Calculate 3 months rolling

[Tvarberg]

Looking for advice on how to calculate 3 months rolling average when data are 0 for some months.

I would like to calculate for Full Year but actual data should be used when available.

The first calculation should come in April and use Data for AVERAGE JAN, FEB, MAR

Hi @Tvarberg ,

I have created a simple sample, please refer to my pbix file to see if it helps you.

result =
VAR _1 =
    EDATE ( MAX ( 'Table'[date] ), -3 )
VAR _year =
    YEAR ( _1 )
VAR _month =
    MONTH ( _1 )
VAR _date =
    DATE ( _year, _month, 1 )
VAR _nowdate =
    MAX ( 'Table'[date] )
RETURN
    CALCULATE (
        AVERAGE ( 'Table'[value] ),
        FILTER ( ALL ( 'Table' ), 'Table'[date] >= _date && 'Table'[date] < _nowdate )
    )

Hi,

Try this approach

1. Create a Calendar Table with calculated column formulas for Year, Month name and Month number.  Sort the Month name column by the Month number
2. Create a relationship (Many to One and Single) from the Date column of your Data Table to the Date column of the Calendar Table
3. To your visual, drag Year and Month name from the Calendar Table
4. Write these measures

Measure = sum(Data[Revenue])

Rolling average = averagex(SUMMARIZE(calculatetable(Calendar,datesbetween(calendar[date],minx(all(calendar),calendar[date]),max(calendar[date]))),calendar[year],calendar[month name],"ABCD",[Measure]),[ABCD])

Hope this helps.
