  Adjust Source Field Assignments: If multiple source fields are assigned to the target field, decide which source field should be used and remove the others from the mapping.
  
  
  Consult Documentation: Refer to the SAP documentation or guidelines for the specific data migration tool you are using to ensure that you are following the correct procedures for field mapping.
  
  
  Test the Changes: After making the necessary adjustments, test the mapping again to ensure that the error is resolved.
