Inbound proxy with SOAP receiver channel is not worlinng in AAE, PI 7.3

Hi All,

I am working on PI 7.3 which has both java and abap stack, my scenario is synchronous Soap-PI-Soap…

We have sender portal and receiver ECC(synch proxies). There is no mapping transformation and we want to use AAE. If we don’t use AAE and go with the regular configuration as creating sender receiver agreement and interface and receiver determination…taking XI adapter at receiver side, then things are working fine. Messages are successfully flowing.

Instead that if we use AAE, messages are failing at adaper engine, I can see error at communication channel "SOAP: error occured:
com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.aii.af.sdk.xi.srt.BubbleException: HTTP Response Received. Status Code = 500 [null "null"]"

what additional configurations are required? I have created a G type connection taking the path prefix as “/XISOAPAdapter/MessageServlet?ximessage=true” and used the same in SXMB_ADM.

Is there any configuration required at PI NWA related to JCO RFC provider? Or any destination needs to be maintained there?

Please suggest.

Thanks
