I have a problem that I've never seen before.
I have an Office 365 ProPlus license in my computer and my company has the Office 2013 Professional Plus with PowerPivot plugin installed on remote access service.
I developed a report by using Office 365 and when I try to use Office 2013 on remote service some formulas doesn't work.
Example: DATEDIFF and VAR
Is there different DAX version?
