In Tableau, what is the key difference between a Top N filter using a Quick Filter versus a Top N filter using an INDEX() table calculation?

Accepted Answer

The key difference lies in when the filter is applied. A Top N Quick Filter limits records at the query level, whereas an INDEX() table calculation filter applies after aggregations. This distinction makes the INDEX() approach useful for dynamic rankings. The correct answer highlights this difference.
