data refresh issue - unsupported data source
I've read the existing posts on this but are of no help... I have an excel file of 3..4MB as my data source, loaded into powerbi.com I created several reports and a dashboard off of it upon tryin...
Have exactly te same issue!
Pro user, DataSet is stored in excel file OneDrive for Business.
More over there also an issue with PowerPivot (Excel) it stucks and crashes for a secon day in a row...
I've noticed, if I remove some measure or calculated column from my datamodel in excel and manage to save the file (without PowerPivot got crashed) then I able to update my dataset in Power BI, but just once. For a secon try I get the same error "unsupported data source".
Maybe tha issue came with some recent automatic udpade for office 365 or something like that, because no such thing happened before. Working with this datamodel for a couple of weeks already.
