Nothing worse than a manager with little knowledge and no experience! The answer to your question is: if each view is involved in a transaction, then it should have its own business object. If some of the views are used for lookup purposes, then they should be included with the business object that uses them in the lookup. The first view that you add to your business object becomes your primary cursor, or the cursor that is acted upon. Eight business objects on a single form makes a very heavy form (Just ask Dr. Weieder about that!)

Regards!
