Features of Business Content Objects 
The Business Content objects delivered by SAP are in the D version. If you want to work with the Content objects, you must transfer these from the D version into the A version.
From BW release 2.0A, active objects of Business Content no longer appear as SAP objects, but are used as customer objects.
A conversion program automatically converts Content objects from Release 1.2. All TADIR entries of active SAP Content objects are deleted. Old and new Content objects must then be assigned to a development class for the first transport.
