How to Create and Use Flags as Measures with DAX in Power BI

Flags (e.g. “Is Current Year”, “Has Sales”) are useful as measures when you need dynamic 0/1 or true/false that respect filter context. They keep logic in one place and make report logic easier to read.

Patterns

Write a measure that returns 1 or 0 (or TRUE/FALSE) based on conditions (e.g. SELECTEDVALUE for a year comparison, or NOT ISEMPTY for “has sales”). Use these measures in other measures (e.g. conditional sums) or in visuals (e.g. background color, conditional formatting).

Avoid storing flags only in calculated columns when the flag depends on slicers or other context; measures adapt to the current filters.
