Hi
We have on-prem Report Server connected to SSAS Tabular Model (Connect Live)
We have used custom authentication (using GitHub)
For implementing RLS , we need to capture the login id of the user logged in , hence we used customdata function
I remember it was working earlier , but now it is not working..
eg: Create a measure ConnectedUser=CUSTOMDATA() -- gives the userid who have logged into powerbi
Now it is giving blank
Pls suggest
