Peter,

I totally agree with you. Allowing Fk references from outside of the schema is inviting confusion, duplication and disaster. There is really no good reason for it.

Whoa there everybody!

While the answer is quite correct, of course (I read the FM years ago), what has not been raised is the danger of allowing reference to multiply unhindered across numerous schemas.

Be very careful if you choose to do this, otherwise, without a little care, you may manage to lock your entire database solid with conflicting FKs!

We did, learned our lesson, and now reference is ONLY permitted within the one corporate schema.
