Hi! Could you guys give some help? I'm struggling here. I need to do a calculation between the current x last month, but I'll not use a date dimension to show each month in a table/graph. Because ...

    Hi Larry130,

     

    If I understand you correctly, the formula below should work in your scenario. :smileyhappy:

    PrevMonth =
VAR currentMonth =
    MONTH ( TODAY () )
VAR currentYear =
    YEAR ( TODAY () )
RETURN
    IF (
        currentMonth = 1,
        CALCULATE (
            [ID Alert],
            FILTER (
                ALL ( 'Calendar'[Date] ),
                YEAR ( 'Calendar'[Date] )
                    = currentYear - 1
                    && MONTH ( 'Calendar'[Date] ) = 12
            )
        ),
        CALCULATE (
            [ID Alert],
            FILTER (
                ALL ( 'Calendar'[Date] ),
                YEAR ( 'Calendar'[Date] ) = currentYear
                    && MONTH ( 'Calendar'[Date] )
                        = currentMonth - 1
            )
        )
    )

PERFECT! Thanks v-ljerr-msft

I've tried to use the SQLBI DAX Pattern for previous month, but was really hard to understand. Your way of doing it using VAR was way easier to understand. I'll study VAR!
