How does RLS interact with relationships?

< 1 min read

RLS filters propagate through relationships based on filter direction.
When a role applies a filter on a dimension table, it flows to the related fact table.
For example, filtering Region dimension automatically restricts Sales fact data.
In one project, we applied RLS on a security table linked to Region.
Because of the active relationship, only relevant sales records were visible.
If relationships are inactive or incorrectly configured, RLS will not work properly.
Bidirectional relationships can also expand filter propagation unexpectedly.
So correct relationship design is critical for secure and accurate RLS behavior.
