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.
The result table includes only dates that exist in the dates column.
If the dates in the current context do not form a contiguous interval, the function returns an error.
This DAX function is not supported for use in DirectQuery mode.
