  Removing Duplicates: If duplicates are not needed, you can remove them from the source data.
  Merging Records: If the duplicates contain different information, you may need to merge them into a single record that retains all necessary information.
  Adjusting Mapping: If the duplicates are valid and should be retained, you may need to adjust the mapping or transformation rules to accommodate them.
