Need to convert the tableau query to DAX

I need to convert this tableau calculated field to Power BI query. Help with this is needed.

if isnull[Actual date]

then [planned date]

else [Actual date]

How do I convert this to PBI measure?

Measure =
VAR ActualDate = [Actual Date]
VAR PlannedDate = [Planned Date]
RETURN
IF(ISBLANK(ActualDate), PlannedDate, ActualDate)
