  The SAP error message CNV_20310_CHECK021 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that all provided source cost centers exist in the system, which may not be the expected condition for the migration process.
  Cause:
  
  
  Data Integrity Issues: The error suggests that the migration tool has detected that the cost centers you are trying to migrate already exist in the target system. This could be due to:
  
  Duplicate entries in the source data.
  Incorrect mapping of cost centers.
  The cost centers being created or modified in the target system after the migration data was prepared.
  
  
  
  Configuration Issues: There may be configuration settings in the migration tool that are not aligned with the current state of the target system.
  
  
  Solution:
  
  
  Review Source Data: Check the source data for duplicates or inconsistencies. Ensure that the cost centers you are trying to migrate do not already exist in the target system.
  
  
  Adjust Migration Mapping: If the cost centers are indeed supposed to be migrated, you may need to adjust the mapping or transformation rules in the migration tool to handle existing cost centers appropriately.
  
  
  Data Cleanup: If the cost centers in the source data are not needed, consider cleaning up the source data to remove any unnecessary or duplicate cost centers.
  
  
  Check Target System: Verify the target system to ensure that the cost centers are in the expected state. If they should not exist, you may need to delete or deactivate them before proceeding with the migration.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be specific guidelines or best practices for handling existing data.
  
  
  Error Handling: Implement error handling in your migration process to manage situations where existing data conflicts arise.
