setting soap message header

Dear Community,

I have to set some information in the header of a soap message. Does anybody know how this can be handled in Cloud Studio?

This is the information which should be added in the header:

<wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">

     <wsse:UsernameToken wsu:Id="UsernameToken-75" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

     <wsse:Username>xxxx</wsse:Username>

     <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">xxxx</wsse:Password>

</wsse:UsernameToken>

      </wsse:Security>

Kind Regards,

Lukas
