Outbound Proxy - only system error (cx_ai_system_fault thrown) on Soap Fault

Hi all,

I have a ERP (outbound proxy) --> PI --> 3rd party webservice scenario.

The 3rd party sends a soap fault back if something went wrong (e.g. not found, wrong parameters, etc)

The soap fault looks like this and the HTTP code sent is 200

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">   <soap:Body>      <soap:Fault>         <faultcode>soap:Server</faultcode>         <faultstring>1002: SearchFor or LastId Invalid</faultstring>         <detail>Cause: The SearchFor or LastId parameter was not recognised.
Resolution:Check the documentation for valid options.</detail>      </soap:Fault>   </soap:Body></soap:Envelope>

Problem is that cx_ai_system_fault does not give back a meaningful error. Only "PARSING.GENERAL" and I have to look to SXMB_MONI to get the real reason.

Any ideas how to overcome?

Thx

Jens
