Again, please a full example. This is completely unclear what your problem is.

@saurabhtd This works well if you have disconnected date dimension table

Measure = 
VAR _selectedDate = Today() //SELECTEDVALUE(dimDate[Date])
VAR _startDate = (_selectedDate-(WEEKDAY(_selectedDate,2)-1))-7
VAR _pystartDate = DATE(YEAR(_startDate)-1,MONTH(_startDate),DAY(_startDate))
VAR _endDate = _startDate+6
VAR _pyendDate = DATE(YEAR(_endDate)-1,MONTH(_endDate),DAY(_endDate))
RETURN  CALCULATE(SUM(Table[Sales]),Table[Date] >= _pystartDate && Table[Date] <= _pyendDate)

I have connected calendar table. So this doesn't work.
