SAP Ariba Interface

We are looking to integrate Ariba & Coupa.  Have you had any luck getting this accomplished?

we would be interested in integrating with both Ariba and Coupa. We have TrueCommerce EDI that is offering to build the integration for us, but there must be a more direct and less expensive way.

Same here, we have multiple Payment Portals with Ariba being the largest that we would like to get integrated with to streamline Customer PO entry and Invoicing (among other things).
