The data retention period in the SAP S/4HANA Migration Cockpit is typically specified when the project status is "Finished." At this point, the migration project has been completed, and specifying the data retention period helps determine how long the migrated data and logs should be retained for auditability, traceability, and compliance purposes. Setting this period ensures that data is managed according to organizational policies and regulatory requirements while optimizing storage and system performance.
