  Adjust Configuration: If the target system's data model has changed, you may need to adjust the configuration of the migration tool to reflect these changes. This may involve updating the migration settings or using a different migration approach.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be guidelines or best practices for handling key fields during migration.
  Data Validation: Validate the data in the source system to ensure that it meets the requirements of the target system. This may involve cleaning up data or ensuring that all necessary key fields are populated.
