Activate, deactivate, or delete relations
Any of the relations within a relation set can be activated or deactivated at any time. When deactivated, a relation remains within its relation set, but takes no part in the solution next time the relation set is solved.
To quickly activate or deactivate a relation, select or deselect it in the Relation Detail Browser. The third and fourth relations are deactivated here:
A deactivated relation is indicated by grey text and Unsolved status in the Relations browser. A relation deactivated by the system because of a missing reference element is indicated as Incomplete in the Status column, as shown above.
