  If duplicates are found, you may need to delete the unnecessary records. Ensure that you have the necessary authorizations and that you are following your organization's data management policies.
  
  
  
  Review Data Upload Processes:
  
  If the error occurs during a data upload, review the data source to ensure that it does not contain duplicates.
