    Hi Analitika 

    Try this code.

    Difference = 
VAR _MaxDate =
    MAXX (
        FILTER (
            'x',
            'x'[date] > EARLIER ( 'x'[date] )
                && 'x'[ID] = EARLIER ( 'x'[ID] )
        ),
        [date]
    )
VAR _CRE =
    SUMX (
        FILTER ( ALL ( 'x' ), 'x'[date] = _MaxDate && 'x'[ID] = EARLIER ( 'x'[ID] ) ),
        [CRE]
    )
RETURN
    IF ( x[DET] <> 0, _CRE - x[DET], BLANK () )

    Result is as below.

Hi Analitika 

Try this code.

Difference = 
VAR _MaxDate =
    MAXX (
        FILTER (
            'x',
            'x'[date] > EARLIER ( 'x'[date] )
                && 'x'[ID] = EARLIER ( 'x'[ID] )
        ),
        [date]
    )
VAR _CRE =
    SUMX (
        FILTER ( ALL ( 'x' ), 'x'[date] = _MaxDate && 'x'[ID] = EARLIER ( 'x'[ID] ) ),
        [CRE]
    )
RETURN
    IF ( x[DET] <> 0, _CRE - x[DET], BLANK () )

Result is as below.
