When do you specify the data retention period in the SAP S/4HANA Migration Cockpit?

You specify the data retention period in the SAP S/4HANA Migration Cockpit when the project status is “Finished”. The data retention period is the length of time (in days) that the project and all associated data is kept in the system after you have set the status of the project to Finished. To do this, set the option Data Retention Period to On. The data will be deleted from the SAP S/4HANA system when the data retention time expires. If you set the option Data Retention Period to Off, then the project and all associated data will be kept in the system indefinitely. You can also change the retention time for finished projects on the Technical Information tab of the project settings. References = The Migration Project Screen, Migrating Data to the SAP S/4HANA System
