Howdy. I've just started playing around with PowerPivot, and wondered if it was a vehicle for delivering secure interactive reports to external clients via SharePoint Online. So I signed up for a test sharepoint online account, whipped up my first PowerPivot dashboard with some sliders in it (using some .txt files as data sources) and uploaded it to my test SharePoint Online site.
But of course, when I try to use the sliders, the pivot tries to refresh, and then I get an error message "the data connection uses windows authentication and user credentials could not be delegated."
So I'm wondering whether powerpivot via sharepoint allows you to link in to external data sources, or whether all the data be within the powerpivot file itself as linked tables.
Anyone played around with Sharepoint and PowerPivot together yet?
