• What is the cause and solution for SAP error message /PLMU/UI_GSS_2B001 - You cannot duplicate the BOM header ?

  The SAP error message /PLMU/UI_GSS_2B001 indicating "You cannot duplicate the BOM header" typically occurs when you are trying to create a Bill of Materials (BOM) that has a header that already exists in the system. This error is common in scenarios where the system is designed to prevent the creation of duplicate BOM headers for the same material and plant combination.
  Cause:
  
  Existing BOM Header: The most common cause is that a BOM header for the specified material and plant already exists in the system.
  Incorrect Data Entry: There may be a mistake in the data you are entering, such as the material number or plant code.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to view or modify existing BOMs, leading to confusion about whether a BOM already exists.
  
  Solution:
  
  
  Check Existing BOMs: 
  
  Use transaction code CS03 (Display BOM) to check if a BOM already exists for the material and plant you are trying to create.
  If it exists, you can either modify the existing BOM or create a new version if applicable.
  
  
  
  Correct Data Entry: 
  
  Ensure that you are entering the correct material number and plant code. Double-check for typos or incorrect entries.
  
  
  
  Use Different BOM Type: 
  
  If you need to create a different version of the BOM, consider using a different BOM type or a different validity period.
  
  
  
  Authorization Check: 
  
  Ensure that you have the necessary authorizations to view and create BOMs. If you suspect authorization issues, contact your SAP security team.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help files related to BOM creation for any specific guidelines or restrictions that may apply.
  
  
  
  SAP Notes: 
  
  Check for any relevant SAP Notes that may address this issue or provide additional guidance.
