  Data Review: Review the source data for duplicates. Ensure that there are no two entries with the same name that are intended to map to different target values.
  Data Cleansing: Clean the data before migration. This may involve renaming duplicates or consolidating entries to ensure that each name is unique.
  Mapping Configuration: Check the mapping configuration in the migration tool. Ensure that the mapping logic correctly differentiates between entries and that it adheres to the target system's requirements.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration process you are using. There may be specific guidelines or best practices for handling such conflicts.
