Power BI lets measure descriptions live beside DAX code
Reviewed by Helen Jones
Microsoft's July 2026 Power BI update adds inline measure descriptions in DAX Query View. A report builder can place a triple-slash comment above a Data Analysis Expressions (DAX) measure, and Power BI saves that text as the measure description for tooltips and quick queries.
Measure definitions often outlive the person who created them, while their business meaning sits in a separate document or is never recorded. That leaves inherited reports full of calculations whose names look familiar but whose assumptions are unclear. Keeping the explanation beside the DAX reduces the gap between the calculation and the meaning people attach to it. It will not make a weak measure correct, but it gives reviewers and future maintainers a better place to spot denominators, exclusions and business rules.
Analysis
Choose five measures that drive important decisions and add a plain-English description covering the calculation, denominator and material exclusions. Ask a colleague to interpret each measure from the description before you treat the documentation as finished.
