  The SAP error message CNV_21539015 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This specific error indicates that there is an issue with the attendance or absence types being processed, where the old and new types are found to be identical.
  Cause:
  The error message CNV_21539015 arises when the system detects that the old attendance/absence type and the new attendance/absence type are the same. This can happen due to:
  
  Data Mapping Issues: During the migration process, the mapping of old attendance/absence types to new ones may have been incorrectly configured, leading to a situation where the same type is being mapped to itself.
  Duplicate Entries: There may be duplicate entries in the data being migrated, causing the system to interpret that the same type is being processed for both old and new.
  Configuration Errors: There might be a misconfiguration in the system settings or in the migration tool that leads to this error.
  
  Solution:
  To resolve the CNV_21539015 error, you can take the following steps:
  
  
  Review Mapping Configuration: Check the mapping configuration for attendance and absence types in the migration tool. Ensure that each old type is mapped to a distinct new type and that there are no identical mappings.
  
  
  Data Validation: Validate the data being migrated to ensure there are no duplicates or incorrect entries. You may need to clean up the data before attempting the migration again.
  
  
  Consult Documentation: Refer to the SAP documentation or migration guides related to the specific migration process you are using. There may be specific instructions or considerations for handling attendance and absence types.
  
  
  Test Migration: If possible, perform a test migration with a smaller dataset to identify if the issue persists. This can help isolate the problem without affecting the entire dataset.
  
  
  Seek Support: If the issue cannot be resolved through the above steps, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific system configuration and migration scenario.
