How to calculate last year's score without using a date table?

[Gjakova]

Hi there,

I'm doing a report where I don't have a date calendar. So I can't use TI functions like SAMEPERIODLASTYEAR or DATEADD, because the only thing that is relevant in my data are the seasons e.g. season 2002/2003, 2003/2004 ..... 2020/2021

In this scenario, when creating a KPI, how can I create a measure that changes dynamically based on the filters that I select? So when I filter on 2018/2019.

My KPI shows that year + previous year (2017/2018). When I select 2006/2007, my KPI shows that year + previous year (2005/2006).

Someone who has an idea?

Hi @Gjakova 

Try this measure.

Current+PrevYear = 
VAR selectedYearKey = SELECTEDVALUE(Years[Year_KEY])//Decide how will you handle no selection and mutiple selection
VAR PrevYearKey = selectedYearKey - 1
Return SUMX(
    FILTER(ALL(Scores), Scores[Year_KEY] in {selectedYearKey, PrevYearKey})
    , Scores[Score])

Hope this helps.

Please mark it as a solution if it serves the purpose.

Thanks

@Gjakova , Prefer to have separate Year table atleast , Try to use numeric year or rank to get that.

With date/year table

This Year = CALCULATE(sum('order'[Qty]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])))
Last Year = CALCULATE(sum('order'[Qty]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])-1))

check option of without using time intelligence

Hi @amitchandak, unfortunalety I can't work with date tables. I also don't work with full years, but with seasons. So season 2017/2018 etc. 

If you have time, could you perhaps try your method out with my sample data? I tried it, but I can't get it to work. Hope to hear from you!

@Gjakova if you have number field that identifies the order of the year, you can achieve this using following measure

Previous Year = 
VAR __id = MAX ( TableYear[Id] ) 
VAR __prevId = __id - 1
RETURN
CALCULATE ( SUM ( Table[Amount] ), TableYear[Id] = __prevId )

I tried your answer, but it partly works @parry2k 
When I put my measure in a table and also the years, than it only shows the total previous, but the years stay blank.

Could you perhaps try it out with my sample data and see if you manage to make it work? If it works then I can replicate that same trick on my real dataset. Many thanks in advance!
