Power Fx function
Read and shape data
Distinct
Unique values only, duplicates removed.
What it does
Unique values only, duplicates removed.
The job: Take a table or data source, keep the rows you want, and reshape the columns for display.
How to use Distinct
Start from the task, not the alphabet. If you are shaping rows for a gallery, reach for Distinct alongside the other data functions in its group; if you are saving, navigating, or changing state, use it on an event such as a button OnSelect rather than in a display property. When a formula misbehaves, check for a blank value where you expected text, then confirm the behaviour against the examples in the Power Fx function reference hub.
