We implemented a new more native integration between ECC and Ariba Sourcing in the 14s release. The flow is ECC RFQ to Ariba Sourcing Request. The Sourcing Buyer then approves the SR and creates the Sourcing Project. All items are passed from the ECC RFQ to the SR and then to the Sourcing Project. After awarding the event, the results can be sent back to a PO or an Outline agreement.
Check out the 14s Release materials in connect for more information.
