Rolling average Last Month and Current Month

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.
