I’m going to go out on a limb and guess that due to eCommerce Portal(I think thats what everyone has been calling it) no longer being available as a shopping cart app for navision we are to use Commerce Server and Biztalk going forward?
if you just want to use Navision without any modifications you have to go with BizTalk and the Commerce Server. However, there are other solutions available. But you need to do some modifications. osCommerce could be one solution for you. Reliable and easy to modify and therefore easy to implement with your existing Navision environment. You might have a look first. Then we can start a discussion about the implementation.
i believe you need this cart: http://www.shoppingcartelite.com it’s light and easy to modify.
