ISAFTER DAX Function (Information)

Returns true if the list of Value1 parameters compares strictly after the list of Value2 parameters.

Syntax

ISAFTER ( <Value1>, <Value2> [, [<Order>] [, <Value1>, <Value2> [, [<Order>] [, … ] ] ] ] )
Parameter Attributes Description
Value1 Repeatable

Expression to be compared with second parameter.

Value2 Repeatable

Expression to be compared with first parameter.

Order Optional
Repeatable

The order to be applied. 0/FALSE/DESC – descending; 1/TRUE/ASC – ascending.

Return values

Scalar A single boolean value.

Returns TRUE when the set of values passed as arguments in Value1 is “greater than” the set of values passed as arguments in Value2.

Remarks

Usually this function is evaluated in a filter condition during an iteration, applying it to the current row context. However, ISAFTER uses the existing evaluation context, so any row context must be created outside of ISAFTER, which is not an iterator.

A blank value is matched with BLANK(), in this comparison a blank and an empty string are considered as different values and an empty string is after a blank in ascending order.

Examples

The following query filters the months greater than October 2008 by using the ISAFTER function in the filter condition of FILTER.

EVALUATE
FILTER (
    SUMMARIZE (
        'Date',
        'Date'[Calendar Year],
        'Date'[Month],
        'Date'[Month Number]
    ),
    ISAFTER (
        'Date'[Calendar Year], "CY 2008", ASC,
        'Date'[Month Number], 10, ASC
    )
)
ORDER BY
    'Date'[Calendar Year],
    'Date'[Month Number]
