How can I visualize the sum of values of 3 months before for each month?

[garluc93]

I have uptaded a sample of my data here: SAMPLE PBIX 

I need a matrix with customers on rows, date on column and the sum of 3 previous month of test[boolean] for each month. Do you have an idea? I have tried some measures but power bi does not display anything

My test:

sumlast3months =CALCULATE(SUM(data2[BOOLEAN]);DATEADD(TIMELINKTABLE[Date];-3;MONTH))

I think this is the solution

sumlast3months =
var month3=CALCULATE(
SUM(data2[BOOLEAN]);
DATEADD(TIMELINKTABLE[Date];-3;MONTH))
var month2=CALCULATE(
SUM(data2[BOOLEAN]);
DATEADD(TIMELINKTABLE[Date];-2;MONTH))

var month1=CALCULATE(SUM(data2[BOOLEAN]);
DATEADD(TIMELINKTABLE[Date];-2;MONTH))

return
month1+month2+month3

Try

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