Filter Expression Role Level Security

[freak]

Hello

I have a table like this

Company	principalName	Data
company1	user1	..
company1	user2	..
company2	user3	..
company2	user4	..

Wenn a User (user1 and 2) from Company1 open the report he should see all data from company1. 

User (user3 and 4) from company2 will only see Data from company2

principalName is USERPRINCIPALNAME()

How can i write a Filter Dax Expression?

Thanks

Hi @freak ,

It sounds like you need an RLS setup with hierarchy.
You could try using Dynamic Row Level Security with Manager Level Access in Power BI.

The very first step is always identifying who is the person logged into the report in Power BI Service. This can be done with Username() or UserPrincipalName() functions in DAX.

We can use a DAX expression to identify is the person logged in, a manager or not. This can be done with a simple MAXX expression.

For more information，you can refer to：Dynamic Row Level Security with Manager Level Access in Power BI 

Hope it helps,

Yes this works, but i want more 🙂

When i use [principalName] = USERPRINCIPALNAME(), user1 see only data from user1. user1 should see data from company1, as well from user2 but not from user3 and 4

@freak , In role you can add filter

[principalName] = USERPRINCIPALNAME()

Is this expression not working ?
