Hi, Anonymous 

According to your description, do you mean that you added one username to more than roles in the RLS?

 

In this case, RLS filters become additive. It means report users can see table rows that represent the union of those filters. You can refer to this link:

Maybe switching to the Dynamic Row Level Security with Organizational Hierarchy can be a choice for you:

Thank you very much!

Hi v-robertq-msft , this is my case but I don't have hierarchy, more of two independent username sets to be used in RLS which intersect. When one username is added to more than one report security groups RLS stops to work and all is visible for the user.
