Filters Compare two years, first one selected, the second one automated

[tsynenkyy]

Hi guys,

I have the following two filters:

You select both years and the measures works perfectly, but the next step is to automatize the "Year & Month Comparison" so when I select "Year & Month" = 2022   then automatically the filter "Year & Month Comparison" will select 2021.

Relationship between both time tables:

thanks

@tsynenkyy , with help from a date table last year can be

Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-1,Year))
Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),SAMEPERIODLASTYEAR('Date'[Date]))

//Only year vs Year, not a level below

This Year = CALCULATE(sum('Table'[Qty]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])))
Last Year = CALCULATE(sum('Table'[Qty]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])-1))
diff = [This Year]-[Last Year ]
diff % = divide([This Year]-[Last Year ],[Last Year ])

Hi, many thanks for your asnwer but I think this is not what I need, actually I think that what I need is not possible in Power BI.

I need to keep the functionality I have (select both years) but when I firstly select the "Year and Month" it must automatically change the value on my other filter "year and month comparison) to YearSelected - 1, but I think is not possible that.
