I'm currently trying to get a 12 month rolling sum for each month.
Year | Month | Count | 12 Month Rolling |
2017 | November | 20 | 20 |
2017 | December | 25 | 25 |
2018 | January | 30 | 30 |
2018 | February | 45 | 45 |
2018 | March | 22 | 22 |
2018 | April | 50 | 50 |
2018 | May | 35 | 35 |
2018 | June | 0 | 0 |
2018 | July | 5 | 5 |
2018 | August | 10 | 10 |
2018 | September | 40 | 40 |
2018 | October | 36 | 36 |
2018 | November | 14 | 14 |
2018 | December | 20 | 20 |
2019 | January | 31 | 31 |
2019 | February | 20 | 20 |
The measure I'm using to get this is:
12 Month Rolling=
VAR NumberofMonths= 12
VAR LastCurrentDate= MAX (Sheet1[Date])
VAR Period = DATESINPERIOD(Sheet1[Date],LastCurrentDate,-NumberofMonths,YEAR)
VAR Result = CALCULATE((DISTINCTCOUNT(Sheet1[Count])),Period)
VAR FirstDateInPeriod = MINX(Period,Sheet1[Date])
VAR LastDateWithSales = MAX(Sheet1[Date])
RETURN
IF(FirstDateInPeriod <= LastDateWithSales,Result)
However I was hoping to have the sum in the 12 month rolling column like this:
Year | Month | Count | 12 Month Rolling |
2017 | November | 20 | 332 |
2017 | December | 25 | 332 |
2018 | January | 30 | 338 |
2018 | February | 45 | 328 |
2018 | March | 22 | 283 |
2018 | April | 50 | 261 |
2018 | May | 35 | 211 |
2018 | June | 0 | 176 |
2018 | July | 5 | 176 |
2018 | August | 10 | 171 |
2018 | September | 40 | 161 |
2018 | October | 36 | 121 |
2018 | November | 14 | 85 |
2018 | December | 20 | 71 |
2019 | January | 31 | 51 |
2019 | February | 20 | 20 |
Any help on getting this rolling sum over 12 months would be greatly appreciated.
Thanks in advance

Hi @Niiru1 ,
You could add a date column in the table.
date = DATE('Table'[Year],'Table'[number of Month],1)
Then create a measure as below.
Measure = CALCULATE(SUM('Table'[Count]),FILTER(ALLSELECTED('Table'),'Table'[date]>=SELECTEDVALUE('Table'[date])&&'Table'[date]<=EDATE(SELECTEDVALUE('Table'[date]),12)))
Best Regards,
Jay
