I am testing few interfaces with XI3.0 SP23 and R/3 4.7( 6.20 with XI add-on) .. All the outbound proxy interfaces uses static method of calling the proxy and so as the inbound proxy interfaces..
But one thing that puzzles me is that, for the outbound proxies, if I use sender XI adapter or not, the message is sent from R/3 using XI 3.0 protocol . But for inbound proxies, R/3 only accepts XI receiver adapter with XI2.0 protocol only.
Can you any explain please why this happens..detailed discussions are most welcome..I would appreciate replies with out links
please let me know if my question is not clear..
