Dear Gurus,
I have developed one integration scenario which is proxy to soap. When i test this proxy it gives me error 
I have check the connection.Connection is fine between ourPi system adn PI system of other party Some blogs said it could be connection or port issue. I have telnet that and from connection perspective everything seems to be fine. Some blog said that it could be issue of role "SAP_XI_IS_SERV_USER". The other side also have added this role in their PI login, the one we are using in our SOAP receiver channel. But problem is still there. can anybody help what could be the problem.
Thanks
regards
imran
