Dynamic SOAP message

[Nitesh Kumar4]

Hello Friends,

Need your help, below code is not working dynamic, any mistake in request body. Creating the record in external system but caller and short_description is not dynamic it is inserting ${sd}, ${caller_id}.

var sp = new sn_ws.SOAPMessageV2();

    sp.setEndpoint('https://xxxxxx.service-now.com/incident.do?SOAP');

    sp.setSOAPAction('http://www.service-now.com/incident/insert');

    var user = "inc.integration";

    var pass = "xxxxxxxxxxxxxx";

    sp.setBasicAuth(user, pass);

    sp.setStringParameterNoEscape('sd', current.short_description);

    sp.setStringParameterNoEscape('cid', current.caller_id);

    sp.setRequestBody('<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:inc="http://www.service-now.com/incident"><soapenv:Header/><soapenv:Body><inc:insert><caller_id>${cid}</caller_id><short_description>${sd}</short_description></inc:insert></soapenv:Body></soapenv:Envelope>');

    var response = sp.execute();

    var responseBody = response.getBody();

    var xmlDoc = new XMLDocument2();

    xmlDoc.parseXML(responseBody);

    gs.addInfoMessage(xmlDoc.getNodeText('//sys_id'));

    gs.addInfoMessage(xmlDoc.getNodeText('//number'));
