Reading custom SOAP header with XHeaderName1

Question

Hello Experts,
I have a SOAP to File scenario and I am trying to do dynamic receiver determination by looking at the SOAP request header info. I am adding a custom field (System_ID) that I want rules to run against in Receiver Determination..
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:urn="urn:*******************">
<soapenv:Header>
<System_ID>100</System_ID>
</soapenv:Header>
  <soapenv:Body>
   </soapenv:Body>
</soapenv:Envelope>
In the Receiver Determination I have multiple rules using SOAP context object to  XHeaderName1 = the System_ID (100) to pass the message to the right system at runtime according to the  System_ID.
In the SOAP sender channel I have Set Adapter-Specific Message Attributes and Variable Transport Binding checked. I also have the variable name System_ID in the first Variable Header (XHeaderName1).
In the SOAP sender Conversion Parameters I have Do Not Use SOAP Envelope and Keep Headers checked, as well as nosoap=true in the SOAP request URL.
I'm getting the System ID to show in XI in sxmb_moni in the Header but no where do I see it being used with XHeaderName1.
Am I using XHeaderName1 right? If not could you advise as to how XHeaderName1 should be used?
My requirement is to read system ID from Header, not payload.
Thank you!

I was able to find a solution to my problem.
I created a basic senario below to test:
1.A basic Asynchronous scenario is created using a SOAP sender adapter to 2 possible flat file receivers.
2.The SOAP sender channel will have the option u201CDo Not Use SOAP envelopeu201D checked and SOAPUI URL will have u201C&nosoap=trueu201D added to the end.
3.The receiver system name will be stored in the WS-Addressing u201CActionu201D field sent from SOAPUI.
4.Two ABAP mappings are created. One mapping will extract the system number from the WS-Addressing u201CActionu201D field. The other mapping will extract just the body of the SOAP message to send along. Using regex and string manipulation in the ABAP mappings we can reuse the mappings for any SOAP message.
5.Enhanced (Extended) Receiver Determination is selected and interface mapping using system/XI ReceiverDetermination  service interface is used to capture the receiver system.
While this is a solution is not the best, it is a solution. Upon research I found a recent SAP Note 1385579 talking about implementing a SAP delivered generic SOAP Sender AXIS handler com.sap.aii.axis.soap.HeaderExtractionHandler to extract SOAP Header elements and place in message attributes. I will be trying this out.
