PARALLELPERIOD VS DATEADD DAX functions

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.

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.
