Row level security help

[DiKi-I]

Can I use username() for row level security instead of userprincipalname(). I have ad user name in the table but not user email. Could you please let me know if this will work. Also my table is in direct query mode so I won't be able to modify the data.

Hi @DiKi-I 

In addition to @Idrissshatila @Cookistador below additional suggestions for implementing Row-Level Security (RLS) in Power BI.

• Dynamic RLS using USERNAME() or USERPRINCIPALNAME(): Store user-to-data mappings in a table and filter based on the logged-in user dynamically.
• Using security groups: Assign roles via Azure AD security groups and filter data based on group membership.
• Testing RLS using "View as Role": Always validate roles in Power BI Desktop before publishing.
• Combining static and dynamic RLS: Use hybrid logic for more complex access control scenarios.

If the above information is helpful, please give us Kudos and mark the response as Accepted as solution.

Hello @DiKi-I ,

make sure to test it in the view role before applying it, since this is a sensitive case.

my username is getting resolved to upn in service. I will test with the actual data once I have gateway setup.

yes this approach also works

just to be sure that the name your have in the table is in the right format

Create a measure _Test = Username()

Then add this measure in a card, to see how it is formatted vs what you have in the table (maybe you will have to add the domain in the list)
