@Paulyeo11 

do you only consider month? Since i see you circle all Oct and Nov sales amount for both 2019 and 2020.

if I did not misunderstand your request. you can try this

Measure 2 = 
VAR _max=max('SALES'[date])
VAR last1=month(_max)-1
VAR last2=month(_max)-2
RETURN CALCULATE(sum(SALES[sales]),FILTER(SALES,month(SALES[date])in {last1,last2}))

Hi Ryan

@Paulyeo11 , Try rolling formula, With date table

Rolling 12 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-12,MONTH))

If means every month will display 2 months of data '

In case you want two month with any selected date -https://www.youtube.com/watch?v=duMSovyosXE

@Paulyeo11  , YTD was other topics or

You can have rolling of any months by replacing values

Rolling 2 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-2,MONTH))

Rolling 3 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-3,MONTH))
