A few weeks ago, some accounts started receiving errors when viewing reports. These accounts could access reports without issue in the past. It only appears to affect some accounts, which is especially strange.
Error: The report can't be viewed because the underlying dataset uses row-level security (RLS).
Here is the report setup:
P1 Premium assigned to the origin workspace
Report built of multidimensional SSAS cube using a live connection
On-prem gateway is being used, and appears to be functioning without issue
Here's the kicker: there is NO row-level-security in this report, nor in the SSAS cube! RLS does not exist anywhere close to this report.
I am stumped, we've had a case open with Microsoft but no resolution yet. If we come to one, I will update this post.
