  Data Validation: Ensure that the data being migrated meets the validation rules of the target SAP system. Cleanse the data in the source system if necessary.
  Mapping Review: Verify the mapping of fields between the source and target systems to ensure that data is being transferred correctly.
  Duplicate Handling: Implement logic to handle duplicates appropriately, either by merging records or by ensuring that unique constraints are respected.
  Testing: Conduct thorough testing of the migration process in a non-production environment to identify and resolve issues before executing in the live system.
