Null value using measure in Power BI

[Analitika]

Hello,

I would like to ask how to fix this. I wanted to calculate the change between years but getting null value, Formula looks like this:

mokLY = 
IF( HASONEVALUE(PARDAVIMAI[year]) ,CALCULATE ( [moketina_suma],
    DATEADD (PARDAVIMAI[SUTP_DATA],-1,YEAR ) ) )

this formula generates null it is not depending on which year I select.

Hi @Analitika 

Maybe try to do something like this:

SumLY = CALCULATE ([moketina_suma], SAMEPERIODLASTYEAR (PARDAVIMAI[SUTP_DATA]))

[Analitika]

It is not what I am looking for. My point to get percent to see increase decrese comparing same period. So for this I used: 

mokLY = 
IF( HASONEVALUE(PARDAVIMAI[year]) ,CALCULATE ( [moketina_suma],
    DATEADD (PARDAVIMAI[SUTP_DATA],-1,YEAR ) ) )

@Analitika 

You can still use my measure.

Do something like this:

Diff to last year % = DIVIDE ( [moketina_suma], [SumLY],0)-1

This will show you the year over year percentage difference for the period you specify in a slicer.
So if you choose full 2021 year it will show you the difference to full 2020.

Getting this error:

In SAMEPERIODLASTYEAR function use the date column from your date table instead of PARDAVIMAI[SUTP_DATA].

Hi, it also wrong:

All time diff is -1. But sum is different in 2021 and 2022 years. I also checked that there is a relationship between date and table2 tables. But getting wrong answer.

@Analitika 

Maybe try to post some sample data and expected result.
It would be easier to work on.

Expected result that I could percents how sales increased or decresed per period.

I use formula but it doesn't work.
