Hi @Anonymous ,

We can create measures using following measure to meet your requirement:

1-MonthSamePeriod =
CALCULATE (
    SUM ( 'Table'[Sales] ),
    FILTER (
        'Table',
        AND (
            [Date]
                >= DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ) - 1, 1 ),
            [Date]
                <= DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ) - 1, DAY ( TODAY () ) - 1 )
        )
    )
)

2-MonthSamePeriod =
CALCULATE (
    SUM ( 'Table'[Sales] ),
    FILTER (
        'Table',
        AND (
            [Date]
                >= DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ) - 2, 1 ),
            [Date]
                <= DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ) - 2, DAY ( TODAY () ) - 1 )
        )
    )
)

1-MonthSamePeriod =
CALCULATE (
    SUM ( 'Table'[Sales] ),
    FILTER (
        'Table',
        AND (
            [Date]
                >= DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ) - 3, 1 ),
            [Date]
                <= DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ) - 3, DAY ( TODAY () ) - 1 )
        )
    )
)

You can also try datesmtd

Last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-12,MONTH)))

I believe you want something like:

SUMX('Table',PARALLELPERIOD('Calendar'[Date],-1,MONTH),[Column)
