    copied!<p>I'm trying to consume a SAP Web Service from .NET via WCF. I've generated the proxy and I have configured the app.config file. </p> <p>Here is my test code:</p> <pre><code>WebServiceSAP.ZTEST_RFCClient myWCFService = new WebServiceSAP.ZTEST_RFCClient("MyEndPoint"); myWCFService.ClientCredentials.UserName.UserName = "&lt;UserName&gt;"; myWCFService.ClientCredentials.UserName.Password = "&lt;Password&gt;"; WebServiceSAP.ZTestRfc parameter = new WebServiceSAP.ZTestRfc(); parameter.TestInput = "This is a simple test"; WebServiceSAP.ZTestRfcResponse response = myWCFService.ZTestRfc(parameter); Console.WriteLine(reponse.TestOutput); Console.ReadLine(); </code></pre> <p>The ZTestRFC SAP method is a very simple function that accepts an input string, and outputs: <code>"Result: &lt;the input string&gt;"</code></p> <p>When I call ZTestRFC method, I got a null value in variable response. But SOAP messages seem to be fine.</p> <p><strong>SOAP Request</strong></p> <pre><code>&lt;MessageLogTraceRecord&gt; &lt;HttpRequest xmlns="http://schemas.microsoft.com/2004/06/ServiceModel/Management/MessageTrace"&gt; &lt;Method&gt;POST&lt;/Method&gt; &lt;QueryString&gt;&lt;/QueryString&gt; &lt;WebHeaders&gt; &lt;VsDebuggerCausalityData&gt;uIDPoxJmI5NcDatNiPM/wFAr52kAAAAAtqHAVnNWjEeMpMExOyr/vN7OXwCJZltNnikldpg5migACQAA&lt;/VsDebuggerCausalityData&gt; &lt;/WebHeaders&gt; &lt;/HttpRequest&gt; &lt;s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"&gt; &lt;s:Header&gt; &lt;Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none"&gt;urn:sap-com:document:sap:soap:functions:mc-style:ZTEST_RFC:ZTestRfcRequest&lt;/Action&gt; &lt;/s:Header&gt; &lt;s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt; &lt;ZTestRfc xmlns="urn:sap-com:document:sap:soap:functions:mc-style"&gt; &lt;TestInput xmlns=""&gt;This is a simple test&lt;/TestInput&gt; &lt;/ZTestRfc&gt; &lt;/s:Body&gt; &lt;/s:Envelope&gt; &lt;/MessageLogTraceRecord&gt; </code></pre> <p><strong>SOAP Response</strong></p> <pre><code>&lt;MessageLogTraceRecord&gt; &lt;HttpResponse xmlns="http://schemas.microsoft.com/2004/06/ServiceModel/Management/MessageTrace"&gt; &lt;StatusCode&gt;OK&lt;/StatusCode&gt; &lt;StatusDescription&gt;OK&lt;/StatusDescription&gt; &lt;WebHeaders&gt; &lt;Content-Length&gt;359&lt;/Content-Length&gt; &lt;Content-Type&gt;text/xml; charset=utf-8&lt;/Content-Type&gt; &lt;Set-Cookie&gt;MYSAPSSO2=AjExMDABAAxQMDEwMDA1MSAgICACAAMwNDADAAhEMTEgICAgIAQADDIwMTAxMTEwMTIwOQUABAAAAAgGAAFYCQABU%2f8A9jCB8wYJKoZIhvcNAQcCoIHlMIHiAgEBMQswCQYFKw4DAhoFADALBgkqhkiG9w0BBwExgcIwgb8CAQEwEzAOMQwwCgYDVQQDEwNQMTECAQAwCQYFKw4DAhoFAKBdMBgGCSqGSIb3DQEJAzELBgkqhkiG9w0BBwEwHAYJKoZIhvcNAQkFMQ8XDTEwMTExMDEyMDk0OFowIwYJKoZIhvcNAQkEMRYEFJC%2fNFLVBnu1ZAodWTlPApEs8sApMAkGByqGSM44BAMEMDAuAhUBS844BOB%2f8NgEGuepMgLaKbVEGGUCFQFLs6HiI%21BWT1MejMqvABd3%2fJFVMw%3d%3d; path=/; domain=.&lt;domain ... &gt;&lt;/Set-Cookie&gt; &lt;Server&gt;SAP NetWeaver Application Server / ABAP 700&lt;/Server&gt; &lt;/WebHeaders&gt; &lt;/HttpResponse&gt; &lt;SOAP-ENV:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"&gt; &lt;s:Header xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"&gt;&lt;/s:Header&gt; &lt;SOAP-ENV:Body&gt; &lt;rfc:ZTestRfcResult xmlns:rfc="urn:sap-com:document:sap:soap:functions:mc-style"&gt; &lt;TestOutput xmlns=""&gt;Result:&lt;/TestOutput&gt; &lt;/rfc:ZTestRfcResult&gt; &lt;/SOAP-ENV:Body&gt; &lt;/SOAP-ENV:Envelope&gt; &lt;/MessageLogTraceRecord&gt; </code></pre> <p>I don't know what could be happening.
