Have Sum costs by year and the costs of december of last year in a graph table

[Touix]

Hello,

I want to have in one graph Table the sum of the costs BY YEAR  and the costs for December of the last year.
I have for dimension Year, and for the 1st expression :  sum(Costs) --> Easy

But for the sum of the costs for december, this expression does not work : 

 sum({<Year={"$(=Addyears(Year,-1))"}, Month={12} >} Costs) 

I join you the sample file to help me.
Thank you veeery much !

Hi, try this in this situation.

Sum({<Year = {"$(=Year(Today())-1)"}, Month = {12}>} Costs )

Thank you for your answer.

But I think this will work only for the last year (ie. 2023) 

What if I need this for all the different year ?
