Relative Value Between Dates

Hi badluckmath ,

Please try the following measures:

Today/ Yesterday =
VAR today_ =
    CALCULATE (
        SUM ( 'Table'[Quantidade] ),
        FILTER ( 'Table', 'Table'[Date] = TODAY () )
    )
VAR yesterday_ =
    CALCULATE (
        SUM ( 'Table'[Quantidade] ),
        FILTER ( 'Table', 'Table'[Date] = TODAY () - 1 )
    )
VAR NextMaxDate_ =
    MINX ( TOPN ( 2, ALL ( 'Table' ), 'Table'[Date], DESC ), 'Table'[Date] )
VAR NextDateQuan_ =
    CALCULATE (
        SUM ( 'Table'[Quantidade] ),
        FILTER ( 'Table', 'Table'[Date] = NextMaxDate_ )
    ) -- if there is no data yesterday, it calculates the value on next maximum date.
RETURN
    IF (
        ISBLANK ( yesterday_ ),
        DIVIDE ( today_, NextDateQuan_ ),
        DIVIDE ( today_, yesterday_ )
    )

This week/ Last Week =
VAR thisweek =
    CALCULATE (
        SUM ( 'Table'[Quantidade] ),
        FILTER ( 'Table', 'Table'[Week] = MAX ( 'Table'[Week] ) )
    )
VAR lastweek =
    CALCULATE (
        SUM ( 'Table'[Quantidade] ),
        FILTER ( 'Table', 'Table'[Week] = MAX ( 'Table'[Week] ) - 1 )
    )
RETURN
    DIVIDE ( thisweek, lastweek )

This Month/ Last Month =
VAR thismonth =
    CALCULATE (
        SUM ( 'Table'[Quantidade] ),
        FILTER ( 'Table', MONTH ( 'Table'[Date] ) = MONTH ( MAX ( 'Table'[Date] ) ) )
    )
VAR lastmonth =
    CALCULATE (
        SUM ( 'Table'[Quantidade] ),
        FILTER (
            'Table',
            MONTH ( 'Table'[Date] )
                = MONTH ( MAX ( 'Table'[Date] ) ) - 1
        )
    )
RETURN
    DIVIDE ( thismonth, lastmonth )

If you don't want to calculate percentage, please try this:

This week VS Last Week =
VAR thisweek =
    CALCULATE (
        SUM ( 'Table'[Quantidade] ),
        FILTER ( 'Table', 'Table'[Week] = MAX ( 'Table'[Week] ) )
    )
VAR lastweek =
    CALCULATE (
        SUM ( 'Table'[Quantidade] ),
        FILTER ( 'Table', 'Table'[Week] = MAX ( 'Table'[Week] ) - 1 )
    )
RETURN
    thisweek & " VS " & lastweek
