No-Access-Control Allow-Origin Header in SAPUI5

Dear All,

I am calling the Odata service from my UI5 application and getting the below error like

XMLHttpRequest cannot loadhttp://jdb.com:8024//sap/opu/odata/sap/ZMM_PO_GW_SRV/?sap-client=110" No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://jdb.com:8024 is therefore not allowed access. The response had HTTP status code 401.

But i tried by using the disable of security in Chrome browser. Still getting the same server.

But in the console URL is fetching the data from the Backend  . Could you please  help for the above problem.

var oModel = new sap.ui.model.odata.ODataModel(url,true);

sap.ui.getCore().setModel(oModel);

oModel.read('/VendorValidSet', null, ["($filter=PoNumber eq'"+input+"')?sap-client=110"], false, function(oResponse)

{

procType = oResponse.results[0].MessageText;

}

Due to above error i am OModel.read is failing and hence not able to load the data from the Backed to the frontend.

Thanks for your help.
