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.
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.
Has anyone done an integration with NetSuite and SharePoint? I am looking to export NetSuite CSV files into a SharePoint document library. Not sure where to start or if this is possible.
