What is the logic for getting last 5 weeks data in a measure even when there is a fiscal year change

New Fiscal year starts in February 1st. So far,I didn't use year column and only we used week,I could do easily by taking max of week number and getting 5 weeks back from that. But right now we have another fiscal year coming so I think year column needs to be clubbed with week to get unique year week number

 

Right now, that column looks like the below 

202248

202249

202250

202251

202252

202301

202302

 

Now I can't use max and subtract 5 to get last 5 weeks. How do I do this?

@Imagauthamam , If you want this based on today

 

Last 5 Week Today =
var _min1 = today() -WEEKDAY(today() ,2) -6 //Monday week start
var _max = _min1 +6

var _min = _min - 4*7
return CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

 

If you need based on selected value, ROlling 5 weeks data

 

You need columns

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

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

 

 

Last 5 weeks = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]>=max('Date'[Week Rank])-5 && 'Date'[Week Rank]<=max('Date'[Week Rank])))

 

But if you need 5 week trend when select 1 week, you need one more date table (independent)

 

//Date1 is independent Date table and Date is Joined
new measure =
var _max = max('Date'[Week Rank])
var _min = max('Date'[Week Rank]) -5
return
calculate( sum(Table[Value]), filter('Date', 'Date'[Week Rank] >=_min && 'Date'[Week Rank] <=_max))
