Dynamic Slicer

Hello,

In key Measure, I have the current year=year(today()) and year before=current year - 1.

Also, I have a table Dim Calendar which contains dateskey for each day, the fiscalyear and other values.

In a slicer, we use the field FiscalYear.   We are interested only to have the current year and the year before
(2018, 2019).

In order to have a slicer which shows only the two last years, I need to use a filter and say FiscalYear equal or greater to 2018.

It works well.  However, in 2020, I will have to change the value into the filter.  Therefore, I wonder to know if there is a way to use the two above mentioned measure to filter the fiscal year.

Thanks in advance for your help
