Frequently asked questions
Does the DAX generator know my model?
No. It works from your description, so mention table and column names and it will use them. Nothing is read from your Power BI tenant on this page.
Measure or calculated column?
Say which you want. If you do not, a measure is returned when the calculation aggregates and a calculated column when it is row-level.
Can it explain existing DAX?
Yes. Paste the DAX and ask for an explanation or a simpler version.
