calculate sales in the current month - N

[lawada]

hello

i want to create a measurethat calculate sales in the current month -2 

so for example if we are now in february 

i want to clalculate values in december(between 1-12-2020 and 31-12-2020)

and so on for current month-3 i want to get the values for november (between 1-11-2020 and 30-11-2020)

i would like this to be calculated dynamically so every time curremt month changes it will shift the number of months in the measurere automatically 

thank you,

@lawada , You can can use time intelligence

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))

not you can use what if measure https://docs.microsoft.com/en-us/power-bi/desktop-what-if

last Nth MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1* [Whatif] ,MONTH)))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.
