Previous Year average and 2 year average

[micsafdas]

Hello!

I'm stuck and it would be great if you Experts could help me.

I do have a measure which calculates the monthly rents. What I would need is a average bar for the last and the second to last year.

The measure to calculate the monthly rent for reference:

Rent actual =

CALCULATE(SUM('Erlöse'[Betrag]); 'Erlöse'[Positionsart] IN { "Miete" })

If you need anything else to answer the question, I'm happy to share.

Thanks in advance!

Hi @micsafdas ，

You need 2 measures as below:

Last 2 years average = CALCULATE(AVERAGE('Table'[Value]),FILTER(CALCULATETABLE(ALLSELECTED('Table'),ALL('Table'[Date])),'Table'[Date].[Year]=YEAR(MAX('Table'[Date]))-2))

Previous year average = CALCULATE(AVERAGE('Table'[Value]),FILTER(CALCULATETABLE(ALLSELECTED('Table'),ALL('Table'[Date])),'Table'[Date].[Year]=YEAR(MAX('Table'[Date]))-1))

Finally you will see :

As I can't seem to be able to attach the graphic in the original post here what I am looking for.

In case you have date dimension

Last YTD complete Sales = CALCULATE(Avergae(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year)),"12/31"))

Last to last YTD complete Sales = CALCULATE(Avergae(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-2,Year)),"12/31"))

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.

@amitchandak 

Thanks for your post! This seems promising, but I didn't get the expected result back.

I probably explained it not to the fully extent.

I need (looking from 2019) the average of 2018, namely from 01.01.18 - 31.12.18 and from 2017 (vice versa)

No year to date calculations.

Btw, I do have a date table. To give it some "flesh", I uploaded the basic pbix which translates to the big pbix.

https://www.dropbox.com/s/u4wmq7puu5mzl05/Showcase.pbix?dl=0

I would expect the "Previous Year Average" to be at 4333 in 2018, as the sum of 2017 is 52K.

Thanks also!

I couldn't get your code to work though. It doesn't seem to understand this part:

Datumstabelle[Date].[Year]

The [Year] seems to be the problem. Why so?

Thanks so far you two!

I managed to solve it my self, once I got inspired by amitchandak's solution. 🙂

Its

Average last year = CALCULATE(SUM('Erlöse'[Betrag])/12;PREVIOUSYEAR(Datumstabelle[Date]);'Erlöse'[Positionsart] IN { "Miete" } )

and

Average second to last year = CALCULATE(SUM('Erlöse'[Betrag])/12;PARALLELPERIOD(Datumstabelle[Date];-2;YEAR);'Erlöse'[Positionsart] IN { "Miete" } )

Simple as that... ^^

Thanks all

If you want sum first at month level and the Average

Avergaex(summarize(CALCULATETABLE('Erlöse', DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year)),"12/31"), 'Erlöse'[Positionsart] IN { "Miete" })
	,date[month-year],"_sum",SUM('Erlöse'[Betrag])),_sum)
