SOAP WS-Security

Hi All,

I am doing a Proxy(SOAP) to SOAP synchronous scenario. I am on 7.4 single stack. When the data is trigerred from ECC I need to build a WS-Security header and send it across to the third party.

I have done a XSLT mapping to add the below header in the message. My Question is how or from where can I get the username and password values to be entered . I mean how do we populate the values in that field. Currently I am using test which is hard coded.

  <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"

      soapenv:mustUnderstand="1">

      <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"

        wsu:Id="UsernameToken-21280292">

        <wsse:Username>test</wsse:Username>

        <wsse:Password>test</wsse:Password>

    </wsse:Security>
