  The SAP error message /PLMI/GSS_SI2B001 Synchronization unit already exists for the delivered planning scope typically occurs in the context of SAP Integrated Business Planning (IBP) or SAP S/4HANA when there is an attempt to create a synchronization unit that already exists for a specific planning scope. This can happen during the configuration or data integration processes.
  Cause:
  
  
  Duplicate Synchronization Unit: The error indicates that a synchronization unit with the same identifier already exists in the system for the specified planning scope. This can happen if:
  
  The synchronization unit was created previously and not deleted.
  There was an attempt to import or replicate data that includes a synchronization unit that already exists.
  
  
  
  Configuration Issues: There may be issues in the configuration settings where the same synchronization unit is being referenced multiple times.
  
  
  Data Import Errors: If you are importing data from an external source, the data might contain references to synchronization units that are already present in the system.
  
  
  Solution:
  
  
  Check Existing Synchronization Units: 
  
  Navigate to the relevant transaction or application in SAP where synchronization units are managed.

  Delete or Modify Existing Unit: 
  
  If the existing synchronization unit is no longer needed, consider deleting it.
  If it is needed, ensure that you are not trying to create a duplicate. You may need to adjust your planning scope or the parameters of the synchronization unit.
  
  
  
  Review Configuration: 
  
  Review the configuration settings for your planning scope and synchronization units to ensure there are no conflicts or misconfigurations.
