RPC/Encoded SOAP Response Generation in SAP PI

Hi All,

For our client, we are currently migrating interfaces from IBM WPS to SAP PI 7.31 (Single Stack). In some of our interfaces, we currently have a synchronous SOAP to RFC scenario. What we see in current WPS set up is that the SOAP request and response style in not Document/Literal (out of the box supported by SAP PI) but instead its RPC/Encoded. Also, the SOAP response generated by WPS has MultiRef nodes as a part of RPC encoded response. As we are not expected to change sender and receiver application, this being a migration project, we cannot ask sender application to change from RPC to Document style as this already impacts many interfaces. So we need to generate the same request/response as is generated by WPS via SAP PI. 

We feel we can handle the request part by importing the WSDLs as RPC style and/or doing some XSLT mapping but we currently are not clear on how to generate the RPC style response with MultiRef nodes. We basically need help if somebody has done some conversion from Document style to RPC style with MultiRef nodes earlier.

The WPS soap reponse looks some thing similar to this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

         <OutputResponse href="#id0"/>

      </p317:OutputResponseOperation>

       </multiRef>

     <multiRef id="id2" soapenc:root="0" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="m301:__Address" xmlns:m301="http://localhost/authentication">

     <address1 xsi:type="xsd:string">USA</address1>

     </multiRef>
