In the original system, you can restore 3.x DataSources from DataSources that were migrated in the standard way (SAP source system, file, DB Connect). With a transport operation, you restore the 3.x DataSource in the target system as well.
Only use this function if unexpected problems occur with the new data flow after migration and these problems can only be solved by restoring the data flow used previously.
Furthermore, you can use this function to undo a replication to the incorrect object type (R3TR RSDS).
For file source system and DB Connect: You exported and archived the relevant 3.x objects when you migrated the 3.x DataSource.
...
1. In the maintenance screen of the DataSource (transaction RSDS) in the original system (development system), choose DataSource → Restore 3.x DataSource.
2. Enter a transport request.
3. If required, delete the dependent transformation (R3TR TRFN) and data transfer process (R3TR DTPA) objects.
4. Transport the restored 3.x DataSource (R3TR ISFS), along with its dependent objects, into the target system.
