LASTDATE

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

  • 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.
  • 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 function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

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])
