Write values in column from last year

[dirkkoch]

Hi,

I am struggling with the following. I want to create a new column, in which I want to show the value (column 3 "Anzahl Lieferungen") from last year's date (column 1 "Datum Auswertung" - 1 year) considering the value in column B ("Route", eg. Seefracht, Kurier, Luftfracht). Which formula must I use in DAX to do that?

@dirkkoch  can you please provide some sample data and desired output for those candidates?

@dirkkoch 

calculatedColumn=MAXX(filter(t1,t1[Route]=earlier(t1[Route])&&t1[Datum Auswertung]=earlier(t1[Datum Auswertung])-365),t1[Anzahl Lieferungen])

@smpa01  thank you for the support. This works fine. Since there are also leap years with 366 days a year. How can I take care of this without having to manually adjust?

Hi @dirkkoch 

Use EDATE([date column], -12) function to get the same date in last year. This would not have that problem. For leap years, it will get last year's Feb 28th's value for this leap year's Feb 29th. 

calculatedColumn =
MAXX (
    FILTER (
        t1,
        t1[Route] = EARLIER ( t1[Route] )
            && t1[Datum Auswertung] = EDATE ( EARLIER ( t1[Datum Auswertung] ), -12 )
    ),
    t1[Anzahl Lieferungen]
)
