  The SAP error message /PLMI/GSS_R2B020 Synchronization unit for BOM &1 already exists typically occurs in the context of the SAP Product Lifecycle Management (PLM) module, particularly when dealing with Bill of Materials (BOM) synchronization. This error indicates that there is an attempt to create a synchronization unit for a BOM that already exists in the system.
  Cause:
  
  Duplicate Entry: The most common cause of this error is that a synchronization unit for the specified BOM already exists in the system. This can happen if there was a previous attempt to create the synchronization unit that was not properly completed or if the same BOM is being processed multiple times.
  System Configuration: There may be issues with the configuration of the PLM system or the BOM management settings that lead to this error.
  Data Integrity Issues: There could be inconsistencies in the data that are causing the system to believe that the synchronization unit already exists.
  
  Solution:
  
  
  Check Existing Synchronization Units: 
  
  Use transaction codes like CS03 (Display BOM) or CS02 (Change BOM) to check if the synchronization unit for the specified BOM already exists.
  If it does exist, you may need to review its status or determine if it can be reused instead of creating a new one.
  
  
  
  Delete or Modify Existing Unit: 
  
  If the existing synchronization unit is no longer needed, you may consider deleting it. However, ensure that this action does not affect other processes or data integrity.
  If the existing unit is valid, you may need to modify your process to utilize the existing synchronization unit instead of trying to create a new one.
  
  
  
  Review Logs and Messages:
