BOM in the system.
  Cause:
  
  Existing BOM: The primary cause of this error is that a BOM already exists for the specified material and plant combination.
  Incorrect Data Entry: You may have entered the material number, plant, or other parameters incorrectly, leading to a conflict with an existing BOM.
  Versioning Issues: If you are trying to create a new version of an existing BOM, the system may not allow it if the versioning settings are not configured correctly.
  
  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.
  
  
  
  Create a New Version:

  Correct Data Entry:
  
  Double-check the material number, plant, and other parameters you entered to ensure they are correct. If there is a typo or incorrect entry, correct it and try again.
  
  
  
  Delete or Change Existing BOM:
  
  If the existing BOM is no longer needed, you can delete it using transaction code CS02 (Change BOM) and then create a new BOM. Be cautious with this approach, as it may affect other processes.
  
  
  
  Consult Documentation:
