ABAP-OO Workflow for PO-release

[Mike Pokraka]

Ah, for classes yes, but I was talking about extending existing BORs with
a class (this was Kietil's question). It's not as convenient as clicking
on a 'Create Subtype' button, you need to build the class from scratch. A
little extra effort but worthwhile in the long run.
Apologies for any confusion to those who misunderstood.
Cheers,
Mike
