Question

I am calling a SAP webservice(HTTPS) in BizTalk 2010. I have generated schema using consume wcf service wizard. When I call the webservice by passing the requested schema instance, I receive following fault message:

<SOAP:Fault xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
      <faultcode>SOAP:Server</faultcode>
      <faultstring>Server Error</faultstring>
      <detail>
        <s:SystemError xmlns:s="http://sap.com/xi/WebService/xi2.0">

          ]]></text>
        </s:SystemError>
      </detail>
    </SOAP:Fault>

I have tried calling webservice using SOAPUI tool and I receive a proper response. I traced the request going out from BizTalk sendPort (calling webservice overHTTP-soap using wcfBasicHTTP binding) using fiddler, the request looks fine and works in SOAPUI. I have no clue about why I receive this particular soap fault in BizTalk.
Any help is appreciated
Thanks.

The issue has been resolved. I modified the url of the endpoint to one that was used by SOAPUI.
