After Removing an Origin Target Version

If you remove an object version from the TargetVersions collection of a delete-propagating destination relationship, Repository considers performing a propagated deletion.

Delete propagation always occurs from the origin object toward a destination object. Thus, in this situation, Repository considers performing a propagated deletion on the object version that was the source of the relationship whose TargetVersions collection you modified. Repository performs a propagated deletion on the source object version if all of the following conditions hold:

• The item you removed was the last item in its TargetVersions collection.
  
  
• The source object version has no other destination relationship of the same type as the destination relationship whose TargetVersions collection you modified.
  
  
• The source object satisfies the basic requirements for object-version deletion. (See Requirements for Object-Version Deletion.)
