Filter Days for last 2 week, excluding the current week ( Week starts from Monday)

[Anonymous]

Hello All, 

I want to filter last 2 weeks data, which should not include the current week. 

The week starts from Monday. 

This is how my calender table looks like

I need a matrix which shows last two weeks- 

But I am getting the 2021W16 , which is wrong

Can someone please help me with writing DAX. 

Any help would be appreciated.

@Anonymous , with help from date table

new columns in Date table 
Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)
OR
Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format

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

Last 2 weeks before current  = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]>=max('Date'[Week Rank])-3 && 'Date'[Week Rank]<=max('Date'[Week Rank])-1 ))

Hi @amitchandak 

Thanks for the reply. that worked. But can you help me with how do I create a table out of a measure ?
I am not able to create the table as the measure aggregates the values.

I need to see it per week. I don't want the values per week aggregated/summed. 

Can you please help ?

Thanks again in advance.
