Create operation using OData.request()

Hi,

In my SAPUI5 application i am trying to create a record in backend SAP system via NW Gateway system. For this my client is using SMP3.0 SP05 as a middle-ware server through Relay server configured. First i tried using REST Client, & i am able to create it successfully after getting the X-CSRF-Token. But when i am using OData.request() method to create the entry, i am getting forbidden error(403). Please check my below code:-

onPressSubmit:function(){  var newUrl = "";  var token = "";  newUrl = sap.app.config.smpUrl +  sap.app.config.CreateActivity;  jQuery.sap.require("sap.ui.model.odata.ODataModel");  var f = {  headers : {  "X-Requested-With" : "XMLHttpRequest",  "Content-Type" : "application/atom+xml",  "DataServiceVersion" : "2.0",  "X-CSRF-Token" : "Fetch",  "X-SMP-APPCID": appCID,  },  requestUri : newUrl,  method : "GET"  };  var parameters={        "IvDescription":"Test by UI Team",        "IvStartDt":"2016-03-07T00:00:00",        "IvEndDt":"2016-03-07T00:00:00",        "IvStartTime":"100000",        "IvEndTime":"",        "IvStatus":"E0001",        "IvCategory":"IvActivityType",        "Text":"Test team UI",                       "address":[          { "PartnerName":"",          "PartnerFct":"00000009",          "PartnerId":"7000011183"          },          {          "PartnerName":"",          "PartnerFct":"ZSEESP1",          "PartnerId":"EM00700112"          },        ],                  };  OData.request(f, function(data, oSuccess) {  oToken = oSuccess.headers['x-csrf-token'];  token = oSuccess.headers['x-csrf-token'];   var cookie = oSuccess.headers['Set-Cookie'];  /* oHeaders = {  "x-csrf-token" : oToken,  };*/   OData.request({                   requestUri : newUrl+"/AppointmentCreateStdSet",                headers : {                 'X-Requested-With': 'X',     "Content-Type": "application/json",   'Accept' : 'application/json',    "DataServiceVersion" : "2.0",  "X-CSRF-Token" : token,  "X-SMP-APPCID": appCID,  "Access-Control-Allow-Origin": "*",             "Access-Control-Allow-Methods": "GET,PUT,POST,DELETE,OPTIONS",             "Access-Control-Allow-Headers": "Origin, Content-Type, Authorization, Accept, X-Request-With",             "Access-Control-Allow-Credentials": "true",             'Authorization' : 'Basic ' + btoa("username" + ':password'),             "Cookie":cookie                            },                   method : "POST",                                    data:parameters       },                   function(data,request) {                   alert("Employee Created Successfully");                           location.reload(true);       },          function(err) {                   alert("Employee Creation Failed");       });     });

In chrome i am getting following response 403 forbidden error as shown below.

I don't understand why i am getting "x-csrf-token:Required" as i can see token is successfully posted in the Request Header.

Please suggest if i am doing anything wrong here.

Thanks,

Shrikant.
