The Relationships pane displays the relationships in the selected scope, as they appear from left to right in the diagram. Select the relationship for an object in the Relationships pane to navigate to the object in the Diagram pane.
The list includes relationship chains, or composite relationships, such as Program[IsDefinedInCobol]Cobol[Includes]Copybook[GeneratesTargetXml]TargetXML. If you chose View > Potential Incomplete Composite Relationships when you drew the diagram, the list shows incomplete relationship chains, in which the final object in the chain is unresolved or otherwise unavailable.
