This can occur in scenarios where multiple users or processes are trying to create or modify PBOMs simultaneously, or if there is a misunderstanding about the current state of the PBOMs in the system.
  Cause:
  
  Existing Active PBOM: The primary cause of this error is that there is already an active PBOM for the specified material, plant, and counterparty combination.
  Concurrency Issues: Multiple users or processes may be trying to create or modify the same PBOM at the same time.
  Data Integrity Issues: There may be inconsistencies in the data, such as orphaned records or incorrect status flags.
  
  Solution:
  
  
  Check Existing PBOMs: 
  
  Use transaction codes like CS03 (Display Material BOM) or CS02 (Change Material BOM) to check if an active PBOM already exists for the specified material, plant, and counterparty.

  Modify or Delete Existing PBOM:
  
  If the existing PBOM is valid and needs to be updated, you can modify it using the appropriate transaction code.
  If the existing PBOM is no longer required, you can delete it using CS02 or CS05 (Delete Material BOM).
  
  
  
  Review User Access and Processes:
  
  Ensure that users are aware of the current state of PBOMs to avoid concurrent modifications.
