Date measure 2 months ago (2020 data in 2021) Year -1 (2019)

[Nick2358]

Hello everyone,

Here is my problem today.

I have the measure below:

2020_2_Months_Ago =

var current_month = eomonth(TODAY(),-2)

return CALCULATE(SUM('Conso Bdgt 2020'[SUM]), FILTER('Dates', eomonth('Dates'[Date],0) = current_month))

I give me numbers that we track monthly that's 2 months back (since we are in January 2021 it's the number from November 2020).

However we compare it we the previous year number (which is 2019 but we are in 2021) and I can't find the solution even after trying a couple of things.

I'm pretty sure there is a "Year() -1" to be added somewhere but can't find how... 

Also once we get in March 2021 would the solution still work to have 2020 number (and not 2019 anymore).

I hope that makes sense,

Thanks in advance for your help,

Nick

You can use the time intelligence function to achieve it, try the following measure You can change the number of months as necessary, I have entered -2. If you need 14 months back,m add -14.

2020_2_Months_Ago = 
CALCULATE(
    SUM('Conso Bdgt 2020'[SUM]), 
    DATEADD(
        'Dates'[Date],
        -2,
        MONTH 
    )
)
