Okay, it seems I have not been quite clear so I'll try again. Thansk for your patience.
What I want to achieve is exactly what I see in the CRM application where the BO Customer can display related records from the BO Group Communications.
In my application, in CRM terms, I established the BO Group Communications and created an attribute in the Customer BO named Communications of type Communications and related it with the Attribute Customer (called Correspondent in CRM). This is the same as the CRM application. When I place the Communication attribute on a form section, it produces no data. I see the list frame but within it it just says "No Data to Display".
Do I need to establish other relationships to accomplish this?
