Ivan,

>It's amazing the feeling of starting all over again. I'm a bit lost here. Ok, I set the relations between the bizobjs. In the child, use the bizobj builder and in the "Parent/Child Settings" filled the "Parent object" field. Now the child knows its parent. But how does it know the field in the parent DE used as reference ? It's tragic to have this kind of question, isn't it ? But it's fun, I'm laughing at myself a lot lately !

Were you able to figure this out? Mere Mortals business object classes have a cUniqueIDField property that can be examined by the Framework, or another business object to determine the primary key of a business object's data.

Regards,
