Set Username and password

Dear All,

We are stuck in one of the scenario where we need to add Username and Password in SOAP request itself through code as below,

<soapenv:Header>

      <urn:AuthenticationInfo>

         <urn:userName>ABC</urn:userName>

         <urn:password>XYZ</urn:password>

         <!--Optional:-->

         <urn:authentication>?</urn:authentication>

         <!--Optional:-->

         <urn:locale>?</urn:locale>

         <!--Optional:-->

         <urn:timeZone>?</urn:timeZone>

      </urn:AuthenticationInfo>

   </soapenv:Header>

Now what changes we need to do to in Sender Agreement / SAP PI to make such authentication work ?

Regards,

Alex
