Adapter module selection in NWDS

Hi All,

I am working on a prototype for B2B using PO Netweaver 7.4 and I'm noticing one difference between NWDS and the swing client and was wondering if anyone else has had experience with it.  Here is the module selection in NWDS:

Here is the matching module configuration tab for the same channel in the swing client:

I'm trying to understand why the B2B adapter modules are not available for selection when working in NWDS.  Is anyone familiar with what controls this list selection in NWDS?

Regards,
