Hi Luis,

Looks like this is failing in the response mapping.

Could it be that the endpoint web service is returning a SOAP Fault which is why response is not being mapped.

Check if the web service is returning SOAP Fault if yes then add the fault mapping as well.

Kind Regards

I have seen your map and note that your problem probably is the SOAP VERSION. If your SOAP VERSION is 1.2. You will have to use java mapping to message transform.  Please (Marmota) confirm to discard this scenario.

Hi Mayimbu,

The issue is with the connection or response. The first error in your screenshot is soap response Unknown application error. Please check if the connection with web service is good and request message contains all the require fields.

The best way is to test the request message via SOAPUI or other external tools.

regards,

Harish

Hi Luis,

Check number 7 and question What should my web service return to the adapter? in this sap note 856597 - FAQ: XI 3.0 / PI 7.0/7.1/7.3 SOAP Adapter

HTTP/1.1 500 Internal Server Error
Content-Type: text/xml; charset="utf-8"

<SOAP:Envelope
  xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
  <SOAP:Body>
    <SOAP:Fault>
      <faultcode>SOAP:Server</faultcode>
      <faultstring>Server Error</faultstring>
      <detail>
        <e:myfaultdetails xmlns:e="Some-URI">
          <message>My application didn't work</message>
          <errorcode>1001</errorcode>
        </e:myfaultdetails>
      </detail>
    </SOAP:Fault>
  </SOAP:Body>
</SOAP:Envelope>

           will result in an application error message with fault payload


<e:myfaultdetails xmlns:e="Some-URI">
  <message>My application didn't work</message>
  <errorcode>1001</errorcode>
</e:myfaultdetails>

So in your case the web service is returning soap fault when you call the service and the payload is taking from detail tag of soap fault and you don't have mapping for fault payload that is why you are getting error Could not determine mapping steps for message 99745942-122d-11e6-a6a4-0000008e13ae.

If you receive proper response back then response mapping will be executed.

If your PI system is above or equal PI 7.31 SP09 the you can set TraceHTTP parameter in soap receiver adapter as shown in this blog then you will see the soap fault from the web service.

Praveen.

Hi Luis,

Following Praveen idea try to test with SOAPui and to check if you have any fault message. Also you can try to add the Parameter name = "XMBWS.NoSOAPIgnoreStatusCode", Parameter Value = true in the Module tab -> Module configuration.

Regards.
