How to calculate percentage per year

[Anonymous]

Hi, 
I'm working on a report of sales from last year to know.
I created a measure that shows me the percentage of sales of each product from the grand total but Now I have information of 2019 and this measure sums all units solds from 2018 and 2019

% VENTAS TOTALES DEL AÑO = sum(Consolidado2018[UNIDADES])/sumx(all(Consolidado2018),Consolidado2018[UNIDADES])

So what I need is a new measure that shows me the percentage of sales of 2018 when I select 2018 and 2019.

Hope you can help me. 

Thank you
