YoY in incompleted year

[daniel0920bu]

Hi - 

Here is my expected result. 

Date	Sum	Sum (last year)	YoY diff
2019 Jun	150	-	-
2020 Jun	100	150	-50
2021 Jun	120	100	+20
2022 (Apr)	80	120	-40

My question is that how to create a measure to calculate YoY differences for 2022 when the year isn't completed yet? If I use dateadd/sameperiodlastyear function, power bi could only compare the value of 2021 Apr, which this data is absent (and it is not what I want).

Thanks a lot for your help!

Hi  @daniel0920bu ,

I created some data:

Here are the steps you can follow：

1. Create measure.

Flag =
var _1=MAXX(FILTER(ALL('Table'),YEAR('Table'[Date])=YEAR(MAX('Table'[Date]))),[Date])
return
IF(
    MONTH(MAX('Table'[Date]))=MONTH(_1),1,0)

Sum =
SUMX(FILTER(ALL('Table'),YEAR('Table'[Date])=YEAR(MAX('Table'[Date]))&&'Table'[Date]<=MAX('Table'[Date])),[amount])

Sum (last year) =
SUMX(FILTER(ALL('Table'),YEAR('Table'[Date])=YEAR(MAX('Table'[Date]))-1&&'Table'[Date]<=MAX('Table'[Date])),[amount])

YoY diff =
IF(
    [Sum (last year)]=BLANK(),BLANK(),
[Sum] - [Sum (last year)])

2. Place [Flag]in Filters, set is=1, apply filter.

3. Result:

When the last date is 2022.4:

Add a row of data for 2022.5 and the last date as 2022.5:

The results also change with the date:

You can create a measure like

YOY Diff =
var currentDate = MAX('Date'[Date])
var lastYearTotal = CALCULATE( [Total measure], REMOVEFILTERS('Date'), 'Date'[Year] = YEAR(currentDate) - 1)
var currentYearTotal = [Total measure]
return currentYearTotal - lastYearTotal
