We are building Level 2 (i.e. product level) punchout into our supplier application. We've run into a challenge with no solution in the Ariba's documentation. Specifically, after we return an OrderMessage that populates the Ariba cart with an item, what if the buyer decides they do not want the item? How do they remove it from Ariba and how is that communicated back to the supplier system? While we find Ariba supports "edit" and "inspect" setup requests for punching back into an item, there is no "delete" request. A little background might help here. In our punchout architecture, we are populating a cart in our application that mirrors the cart generated in Ariba. In order to keep them in sync,we need a way to remove items from our cart. But in Level 2 punchout, the buyer never sees the supplier cart (only the Ariba cart). Unfortunately, using an "edit" request and setting the item quantity to zero (0) does not work in our application - all quantities must by >= 1. Perhaps when items are removed from the Ariba cart, they are simply not included in the OrderRequest communication, which should be our signal to remove any missing items from our cart?
Anyone out there run into this before? Have I missed an Ariba cXML communication that does this?
Thanks!
