@Nourwag This looks like the error you get when row level security is implemented. Either this is in the report or on a live connection to an AS model/cube. Either way, you need permission to see it. Your UPN is typically your email address.

I am facing an issue around the same thing. In my case User already has access to the cube. But username() function not displaying the login user email address. Instead display the account used for connecting to Analysis service cube. I am using live connection for this.
