    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.

    Best Regards,

Analitika , small change

 

Column =
VAR _0 = MAXX(FILTER('x','x'[date]<EARLIER('x'[date]) && 'x'[ID]= EARLIER('x'[ID])),[date])
VAR _1 = MAXX(FILTER('x','x'[date] =_1 && 'x'[ID]= EARLIER('x'[ID]) ),[cre])
return
if('x'[deb] <> 0,_1 - 'x'[deb], blank())
