Thank you.

>A Biz object should model the business. If the business thinks of the header as being something different than the items. then you model it that way. If they think of a PO as a single object, you model it that way.

>>So far I have been creating one BIZ object for one table. But I am wondering if there is a better design for cases of parent/child tables and ancillary tables. For example, P.O. Header table and P.O. Item table. One approach I am considering is to instantiate P.O. items BIZ object in the INIT of the P.O. Header BIZ object. And then "deal" with any updates for P.O. Items within P.O. Header BiZ object. How do you design your BIZ objects for the cases of parent/child tables?

>>TIA.
