Upload “Power BI Files” only to “Power BI Library” in SharePoint site

If you want to restrict to only upload Powe BI file (.pbix file) to “Power BI Library” as below screenshot, you can use following JQuery code in HTML masterpage.

//Check upload file extension is PowerBI files - only for Power BI Library
CheckAssetLibMediaExtension = function(){

if (window.parent.location.pathname.toLowerCase().indexOf('powerbifiles')>0)
{
      var allowedExtensions = /pbix/;

      var inputFile = $("input[name$='InputFile']").val();

      var ext = inputFile.substr(inputFile.lastIndexOf('.') + 1);

     console.log(ext);

      //var
     $currentIFrame = $('.ms-dlgFrame');

    if (!allowedExtensions.test(ext)) {
          $("input[name$='btnOK']").attr('disabled','disabled');

           alert('Only Power BI file with file extension name is .pbix can be uploaded                  to this library.');

 $currentIFrame.contents().find("body .ms-error").css('display','block !important');

//$currentIFrame.contents().find("body .ms-error>span").text("Only Power BI file (file extension is '.pbix') can be uploaded to this library.");

  } else
  {
         $("input[name$='btnOK']").removeAttr('disabled');
   }
}
}

SharePoint 2013 error - "Application error when access /_vti_bin/client.svc"

I had been received a error message " Application error when access /_vti_bin/client.svc, Error=Path '/_vti_bin/client.svc/ProcessQuery' is forbidden " when try to add user account to a user group in SharePoint 2013 Portal . I searched the issue in google and found out it may related to security issue in local folder  "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI" of " /_vti_bin/client.svc ". I verified the user permission on this folder and found out that "IUSR" for IIS is not there, and so I granted user account "IUSR" read and execute permission in this folder.

Enable the Microsoft Power BI report file type (.pbix) in SharePoint Search

Image
By default, the Microsoft Power BI report file (.pbix) is not in the list of file type in SharePoint 2013 search configuration in Central Admin, and so you wouldn't open the Power BI file directly by clicking the link from the search result page. However, it's easy to add this file type by following configuration. Open “Central Admin” site, and then go to "Manage service applications”->”Search Service Application XX” (use the actual name of the “Search Service Application” in your site). Click on the “File Type” in left side navigation. Click the New File Type button and type PBIX (no period needed) in the File extension box and click OK. Restart the Search Service: Go to local “services”, stop the SharePoint Server Search service and start it again. Reset Your Index: Back on the Search Administration page within Central Administration you will want to click on the Index Reset link under Crawling on the left side menu. Press the Reset Now button.
