Timeout Error in a Synchronous XISOAP scenario

Hi All,

I have developed a Synchronous ABAP proxy to SOAP web service scenario.

ECC sends an ABAP proxy request to PI, PI forwards the request to the target system as SOAP message.

I have checked the interface via SOAP UI and it works fine but when we run the end-to-end flow it always ends with a Synchronous timeout error.

The Target system confirms that the response is sent from there side but in PI we are not receiving any response and the system throws a  timeout error.

As both PI and the Target system are in same Landscape there is no firewall in between.

Please suggest what can be the possible reasons and the approach to resolve the same?

Thanks in advance,
