This is Episode 18 of the free Namaste Power BI course on DevWithData — covering filter context control. Watch the video above, then pass the MCQ checkpoint to unlock the next episode and update your Data Readiness Index score.

Key Takeaways

→ALLSELECTED respects report/page filters but removes visual filters
→SELECTEDVALUE returns the current slicer value (or alternate if multiple)
→HASONEVALUE checks if exactly one value is in filter context
→ISINSCOPE determines if a column is used in a visual's grouping

⚠ Common Interview Pitfalls

•Confusing ALL (removes everything) with ALLSELECTED (respects outer filters)
•Using IF(HASONEVALUE...) when SELECTEDVALUE handles it cleaner
•Not understanding that grand total row has different filter context
