Has anybody built a validation rule to prevent duplicate purchase order numbers from being used? If so, care to share how you did that?

Looks like all I have to do is create a Validation Rule with this criteria:

(PO Number is not unique) AND (<Initiator>.Interactive equals 'True')

Borrowed this from the Asset object type which I knew to enforce uniqueness.
