This error indicates that the system has detected that the source data and the target data are the same, making any changes to the source data redundant.

  Verify Data: Check the source and target data to confirm whether they are indeed identical. If they are, no action is needed, as the system is functioning correctly.
  
  
  Update Source Data: If you intended to change the source data, ensure that the changes are made before attempting to transfer or update the data again.

  Check for Data Integrity: Investigate any potential data integrity issues. Ensure that the data in the source system is up-to-date and accurately reflects the intended changes.
