In this deep-dive session, Ville Gullstrand takes Power BI users on a comprehensive journey through Row-Level Security (RLS) — from foundational understanding to advanced implementation strategies. He begins by reframing RLS not as a tool for security, but for maintainability, especially when handling datasets for multiple users with complex access needs. Through illustrative examples, Ville reveals how quickly things spiral out of control when relying on duplicated reports and static filters.
From basic RLS rules using "Manage Roles" to dynamic approaches involving DAX functions like USERPRINCIPALNAME and PATH, Ville builds layer by layer. You'll learn about using user access tables, filtering by hierarchy for managerial access, and implementing a powerful "one role to rule them all" strategy. Ville finishes strong with a bonus trick to prefilter report views per user without limiting access—saving time and enhancing personalization. Whether you're a beginner or advanced Power BI developer, this masterclass delivers practical insight, clever workarounds, and long-term maintainability.
