Returns the last date in the current context for the specified column of dates.
Syntax
LASTDATE(<dates>)
Parameters
Term |
Definition |
|---|---|
dates |
A column that contains dates. |
Return Value
A table containing a single column and single row with a date value.
Remarks
Note
To understand more about how context affects the results of formulas, see Context in DAX Formulas.
The dates argument can be any of the following:
A reference to a date/time column,
A table expression that returns a single column of date/time values,
A Boolean expression that defines a single-column table of date/time values.
Note
Constraints on Boolean expressions are described in the topic, CALCULATE Function.
When the current context is a single date, the date returned by the FIRSTDATE and LASTDATE functions will be equal.
Technically, the return value is a table that contains a single column and single value. Therefore, this function can be used as an argument to any function that requires a table in its arguments. Also, the returned value can be used whenever a date value is required.
This DAX function is not supported for use in DirectQuery mode. For more information about limitations in DirectQuery models, see https://go.microsoft.com/fwlink/?LinkId=219172.
Example
The following sample formula creates a measure that obtains the last date, for the current context, when a sale was made in the Internet sales channel.
To see how this works, create a PivotTable and add the field CalendarYear to the Row Labels area of the PivotTable. Then add a measure, named LastSaleDate, using the formula defined in the code section, to the Values area of the PivotTable.
=LASTDATE('InternetSales_USD'[SaleDateKey])
