Hi daominhtri

Try this for your column:

WorkingDayID2 =
COUNTROWS (
    FILTER (
        Table1;
        Table1[Date] <= EARLIER ( Table1[Date] ) && Table1[DayType] = "Workingday"
    )
)

daominhtri  Create following calculation columns. Please see the attached file for your reference.

Working Day ID1 = 
COUNTROWS (
    FILTER (
        Sheet1,
        Sheet1[Date] <= EARLIER ( Sheet1[Date] ) && Sheet1[Type] = "Working"
    )
)

Working Day ID2 = IF(Sheet1[Type]="Working",Sheet1[Working Day ID1],BLANK())
