I found a couple posts that grazed the subject but none that nailed my need. It sounds like user based data filtering, which is a *pretty fundamental* requirement, is pretty immature or void in Power BI. From what I've read, it appears that the USERNAME() function is only effectual when used against a cube, etc.
What I want and REALLY NEED... I need to assign the user name to a SQL function parameter which can not be altered by the user. How can I do that? I can take care of the rest within my SQL table valued functions.
Perhaps there are some other or better ways to ensure data filtering. I need something users can't play with that ensures the data presented to them is appropriate for them.
Thanks,
