Issue: Not able to set add resources using drag-and-drop.
Solution: Ensure that you are dropping the resources to correct targets and to solution editor links instead of Mapping Group to Deployment Profile links. You can add physical resources only to the Deployment Profile view. The Big Data System and Teradata are target only databases. You can drag-and-drop target only databases as a source database in the mapping editor. This is possible as mapping is a logical concept and no check is performed by Oracle GoldenGate Studio.
