Process Timeout is not working in BPM process in a Request-Reply Scenario


I have a BPM process which is designed on Request-Reply basis. I need to provide a time out for the BPM process but thats not working. There are no errors and it gets sucessfully deployed in the Server. But if I invoke the BPM Request step externally through a flow service the flow service doesn’t complete. It keeps running providing no response back. If I use step time out on a particular step in BPM process that works, even if the BPM process is invoked from a flow service. I get the response back from the BPM Process.

Software tool which i am using is Software AG 8 SP1.

Please provide a solution for this or a FIX if any.

Thank you,
