This error indicates that there are multiple entries in the payment file that have the same reference ID, which is not permitted.

  If necessary, modify the logic in the DMEE format to concatenate additional fields or use a different method to ensure uniqueness.
  
  
  
  Data Cleansing: If the duplicates are due to data issues, consider implementing data cleansing processes to remove or correct duplicate entries before they are processed.
  
  
  Testing: After making changes, test the payment file generation again to ensure that the error does not occur.
