Prior week and Current week display

Amjad1002 , Based on today

WTD Today =
var _min = TODAY() -WEEKDAY(TODAY(),2) +1 //Monday week start
var _max = today()
return CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

LWTD Today =
var _min = TODAY() -WEEKDAY(TODAY(),2) -6 //Monday week start
var _max = today() -7
return CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

LYWTD Today =

return CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

This Week Today =
var _min = today() -WEEKDAY(today() ,2) +1 //Monday week start
var _max = _min +6
return CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

Based on selected dates, you need column in date table

Have these new columns in Date Table, Week Rank is Important in Date/Week Table

Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)
OR
Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format

These measures can help
This Week = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))
