Commerce Gateway do I need it?

We are currently looking at starting a B to B integration initially for Purchase orders using Navision and BizTalk.

What I’m confused about is the role of the commerce gateway. We already have the application builder so we can use the xml dataports and from what I understand that is all I need as an input into Biztalk.

What additional functionality does commerce give, and is it worth the extra money?

Thanks in advance,

Andy

You don’t need Commerce Gateway to use BizTalk, you don’t even need BizTalk, and you can use other package with the similar features.
The biggest advantage of using Commerce Gateway it’s having already an infrastructure of importing and exporting data to BizTalk. The only thing you have to do is mapping your Navision file to your’s partner file. If you don’t use Commerce Gateway then you have to do all the coding of detecting if a file is in a folder and all that stuff.
