Hi Farhan - Do you guys think, its happening due to queue blockage? do we need to do some configuration, which might missed during the installation, because when our basis guy was installing the system, he got error in wizard, and skip that error, and later he did the manual configuration
>>>No. If it's an issue with the queue it should've been processed by PI/ atleast it would be in error state.
-----------------------------
However, If I am able to push the data to ECC by using asynchronous scenario(fie to proxy), then what is blocking me to update the response back to ECC in synchronous scenario.
>>>> Not sure but i suspect it's your proxy implementation. Earlier the direction was defined as "outbound" and later you changed it to "Inbound". May be you should regenerate the proxy.
Why don't you test this interface from SOAP UI and see if you get the response. you should use soap sender channel
same as below blog - in you case target system is also a web service..
