Filter year/quarter in a calculation

dp32 , if you can use time intelligence that would be best . With a date table

QTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESQTD(('Date'[Date])))
Last QTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESQTD(dateadd('Date'[Date],-1,QUARTER)))

another way is qtr rank/ with Qtr/date table

Qtr Rank = RANKX(all('Date'),'Date'[Qtr Start date],,ASC,Dense)
This Qtr = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Qtr Rank]=max('Date'[Qtr Rank])))
Last Qtr = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Qtr Rank]=max('Date'[Qtr Rank])-1))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
