In this video, you’ll master the ALL function in Power BI DAX and understand how it removes filter context to return true totals. This is one of the most important DAX functions used in % of Total calculations, contribution analysis, and performance comparisons.
We’ll walk through a real Calculate + ALL assignment, where you’ll create measures like All Returns and % of All Returns using CALCULATE and ALL together. You’ll learn how to ignore filters, control evaluation context, and build professional-level business calculations used in real dashboards.
