I use RLS on two different DataSets that reside in two different Workspaces.
The goal is to use the Table from Dataset 1 in DataSet 2 with the RLS from DataSet 1.
This works perfectly fine, however it is not possible to impersonate an other user to test the RLS.
When I use show as different user and enter the email adress all visuals are broken. however when I do the same with this user in Power BI Desktop no RLS filtering takes place at all.
Nevertheless when I log in to Power Bi with the test user and look at the App, the RLS applies correct.
Therefore RLs works for the user in life but I can not test because the impersonation doesnt work.
Is this a Power BI bug?
Greetings
Sounds like a bug/incomplete feature of the composite model. You may want to raise this in the Issues section.
