• What is the cause and solution for SAP error message /PLMB/BA_GSS202 - Synchronization unit &1 already exists ?

  The SAP error message /PLMB/BA_GSS202 Synchronization unit &1 already exists typically occurs in the context of the SAP PLM (Product Lifecycle Management) module, particularly when dealing with synchronization units in the system. This error indicates that there is an attempt to create a synchronization unit that already exists in the system.
  Cause:
  
  Duplicate Entry: The most common cause of this error is that a synchronization unit with the same identifier (denoted by &1 in the error message) already exists in the database.
  Data Migration or Import: If you are importing or migrating data, there may be a conflict with existing entries.
  Concurrent Processes: If multiple users or processes are trying to create the same synchronization unit simultaneously, this can lead to conflicts.
  
  Solution:
  
  
  Check Existing Synchronization Units: 
  
  Use transaction codes like /PLMB/BA_GSS or relevant PLM transactions to check if the synchronization unit already exists.
  If it does, you may need to use that existing unit instead of trying to create a new one.
  
  
  
  Modify the Identifier: 
  
  If you need to create a new synchronization unit, consider using a different identifier that does not conflict with existing entries.
  
  
  
  Data Cleanup: 
  
  If the existing synchronization unit is no longer needed, you may consider deleting it (ensure that this is in line with your organization's data management policies).
  
  
  
  Review Import/Export Processes: 
  
  If this error occurs during data import, review the data being imported to ensure there are no duplicates.
  Adjust the import logic to handle existing entries appropriately.
  
  
  
  Check for Concurrent Processes: 
  
  Ensure that no other users or processes are trying to create the same synchronization unit at the same time.
