Object Requires Existence of Related Object

The related object in the message is actually an enabling object. Something that had to be present in the destination model for the migration to produce a valid model was missing. Usually this indicates that the parent object of the object in the message was missing. At other times, the aggregated object references the object that is listed.

For example, the migration of Entity Type Order fails if the Subject Area that contains Order does not exist in the destination model. If the Subject Area is migrated simultaneously as the Entity Type, the migration succeeds. The migration of a Navigation Diagram fails if all the Windows, Dialog Boxes, and Procedure Steps that are referenced by the Navigation Diagram do not exist in the destination model. The migration succeeds if all these referenced objects are present.

This message can also indicate that the enabling objects do not have common ancestry between the models.
