Balhemkan , Try like example with help from date table

YTD =
var _max = eomonth(maxx(allselected([Date]), 'Date'[Date]),-1)
return
if(max('Date'[Date])<=_max, calculate(Sum('order'[Qty]),DATESYTD('Date'[Date])), blank())
//or
//calculate(Sum('order'[Qty]),DATESYTD('Date'[Date]),filter('Date','Date'[Date]<=_max))
//calculate(TOTALYTD(Sum('order'[Qty]),'Date'[Date]),filter('Date','Date'[Date]<=_max))

LYTD QTY forced=
var _max = eomonth(maxx(allselected([Date]), 'Date'[Date]),-13)
return
if(max('Date'[Date])<=_max, CALCULATE(Sum('order'[Qty]),DATESYTD(dateadd('Date'[Date],-1,year)),'Date'[Date]<=_max), blank())
//OR
//CALCULATE(Sum('order'[Qty]),DATESYTD(dateadd('Date'[Date],-1,year)),'Date'[Date]<=_max)
//TOTALYTD(Sum('order'[Qty]),dateadd('Date'[Date],-1,year),'Date'[Date]<=_max)
