around this issue You need to append a trailing backslash to the OData endpoint URLs when setting-up the data source/feed in PowerPivot, e.g.
code :
http://localhost:50885/Service.svc/

To fix this issue Solved this issue by changing data type to json instead of jsonp.The reason was jsonp was not allowing my web client to add Authorization header to my request.I found this fact from some forum in stack overflow.

it should still fix some issue I am trying to POST data from my API but I can't pass the basic authentication. , You can include the user and password as part of the URL:
code :
http://user:passwd@www.server.com/index.html

To fix this issue Solution
In order to achieve something similar to what is mentioned in the article (ie)
code :
static void ReadingODataEndPointByPassingMyBasicAuthCreds() {
  // e.g. URL =  http://localhost/myApi/odata
  var url = ConfigurationManager.AppSettings["MyAPIBaseUrl"]; 

  var container = new MyApi.Container(new Uri(url));

  container.SendingRequest2 += SendBaseAuthCredsOnTheRequest;

  foreach(var myEntity in container.MyEntities) {
   Console.WriteLine(myEntity.Name);
   Console.Write(string.Format("Description: {0}", myEntity.Description));
  }

  Console.Read();
 }

 private static void SendBaseAuthCredsOnTheRequest(object sender,
  System.Data.Services.Client.SendingRequest2EventArgs e) {
  var authHeaderValue = Convert.ToBase64String(Encoding.ASCII.GetBytes(String.Format("{0}:{1}", ConfigurationManager.AppSettings["username"]
                        , ConfigurationManager.AppSettings["password"])));
  //this is where you pass the creds.
  e.RequestMessage.SetHeader("Authorization", "Basic " + authHeaderValue); 

 }

will be helpful for those in need This is not an issue with Angular but with your backend. Angular is trying to make a preflight request by checking if the server returns OK on a OPTIONS request. You should set-up your backend to respond with 200 or 204 for OPTIONS requests.
If you are using node.js:
code :
app.use('/api', (req, res, next) => {
    /** Browser check for pre-flight request to determine whether the server is webdav compatible */
    if ('OPTIONS' == req.method) {
        res.sendStatus(204);
    }
    else next();
});
App::before(function($request)
{
    // Sent by the browser since request come in as cross-site AJAX
    // The cross-site headers are sent via .htaccess
    if ($request->getMethod() == "OPTIONS")
        return new SuccessResponse();
});
public function initialize() {
    parent::initialize();

    if($this->request->is('options')) {
        $this->response->statusCode(204);
        $this->response->send();
        die();
    }

    $this->Auth->allow(['add', 'token']);
}
