• What is the cause and solution for SAP error message CNV_21523015 - For personnel area &1, old and new personnel subareas &2 are identical ?

  The SAP error message CNV_21523015 indicates that there is an issue with the personnel area and personnel subareas during a data migration or conversion process. Specifically, the error states that for the specified personnel area, the old and new personnel subareas are identical, which is not allowed in the context of the operation being performed.
  Cause:
  This error typically occurs during data migration or conversion activities, such as when using the SAP S/4HANA Migration Cockpit or other data transfer tools. The cause of the error is that the system is trying to map an old personnel subarea to a new personnel subarea, but both are the same. This can happen due to:
  
  Incorrect Mapping: The mapping configuration may have been set up incorrectly, leading to the same subarea being assigned as both old and new.
  Data Duplication: There may be duplicate entries in the data being migrated, causing the system to interpret them as identical.
  Configuration Issues: There may be issues in the configuration of personnel areas and subareas in the SAP system.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Mapping Configuration: Review the mapping configuration for the personnel areas and subareas in the migration tool you are using. Ensure that the old and new personnel subareas are correctly defined and that they are not set to be the same.
  
  
  Data Validation: Validate the data being migrated to ensure that there are no duplicates or incorrect entries. You may need to clean up the data before attempting the migration again.
  
  
  Adjust Personnel Subareas: If the old and new personnel subareas are indeed meant to be different, adjust the mapping accordingly. If they are meant to be the same, you may need to reconsider the migration strategy or the necessity of the change.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using for any additional guidelines or troubleshooting steps.
