You more than likely have the answer to this considering the timeframe that the question has been opened. Transporting BRF+ Objects in some cases is problematic due to the underlying Netweaver version and what mechanism is being used. Netweaver 7.3x does not perform a full transport of BRF+ objects, whereas Netweaver 7.4x does. What we have decided to do is to perform an export of the BRF+ Application from our development system and a corresponding Import on the QA System. This way all of the objects within that application are included.
