Missing response message in Idoc - WS scenario

Question

Hello
I 'm missing a response message in the follwing scenario:
Idoc-> XI -> Web service (SOAP)
A Matmas idoc is sent from R/3 to XI. In XI the Idoc is
mapped to a SOAP message and sent to a web service.
The Message Interface for the SOAP call is synchronous
and has a PushMaterialSoapOut and a PushMaterialSoapIn
messsage, which is defined in the WSDL from the
web service and imported into XI Repository.
Everything is working fine but I do not get the response
message. The web service has sent the response message. I
have traced the firewall logs and i have seen the
response.
What is wrong? Is it basically possible to have a
scenario like this?
The message must have arrived somewhere, since the web
server does not throw an exception. But where is it?
Thank you in advance
Thomas

Ok, so I have to use BPM.

I was thinking about an ALEAUD idoc which is sent back
to R/3. Therefor I have created an synchronous message
interface with the MATMAS idoc as outgoing message and an
ALEAUD as incoming message. Accordingly I have a message
mapping for the response message.
An other reaction to the response message could be to set
the message to status failed. But this is the next issue.

The process in SAP R/3 is fixed. To move to BAPI is not
an option.
