Week Is Not So Weak: WTD, Last WTD, and This Week vs Last Week

Objective: We would like to have WTD(Week Till Date) Last WTD and This Week vs  Last Week.

Dataset: We have taken Sales data. The data is from April 2018 till April 2020. We have created a date Calendar.

Steps: We create a Date Calendar With Monday to Sunday Week, with the following week-related columns.

 

 

 

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Number = WEEKNUM([Date],2)
Week = if('Date'[Week Number]<10,'Date'[Year]*10 & 'Date'[Week Number],'Date'[Year]&'Date'[Week Number])
Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)
Week name = [Week Start date] & " to "& [Week End date]
Weekday = WEEKDAY([Date],2)
WeekDay Name = FORMAT([Date],"ddd")

Now, to have Week Vs Last Week, we will use Week Rank, and the way to go is in the filter in the manner shown below:

FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])).

 

 

 

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))

For WTD, we will also use Weekday.

 

 

WTD = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank]) && 'Date'[Weekday] <=max('Date'[Weekday])))
LWTD = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -1) && 'Date'[Weekday] <=max('Date'[Weekday])))

Some of you has asked about last year. Few Options you can try.

LYWTD = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -52) && 'Date'[Weekday] <=max('Date'[Weekday])))

LYWTD = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Year]=(max('Date'[Year]) -1)
 && 'Date'[Week Number]=(max('Date'[Week Number]))
 && 'Date'[Weekday] <=max('Date'[Weekday])))

Last year same week and Last year Week

Last year same Week= CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -52)))

Last year Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Year]=(max('Date'[Year]) -1)
 && 'Date'[Week Number]=(max('Date'[Week Number]))
))
