Javascript AGS inquiry call?

Example below calls PA02 and gets the value of Annual Hours and Pay Frequencey based on position.

var s = portalWnd.AGSPath;
s += "?_PDL=";
s += portalWnd.oUserProfile.getAttribute("productline");

s += "&_TKN=PA02.1&_EVT=ADD&_LFN=ALL&_RTN=DATA&_TDS=IGNORE&FC=N";
s += "&POS-COMPANY=" + vCompany;
s += "&POS-POSITION=" + vPosition;
// s += "&POS-EFFECT-DATE=00000000";
s += "&POS-EFFECT-DATE=" + vEffDate;

s += "&_OUT=XML&_EOT=TRUE";

var sAGSInfo = portalWnd.httpRequest(s);
if (!sAGSInfo || sAGSInfo.status)
{
vError = "Y";
return false;
}


var sFldNbr = sAGSInfo.selectSingleNode("//FldNbr").text;
var sMsgNbr = sAGSInfo.selectSingleNode("//MsgNbr").text;
var sMessage = sAGSInfo.selectSingleNode("//Message").text;

if (sMsgNbr == 0)
{
// alert("PA02.1 " + sMessage + " " + sFldNbr);
}
else
{
alert("PA02.1 failed for position:" + vPosition + " " + sMessage + " " + sFldNbr);
vError = "Y";
return false;
}

vAnnualHours = sAGSInfo.selectSingleNode("//POS-ANNUAL-HOURS").text;
vPayFrequency = sAGSInfo.selectSingleNode("//POS-PAY-FREQUENCY").text;

Super thank you ragu, I will give it a go.

Ragu..
What is the additional script source required for this in the html/javascript?

I have received the message, that 'portalWnd is undefined'.

I have common.js, commonHTTP.js, data.js and transaction.js in the header but portalWnd is not in there I don't think?

Sorry Roger. This is from within Design Studio. Not sure how it is done outside D/S.
