I have written a odata service in recently installed gateway system which is SAP NETWEAVER VERSION 7.4 SP8. After registering the service when I tried to open the SAP Gateway client I couldnt find any session opened. When tried to click SAP Gateway client couple of times , I see a popup saying that the maximum GUI sessions have exceeded.But I dont find those many sessions opened.What could be the issue ? Could anybody please help me out here!!
