If I understand you correctly, you want to have two reference fields (one in class BusinessPartner, the other in class Customer) to be controlled from one database column (in the CUSTOMER table). I do not think that OJB can do that automatically. You may, of course, obtain the customer(s) referencing a given BusinessPartner by a suitable OJB query. If you want to do that transparently, you could do that query in instance callbacks. Of course, this is an intrusive way to do it.
