Dynamic Row-level Security 🔐 - Based on Dimension Tables

[@BILingualAnalytics]

Thanks for all the questions about how to expand this Dynamic RLS setup to have multiple groups available per user. First of all, you need to add a row to each security setup per user and then adjust the _RLS variable to this: var _RLS = SWITCH( TRUE(), OR( "All" IN _Rest, [Group] IN _Rest ), TRUE(), FALSE() )

[@MichaelHernandez-tl7jy]

But when do you do "ALL" IN _Rest what do you mean with ALL

[@BILingualAnalytics]

@@MichaelHernandez-tl7jy that's what I have in my users table "All" or "Electronics" or "APAC"

[@MoonShine-bs6cl]

It's based on email ids per user and i have created a seperate table which is region wise and into many to many relationship by using dax userprincipalname ()

This is great! Didn’t think it would work, but I got it to work finally. Unfortunately now I realized I need to base my RLS on two columns within the same dimension table instead of 2 different table. How do you accomplish this?

[@BILingualAnalytics]

When it comes to setting up the RLS instead of jumping over to another table just select a different field in the same table. it will add a "&&" line so apart from that everything should work fine :) Hope this helps!

Hello, thanks for the video. It explained very well the dynamic RLS. But I have an issue. What is I need an "OR" condition instead of "AND". For instance, a person X has access to all "APAC" region (no matter what the product is) and to the product "Electronis" no matter the region is. It is a bit of complex to do (I assume) but it is needed in some business, for a person responsible of a region and of a product type (or a business unit). Could you please help ?

I would use an OR statement, something like this: var _RLS = SWITCH( TRUE(), OR( "All" IN _Rest, [Group] IN _Rest ), TRUE(), FALSE() )

[@manasippalapalli7934]

How can i use RLS to mask the data in a column? Or return the column with blank values?

[@BILingualAnalytics]

RLS and DataMasking are two distinct things. If you want to make sure that users can only see data they are allowed to see use RLS. If you want to mask data (ie make it visible but aggregate or non-identifiable) then you have to use a different approach.

Hi, I am using dynamic RLS but, I have one condition; If some user have more than 1 region, but at the login time (when user open BI report) can we give option for region which belongs to that particular user? So that, he choose that region & report shows that region data.

[@BILingualAnalytics]

Great question! If I understand the details correctly, I would solve that with a button/slicer combo. For those who have access to 1 region, just a single click to "enter" the report. For those who have multiple regions, select the relevant one. Now, I'm not sure how difficult it is to set up, but in theory would be possible.

[@pratikshavaishnav9635]

Hi, I have another question about Dynamic RLS. Do we have to add users under the role permission when publishing the report to power bi online?

Very good explanation, thank you. I am working on a challenge similar, more elaborate in two ways. A - the user should see all products in home organisation (via organisation dimension) and all products of products of specific product line over all sales organization. The code in your comment of two weeks ago suggests an solution by expanding the code in the video with OR. Correct? Question, would it also work by adding a second role? So one role for the home organisation with all products and one role of the product line with all organizations? B - the user might have to see multiple product lines and or organisations. Would the solution be to use IN in the switch formula; with multiple lines in the user table (via m) ?

[@BILingualAnalytics]

Thanks for the kind words! Well, let me try to answer your questions - hoping that I understand the desired outcome. Re A- if I understand correctly the security in scenario A is twofold. Let me try to use the video as an example. You need to limit access by "Channel" and by "Products" tables. By default, users should only see the channel they are working in. BUT they can also see the Products they are responsible for ALL channels. Is that right? While RLS is additive, meaning that if you are in multiple profiles you will see ALL of the profiles, in the given scenario you also need to find a way to add an additional group to the "Channel" table security profiles to allow not only 1st level of responsibility but also those channels where a set of products were sold. That's an interesting setup, so if you can confirm that my understanding is correct I'd need to work on it a bit. I'm planning on recording another video to answer the amazing questions that are asked here. I probably add this one as well. Re B - correct. That was an easier one than A :)

Im new to Power bi , how did you use equal sign to compare Group to CalculatedTable expression in the switch statement . how does this work? you are comparing single value to table

[@QuantumDot2]

I believe the calculated table is returning a single cell that corresponds to the USERPRINCIPALNAME() row & RLS category column in the Excel security table. Even though it’s still a table, I think that DAX is able to convert the single-cell table to a value when it makes the comparison in the SWITCH statement. Very clever trick, isn’t it! I suspect that if the Excel RLS table contained two rows for the same user but multiple RLS restrictions for a given category, it would fail the table value comparison in the SWITCH statement.

[@rushabhpatil96]

This is really a great video on dynamic RLS. 🫶🏽 I used this logic and it’s work great except at one scenario which is quite common to take place. Considering your same data set let say: User A has a RLS for All the products in APAC and Only Electronics in EMEA. Now if I give this data as a input in 2 row of excel RLS table, the output would show All product from APAC and EMEA since there is a “All” in the OR/IN statement from APAC which will overwrite the “Electronics” filter from EMEA. Is there any way we can fix this?

[@BILingualAnalytics]

Thanks! You are right, it is a more complex setup, but it could still be managed with dynamic RLS. a) For examples like this you can create a "special" list and use an AND statement. Let's say Geo AND Product should match rather than just Geo or Product. b) If the whole business is set up like that create the whole user table with that in mind. Hope this helps
