你可以这样写Measure

Measure = 
VAR _maxDate =
    MAX ( 'Table'[Date] )
VAR _prod =
    MAX ( 'Table'[Product] )
VAR _Amt =
    SUM ( 'Table'[Amount] )
VAR _immediatelyPrecedingDate =
    CALCULATE (
        MAX ( 'Table'[Date] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Product] = _prod && 'Table'[Date] < _maxDate )
    )
VAR _immediatelyPrecedingAmt =
    CALCULATE (
        SUM ( 'Table'[Amount] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Date] = _immediatelyPrecedingDate
                && 'Table'[Product] = _prod
        )
    )
VAR _comp =
    IF ( _immediatelyPrecedingAmt < _Amt, "Yes", "No" )
RETURN
    _comp

或像这样的Calculated Column

Column = 
VAR _maxDate =
    CALCULATE ( MAX ( 'Table'[Date] ) )
VAR _prod =
    CALCULATE ( MAX ( 'Table'[Product] ) )
VAR _Amt =
    CALCULATE ( SUM ( 'Table'[Amount] ) )
VAR _immediatelyPrecedingDate =
    CALCULATE (
        MAX ( 'Table'[Date] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Product] = _prod && 'Table'[Date] < _maxDate )
    )
VAR _immediatelyPrecedingAmt =
    CALCULATE (
        SUM ( 'Table'[Amount] ),
        FILTER (
            ALL ( 'Table' ),
            'Table'[Date] = _immediatelyPrecedingDate
                && 'Table'[Product] = _prod
        )
    )
VAR _comp =
    IF ( _immediatelyPrecedingAmt < _Amt, "Yes", "No" )
RETURN
    _comp
