KEEPFILTERS DAX Function (Filter)

Changes the CALCULATE and CALCULATETABLE function filtering semantics.


KEEPFILTERS ( <Expression> )
Parameter Attributes Description

CALCULATE or CALCULATETABLE function expression or filter.

Return values

Even though KEEPFILTERS could be considered a table function, as a filter modifier it changes the behavior of a predicate or of the table expression provided as an argument. Therefore, it cannot be considered a function returning a value.


KEEPFILTERS is a filter modifier that does not remove an existing column or table filter in the filter context that conflicts with the filter applied by the argument of KEEPFILTERS used as:

  • a filter argument in CALCULATE / CALCULATETABLE
  • an argument of an iterator used in a following context transition

In the following example, KEEPFILTERS is used as a filter modifier in CALCULATE. The Always Red Sales measure returns always the sum of the Red products, overriding any existing filter over the Color column. The measure Only Red Sales return the sales of red products within the set of selected colors. If Red is not included in the current filter context, the result is blank.

Always Red Sales :=
    [Sales Amount],
    'Product'[Color] = "Red"

Only Red Sales :=
    [Sales Amount],
    KEEPFILTERS ( 'Product'[Color] = "Red" )

When KEEPFILTERS is used for an iterator, it keeps the existing filter context when there is a context transition. The measure Average Sales Only Trendy Colors computes the average Sales of the colors included within the Trendy Colors, without considering those that are not in the current filter context. If the measure is evaluated in a filter context that has a filter over Red, Yellow, and White, the result will average only Red and White, ignoring Yellow and Blue colors.

Average Sales Only Trendy Colors :=
VAR TrendyColors =
        { "Red", "Blue", "White" },
        KEEPFILTERS ( TrendyColors ),
        [Sales Amount]
-- Compare a White color filter with and without KEEPFILTERS
    MEASURE Sales[White Sales] = 
        CALCULATE ( 
            [Sales Amount], 
            Product[Color] = "White" 
    MEASURE Sales[White Sales Keep] = 
        CALCULATE ( 
            [Sales Amount], 
            KEEPFILTERS ( Product[Color] = "White" )
        VALUES ( 'Product'[Color] ),
        "Sales Amount", [Sales Amount],
        "White Sales", [White Sales],
        "White Sales Keep", [White Sales Keep]
