SAP unable to receive response message from webmethods in a Synchronous RFC Call

SAP invokes a Synchronous RFC and also passes data to webMethods.The webMethods is supposed to send RETURN structure back to SAP.From webMethods,there is a listener notification that listens for data from SAP and invokes a service to process the data .After the successful execution of service,
webMethods sends a “success” type response message to SAP.When I analyse the logs,I could see RFC being invoked successfully and also sending response back to SAP.But SAP is not receiving response message from webMethods.
Both SAP and webMethods are “uni-code” enabled .
Please let me know if anyone faced a problem in sending back response to SAP
in a synchronous RFC call

Can you create an RFC trace of the situation?

Did you find a solution to this issue? I am facing the same issue

In this case: attach an RFC trace of one sample execution here…
Also a new_sap.log with log level 8 could help.
