    Hi Anonymous ,

    Sorry about that, try this:

    myMeasure = 
VAR _monthNumberCurrent =    MAX ( mytable[monthNumber] ) //get the month number from this row

var _thisMonthFlag = MAX(myTable[Flag])
VAR _prevMonthNumber =
    CALCULATE (
        MAX ( mytable[monthNumber] ),
        FILTER ( ALL ( myTable ), myTable[monthNumber] < _monthNumberCurrent )
    ) //filter the table to all month numbers less than this month number, and get the max value which is the month before

var _lastMonthFlag = CALCULATE(MAX(myTable[Flag]),FILTER(ALL(myTable),myTable[MonthNumber]=_prevMonthNumber))

RETURN
    DIVIDE ( _thisMonthFlag + _lastMonthFlag, IF(_lastMonthFlag = 0,1,2 ))


    Let me know if you have any questions.

    If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos 👍are nice too.

Hi Nathaniel_C ,

Thanks for this.

I am actually looking for average of [Flag] on those months ...

In the timeline on the right bottom corner ...
For February: it should be (5+4) / 2 = 4.5
For March: (4+3)/2 = 3.5

The final measure will be 2 months rolling average ...

Many thanks
