Return data from specified time interval in all rows in a calculated column

souvik900766 — Sat, 10 Jul 2021 02:38:29 GMT

Hi !

My Data:-

Year	Month	CY	2018
2019	Jan,19	784003.6
2020	Jan,20	796923
2021	Jan,21	912686.3
2018	Jan,18	754578.3

I want to return year 2018 CY Value i.e. 754578 in 2018 Column in all rows.
The calculation should be based on latest month for e.g.
MAX(Month),dateadd(month,-3,year)
So, here I want to find from Jan, 2021, to 3 years prior data.
I tried with this options but not working.

Thanks in advance !

Hi,

What exactly is your end objective? Also, why are you writing this as a calculated column formula (and not as a measure)?

Hi,

This calculated column formula works

CALCULATE(SUM(Data[CY]),FILTER(Data,Data[Month]=EDATE(MAX(Data[Month]),-36)&&Data[Month]=EDATE(MAX(Data[Month]),-36)))

Hope this helps.

Possibly // an empty set depending on // your data. filter( T, T[Year] = 2018 && T[Month] = CurrentMonth ), T[CY] ) return _2018Value

Your formula is different than mine. That's the first thing. Secondly, you asked about the year 2018. This is what I gave you. The month you put in my formula must be the plain month without the year attached, of course. Please create a column that will store just the plain month as a number (1,...,12) or a name.
