  The SAP error message CNV_21522015, which states "Old and new employee subgroups &1 are identical," typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that the system has detected that the employee subgroup being migrated or converted has not changed; the old and new values are the same.
  Cause:
  
  No Change in Subgroup: The primary cause of this error is that the employee subgroup for a specific employee is being updated to the same value it already has. This can happen if the migration data is incorrectly prepared or if there is a misunderstanding of the data that needs to be changed.
  Data Preparation Issues: The data extraction or transformation process may not have been executed correctly, leading to the same subgroup being assigned to both the old and new records.
  
  Solution:
  
  Review Migration Data: Check the data being used for the migration. Ensure that the old and new employee subgroup values are indeed different. If they are the same, you may need to adjust the data to reflect the intended changes.
  Data Mapping: Verify the mapping of employee subgroups in your migration template or tool. Ensure that the mapping logic is correctly set up to reflect the intended changes.
  Filter Out Unchanged Records: If certain records do not require any changes (i.e., the subgroup remains the same), consider filtering them out from the migration process to avoid this error.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool you are using for any additional guidance or best practices.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might provide additional context or solutions for this error. SAP Notes can often provide patches or updates that address specific issues.
  Migration Cockpit: If you are using the SAP S/4HANA Migration Cockpit, familiarize yourself with its functionalities and how it handles employee subgroup changes.
  Testing: Before executing a full migration, conduct a test migration with a subset of data to identify and resolve any issues without impacting the entire dataset.
  
  By addressing the root cause of the error and ensuring that the migration data is correctly prepared, you should be able to resolve the CNV_21522015 error effectively.
