Returns the highest value that results from evaluating an expression for each row of a table.

Syntax

MAXX(<table>,<expression>,[<variant>])

Parameters

Term	Definition
table	The table containing the rows for which the expression will be evaluated.
expression	The expression to be evaluated for each row of the table.
variant	(Optional) If TRUE, and if there are variant or mixed value types, the highest value based on ORDER BY DESC is returned.

Return value

The highest value.

Remarks

The table argument to the MAXX function can be a table name or an expression that evaluates to a table. The second argument indicates the expression to be evaluated for each row of the table.
Of the values to evaluate, only the following are counted:
- Numbers
- Texts
- Dates
Blank values are skipped. TRUE/FALSE values are not supported.
If the expression has variant or mixed value types such as text and number, then by default MAXX considers only numbers. If <variant> = TRUE, the maximum value is returned.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

Example 1

The following formula uses an expression as the second argument to calculate the total amount of taxes and shipping for each order in the InternetSales table. The expected result is 375.7184.

= MAXX(InternetSales, InternetSales[TaxAmt]+ InternetSales[Freight])

Example 2

The following formula first filters the InternetSales table by using a FILTER expression to return a subset of orders for a specific sales region defined as, [SalesTerritory] = 5. The MAXX function then evaluates the expression used as the second argument for each row of the filtered table and returns the highest amount for taxes and shipping for just those orders. The expected result is 250.3724.

= MAXX(FILTER(InternetSales,[SalesTerritoryCode]="5"), InternetSales[TaxAmt]+ InternetSales[Freight])
