For the last few weeks I've been getting order routing error from Ariba, even though the orders are hitting my Netsuite. Anyone else running into this?
Are you utilizing the pre-configured SAP Ariba connector available in the marketplace? SAP Ariba typically anticipates a CXML in the return response, and these ready-made connectors are equipped with such responses.
I had the same thing happen. I had to create a brand new SAP Listener (not a clone). Then it started to send the correct server responses back to Ariba.
I just added another source in my flow with a new listener. Yes, you will need to get the new listener address and replace that in Ariba, so they send to the correct URL.
