Typically same week is 364 days behind

Week Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-364,Day))

You can also refer this file which use week rank -https://www.dropbox.com/s/d9898a48e76wmvl/sales_analytics_weekWise.pbix?dl=0

The same week would be 52 ranks less  or you can use

Also you can modify this formula and use

Measure TD = 
var _max = maxx(table[Week])//format of 201901
var _week = right([WeekYear],2)
var _year= left([WeekYear],4)
return
calculate(table[Value], filter(all(Table), Table[Year]=_year && Table[week No] <=_week))

Measure LTD = 
var _max = maxx(table[Week])//format of 201901
var _week = right([WeekYear],2)
var _year= left([WeekYear],4)-1
return
= calculate(table[Value], filter(all(Table), Table[Year]=_year&& Table[week No] <=_week))

@amitchandak I think you  missed the point or I could be totally wrong, @Anonymous there is no date column in her model, just year and week.

@Anonymous try this, again might need tweaking, add a measure

Prev Year and Week = 
VAR __PrevYear = MAX ( Table[Year] ) - 1
VAR __Week = MAX ( Table[Week] )
RETURN
CALCULATE ( SUM ( Table[Amount] ), ALL ( Table ), Table[Year] = __PrevYear, Table[Week] = __Week ) 

replace table and column name as per your model. 

Would appreciate Kudos 🙂 if my solution helped.
