Hi,

Recently we update the SharePoint 2013 farm with SP1 and now when we do Manage Power pivot data refresh we get following error in ULS log. I search msdn and some people found IIS reset as resolution but in my case IISreset still does not resolve the issue. Is something that I am missing or can try to resolve this issue?
