Reg: Commerce Portal & Commerce Gateway

Hi all, Thanks in advance. I need to have more clarity in terms of the functionalities of commerce portal(CP) and Commerce Gateway(CG). Where should I suggest CP and CG ? Are they dependent on each other in any cases ? Is it possible to do an EDI through CP or CG ? … can any one please detail on this … Thanks again. Regards,

CP is the online store that connects to Navision. CG is the B2B functionality, which works through Biztalk. If you want to do EDI, then Commerce Gateway would be a candidate, Commerce Portal definately not.
