Hi, I have a virtual service (for a real SOAP web service) set up on a VSE server and run it through a Live System successfully. Now I want to add more request/response pairs into the knowledge base so it behaves more like real service. From the user's guide of DevTest solution, I saw a Learning mode which seems to be right one but I don't see this option in the selection list. The available selections include 1) Most Efficient, 2) Transaction Tracking, 3) Live System 4) Image Validation, and 5) Dynamic. How can we set up the virtual service so that it can record more request/repose pairs and use them in its knowledge base? Thanks.
