This error indicates that there is an attempt to create or register a synchronization unit version that already exists in the system.
  Cause:
  
  Duplicate Entry: The most common cause of this error is that a synchronization unit with the specified version already exists in the system. This can happen if there was an attempt to create a synchronization unit with the same version number without first deleting or modifying the existing one.
  System Configuration Issues: There may be inconsistencies in the system configuration or metadata that lead to this error.

  Solution:
  
  
  Check Existing Synchronization Units:

  Identify if the version you are trying to create already exists.
  
  
  
  Modify or Delete Existing Version:
  
  If the version already exists and you need to create a new one, consider modifying the existing synchronization unit or deleting it if it is no longer needed.
  Ensure that you have the necessary authorizations to perform these actions.
  
  
  
  Use a Different Version Number:
  
  If you are creating a new synchronization unit, consider using a different version number that does not conflict with existing entries.
  
  
  
  Check for Concurrent Processes:
  
  Ensure that no other processes are trying to create or modify synchronization units at the same time. If necessary, coordinate with other users or processes to avoid conflicts.
