DAX Bottom N Measure

Flags whether the current item is among the lowest N performers by sales.

Ranking and Top NAdvancedbottom ntopnranking

DAX code

Bottom N Sales =
VAR N = 5
VAR BottomItems = TOPN(N, ALLSELECTED('Product'[ProductName]), [Total Sales], ASC)
RETURN
    IF(NOT ISEMPTY(INTERSECT(VALUES('Product'[ProductName]), SELECTCOLUMNS(BottomItems, "@P", 'Product'[ProductName]))), [Total Sales])

Notes

TOPN's ASC order flag reverses the sort, so this reuses the same pattern as a standard Top N measure.
