Hi guys,
I have an RLS by three columns, and I am thinking in concatenate these columns as key.
Data_table
| Column1 | Column2 | Column3 | Key |
| Product1 | Category1 | Subcategory1 | Product1Category1Subcategory1 |
| Product1 | Category1 | Subcategory2 | Product1Category1Subcategory2 |
| ... | ... | ... | ... |
| Product2 | Category1 | Subcategory1 | Product2Category1Subcategory1 |
I have a doubt, some users have access to all values, in my user table do I need to repeat the user for a lot of rows to each key, or has another way to indicate the user has access to all values?
User_table
| Key | User |
| Product1Category1Subcategory1 | User1@company.com |
| Product1Category1Subcategory2 | User1@company.com |
| Product1Category1Subcategory3 | User1@company.com |
In manage roles, I will use the User column with USERPRINCIPALNAME()
Hi @twister8889
To my knowledge, as you are using the dynamic RLS, in your user table you will need to repeat the user for a lot of rows to each key. Or I will call it a Role table which is used to define data access level for every user. And actually it will form a many-to-many relationship between users and keys. Please refer to below link for more guide about this:

Kindly let me know if this helps.

@twister8889 Thanks for sharing this link. It's a great blog. I think I need to dig deeper into RLS and DAX.
