Creating Web Service Proxy From WSDL - Error SPRX046

Question

We are attempting to create some Web Service proxy objects from some WSDL files. Some of the WSDL files contain message definitions with multiple parts such as
<i><wsdl:message name="GetNewSubmissionsResponse">
      <wsdl:part element="impl:Count" name="Count"/>
      <wsdl:part element="impl:MoreAvailable"       name="MoreAvailable"/>
      <wsdl:part element="impl:IRSData" name="IRSData"/>
      <wsdl:part element="impl:StateSubmissions" name="StateSubmissions"/>
   </wsdl:message></i>
This always generates the error message <b>SPRX046 - "
Msg Proxy generation terminated: Message must have exactly one part".</b>
Is this just a limitation with SAP Web AS? Has anyone dealt with this before? These WSDLs work in other environments (AXIS Java, XML Spy etc).
Thanks

It seems ABAP proxy only supports Document-Literal style WSDL. Document-literal style is supported by most Web services platforms, and is supposed to be most interoperable.
Per WS-I Basic Profile 1.0 (see [1])which provides interoperability guidance of using WSDL1.1, when the message part is defined using the @element attribute, the message can only be bound to so-called "document-Literal" style which in turn requires that the message contains only one part.The WSDL you provided violated the document-literal rules.
Have you tried to change the message definition a bit so it's BP conformant? Try defining a complex type for the subelements, then define an wrapper element to use that complex type, and finally let the message part to refer to the wrapper element. Something like,
<wsdl:message name="GetNewSubmissionsResponse">
<wsdl:part element="impl:GetNewSubmissionsResponseWrapper" name="myResponse"/>
</wsdl:message>
