Precedence filter or SAMEPERIODLASTYEAR?

[Anonymous]

I see in a .pbix  the next filter page:   IsCurrentFY is 1

And… I also have the next measure for Last Year:   CALCULATE( xyz, SAMEPERIODLASTYEAR( 'Date'[Date] ) )

The visualization displays correctly; comparing xyz this year vs last year… I am wondering…

Why  IsCurrentFY is 1  doesn’t take precedence? Is it that SAMEPERIODLASTYEAR overrides any filter?

@Anonymous , I not sure I clear with your question, but this calculation means

CALCULATE( xyz, SAMEPERIODLASTYEAR( 'Date'[Date] ) )

CALCULATE( xyz, filter(all('Date') , Date[Date] in <all last year date> ) )

Yes, correct. My question is, what happens when you have a filter that wants to only display this year's data and a function like SAMEPERIODLASTYEAR explicitly trying to fetch last year's data...
