Hi,

I'm using Power BI server to develop a dashboard. The data source is a SSAS cube.

Yesterday, when I tried to click on "see records" I've received the follwoing message:

"Couldn't load the data for this visual

We can't display the detailed record table for this data source without a unique key. Create a flat table with all fields to see a breakdown of the measure with identical rows aggregated.
Please try again later or contact support. If you contact support, please provide these details.
