Datamart data source credentials error

Hi,

I've build a datamart using sharepoint folders and web API for excel files.
I can edit and save, all fine.

I created a report, download it, add DAX table and upload.

But, at some point I get Data source datamart is missing credentials.
So I go to the settings, expand Data source credentials and get ( in red ) Failed to load data sources. Please try again later.
Anyone any idea?

Thanx,

Maaike

Try moving this to dataflows which you'll use as your sources for the datamart.
