WSO2 ESB Preserve Payload Message

I have the below proxy service which is being called by a proxy service.

<?xml version="1.0" encoding="UTF-8"?>
<sequence name="seq_invchk_slpa_in" trace="disable" xmlns="http://ws.apache.org/ns/synapse">
  <log level="custom">
    <property name="STATUS::" value="***************************"/>
  </log>
  <payloadFactory media-type="xml">
    <format>
      <soapenv:Envelope xmlns:hnb="http://10.104.74.93/hnb"
        xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <soapenv:Header/>
        <soapenv:Body>
          <hnb:CheckInvoiceDetails soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
            <invoice_no xsi:type="xsd:string">$1</invoice_no>
          </hnb:CheckInvoiceDetails>
        </soapenv:Body>
      </soapenv:Envelope>
    </format>
    <args>
      <arg evaluator="xml" expression="$ctx:invoice_no"/>
    </args>
  </payloadFactory>
  <property name="ContentType" scope="axis2" type="STRING" value="text/xml"/>
  <header name="Action" scope="default" value="CheckInvoiceDetails"/>
  <property name="SOAPAction" scope="transport" type="STRING" value="CheckInvoiceDetails"/>
  <send>
    <endpoint key="gov:INVCHK/SLPA/endpoints/invchk_slpa_validation_ep.xml"/>
  </send>
</sequence>

When calling from a tool (SOAP UI) the service works without any problem.

But when calling from a system an issue arises. what I have traced out so far is during the correct call the payload factory message is sent as 

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:hnb="http://10.104.74.93/hnb" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soapenv:Body>
      <hnb:CheckInvoiceDetails soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
         <invoice_no xmlns="http://ws.apache.org/ns/synapse" xsi:type="xsd:string">17231374967185</invoice_no>
      </hnb:CheckInvoiceDetails>
   </soapenv:Body>
</soapenv:Envelope>

When the erroneous call is made the payload message goes out of the ESB as

<?xml version="1.0" encoding="UTF-8"?>
<hnb:CheckInvoiceDetails xmlns:hnb="http://10.104.74.93/hnb" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
   <invoice_no xmlns="http://ws.apache.org/ns/synapse" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xsd:string">17231374967185</invoice_no>
</hnb:CheckInvoiceDetails>

which I think causes the issue. The response i get from the client during the erroneous call is 

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap .org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode xsi:type="xsd:string">SOAP-ENV:Client</faultcode>
         <faultstring xsi:type="xsd:string">Operation '' is not defined in the WSDL for  this service</faultstring>
         <detail xsi:type="xsd:string" />
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

How can I preserve the SOAP message as it is and send it out when being called by a system.

Why are the soap namespaces getting mixed up in the method level <hnb:CheckInvoiceDetails xmlns:hnb="http://10.104.74.93/hnb" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

Any help will be very much appreciated.

You at least have to change content of Payload Factory mediator to 

<payloadFactory media-type="xml">
    <format>
          <hnb:CheckInvoiceDetails xmlns:hnb="http://10.104.74.93/hnb">
            <hnb:invoice_no xsi:type="xsd:string">$1</hnb:invoice_no>
          </hnb:CheckInvoiceDetails>
    </format>
    <args>
      <arg evaluator="xml" expression="$ctx:invoice_no"/>
    </args>
  </payloadFactory>

pay attention to invoice_no tag. Originally it is not clear what a namespace it suppose to have, it actually nest namespace of synapse engine, by default. So better to assign namespace explicitly.

Synapse engine will add envelope by default.

If a message type is unknown this returns soap12. found in documentation of Synapse. Property Content-Type without messageType is useless.
