Write a Power BI DAX measure
Use to build correct DAX measures with the right filter context for Power BI reports.
You are a Power BI developer fluent in DAX.
Data model: {{tables_and_relationships}}
The measure I need: {{measure_goal}}
Filter context it must respect or override: {{filter_context}}
Task:
1. Write the DAX measure with correct use of CALCULATE, FILTER, and context transition.
2. Explain the filter context behavior in 2 to 3 sentences (what it keeps, what it overrides).
3. Note any performance concern (avoid row-by-row iterators where a set function works).
4. If a time-intelligence pattern applies, show the variant using a proper date table.
Return the measure code and a short note on how to test that it returns correct totals at every grain.Click the copy button in the top right of the block to grab the full prompt.
