E9001 - TRA_TransferNoLink

At runtime, the following error can be displayed:

E9001 - TRA_TransferNoLink: The Transfer card has not been correctly set-up. Please specify a link on the transfer card.

This error indicates that the section Table Link (key fields) is empty. In order to fix it, you would need to populate this section with the primary keys (PKs) from source and destination systems. Once you have added the primary keys, save the changes and run the transfer again.
