  Review the transformation rules to see if they are set up correctly and if they are supposed to allow duplicates.
  
  
  
  Modify Data Source: 
  
  If duplicates are found in the data source, you may need to clean the data by removing or consolidating duplicate records before they are processed by the transformation.
  
  
  
  Adjust Transformation Rules: 
  
  If the transformation rules are incorrectly configured, adjust them to ensure that they correctly handle the data without creating duplicates.
  Ensure that the key fields defined in the transformation are appropriate and that they uniquely identify each record.
  
  
  
  Testing: 
  
  After making changes, test the transformation process again to ensure that the error is resolved and that the data is processed correctly.
