ISFILTERED DAX Function (Information)

Returns true when there are direct filters on the specified column.

Syntax

ISFILTERED ( <TableNameOrColumnName> )
Parameter Attributes Description
TableNameOrColumnName

The table or column to check the filter info.

Return values

Scalar A single boolean value.

TRUE when ColumnName is being filtered directly, or when any column of TableName is being filtered directly.

Remarks

A column is said to be filtered directly when the filter or filters apply over the column.
A column or table is said to be cross-filtered when a filter is applied to any column of the same table or in a related table.

ISFILTERED can check whether a column is being filtered directly or if any of the columns of the table is being filtered directly.

ISFILTERED supports a table argument since SSAS 2019 or Power BI April 2019. Former versions only support the column name argument.

Examples

--  ISFILTERED checks whether a column has a direct filter
--  ISCROSSFILTERED checks whether a column has either a direct
--  or an indirect filter (which is a filter propagated from a related column)
--
--  In this example we place the filter on the 1 side of a 1:* relationship
