Change SOAP Header: Consuming Webservice

Hi All,

  How can I change soap header from consuming webservice? we are on SAP 7.00 SP15 (No XI or PI)

  I am able to call some methods that do not require the header for third party web service (.net).

  This is the header that sap generate:

<soap-env:Header>
 ....<n1:MessageID xmlns:n1="http://schemas.xmlsoap.org/ws/2004/08/addressing">uuid:4bdbf1ed-6c9c-1d52-e100-0000c0a8cf8a</n1:MessageID>  ....</soap-env:Header>

  This is the header that third party web service require.

  <soap:Header>    <MultiSpeakMsgHeader Version="string" UserID="string" Pwd="string">  </soap:Header>

Thanks,

Chaiphon
