Modify Link Rule
The link rule defines how a connector treats an entity added as a link.
Adding a link with the ID or name rule forces the connector to retain the link’s ID or name even if that link entity no longer exists in the database. Adding a link with the at fe-realize rule ensures that each time a connector is realized the closest entity of the correct type is found and connected.
Update Link by Directly Editing Column Data in the Connector Browser
