RANK.EQ – determine the order of value in some column (DAX – Power Pivot, Power BI)

This article describe the RANK.EQ function, that can be used in Power Query to show the rank of some value in DAX (DAX is a language for Power Pivot and Power BI).

Let´s use this table with names of students and their scores from test. We can be interested in the order position of the values in “Test score” column.

Let´s add a new column and type:

• Order from highest value = RANK.EQ(Students[Test score];Students[Test score];DESC)

Order from highest value – header of new column

• RANK.EQ- function name
• Students[Test score] – value, whose order is being evaluated
• Students[Test score] – area, in which the value is being evaluated
• DESC – direction of sorting (DESC or ASC)
