Hi Experts

How would you amend the following messure to make all those month that are 01/01 irrespective of year return zero value as opposed to the previous month value.

Meaure =

PREVIOUSMonth =

IF(CALCULATE(SUM(Orders[Sales]),

        PREVIOUSMONTH(Orders[DDate]))=01/01,0,CALCULATE(SUM(Orders[Sales]),

        PREVIOUSMONTH(Orders[DDate])))

Not working

Hi, @Invesco ;

Try it.

PREVIOUSMonth =
IF (
    MONTH ( Orders[DDate] ) = 1
        && DAY ( Orders[DDate] ) = 1,
    0,
    CALCULATE ( SUM ( Orders[Sales] ), PREVIOUSMONTH ( Orders[DDate] ) )
)
