SOAP receiver - wsdl errors

Hi

We have a synchronous Proxy to SOAP scenario. I'm using the wsdl sent by our vendor. It seems to be working when I use SOPAUI. But when I send a message from PI, it fails in the vendor's system.

When I import the wsdl into SOAPUI, the wsdl looking like this-

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

   <soapenv:Header/>

   <soapenv:Body>

     <def:updateStyleNumber soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

         <in0 xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">

         &#38;lt;Product name=&#38;quot;FOSMBAG203&#38;quot; revision=&#38;quot;Fall 2013&#38;quot; type=&#38;quot;Bag&#38;quot; StyleNumber=&#38;quot;ABC12345&#38;quot;/&#38;gt;

         </in0>

      </def:updateStyleNumber>

   </soapenv:Body>

</soapenv:Envelope>

But when you look at the soap message from PI, it has the operation missing.

<SOAP:Envelope

        xmlns:SOAP='http://schemas.xmlsoap.org/soap/envelope/'>

        <SOAP:Header/>

        <SOAP:Body>

            <ns0:in0

                xmlns:ns0='http://DefaultNamespace'>

                &#38;lt;Product name=&#38;quot;FOSMBAG203&#38;quot; revision=&#38;quot;Fall 2013&#38;quot; type=&#38;quot;Bag&#38;quot; StyleNumber=&#38;quot;ABC12345&#38;quot;/&#38;gt;

                </ns0:in0>

            </SOAP:Body>

        </SOAP:Envelope>

I have highlighted the missing line in blue. I'm not sure how to resolve this. Any suggestions would be greatly appreciated.

Thanks
