Entity Subtypes

Design Phase Tasks	P	E	Scoping Objects
1. Promote subtype to entity type.	D	D	Parent entity type
2. Change subtype parent.	D A	D S	Old parent entity New parent entity
3. Add a new subtype to an existing entity type.	M	S	Parent entity type
4. Detail a partitioning.	M	S	Parent entity type
5. Transfer a relationship.	D D	S S	Two related entity types Plus entity type to transfer relationship to
6. Delete a subtype.	D	D	Parent entity type
7. Detail a subtype.	M	S	Parent entity type
8. Place unplaced subtype.	M	S	Parent entity type

Notes:

You want to include more of the data model (by scoping on other subject areas with Access, Short).
An attribute or relationship that is referenced in a view of an entity type cannot be deleted. The Objects Preventing Delete report identifies scoping objects define a subset that contains all references.
An entity type that is referenced in a view or in expected effects cannot be deleted.
You cannot add any new objects to a scoping object assigned Read protection.
You can add new items to the root subject area from this type of subset definition, because the root subset area is present with Access protection.

Note: All entity types must be free of Consistency Check errors before Transformation can succeed.
