Upload a file for a WTDocument from Thingworx

[SaranKarthick]

var params = {
    infoTableName : "InfoTable",
    dataShapeName : "demo.wt.doc.WTDocument"
};
// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(ptc-demoProblemReportShape)
var newDocument = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params);
newDocument.AddRow({
    name: "TestDocument1",
    number: "000001",
//    'state--state': "Released",
//    'versionInfo--identifier--versionId': "A",
    type: "wt.doc.WTDocument",
    containerReference: "OR:wt.inf.container.ExchangeContainer:5:219321006-1506495753013-268599241-1-56-168-192@blrmaigwd27067.itcinfotech.com",
    'folderingInfo--cabinet': "OR:wt.folder.Cabinet:280:219321006-1506495753013-268599241-1-56-168-192@blrmaigwd27067.itcinfotech.com"
});
var params = {
    dataShape: 'demo.wt.doc.WTDocument' /* DATASHAPENAME */,
    objects: newDocument /* INFOTABLE */
};
// result: INFOTABLE dataShape: "undefined"
var createdDocument = me.Create(params);

var result = createdDocument;

With this service i'm able to create the WT Document in windchill. But i can't succeed in attaching a file to this document. Should i add the file as one of the properties of the document?

Please provide a methodology for my requirement.

Thanks and Regards
