Week to date for no ended week

[paolomint]

Dear all,

I'm working on a Week to date calculation a little bit different respect to the tutorials I found on internet.

For eg. https://radacad.com/week-to-date-calculation-in-power-bi-with-dax

My model is very easy: a raw sales table with all the transictions, a datatable

I need to compare the total sales of this week over the total sales of the same period of the previous week.

Example: Today is Wednesday, I need to compare:

- sales from monday to wednesday of last week 

- sales from monday to wednesday of this week

SHOP	PREV WEEK (monday to wednesday)	THIS WEEK (monday to wednesday)
ROME	2.000	1.800
PARIS	3.000	3.300

I hope someone can help me

Bye

Paolo

@paolomint based on that post, you should calculate the start and end date by subtracting out of it and that will give you the previous week's date, and then it should work.

something like this, taking the DAX from the post:

Week to Date Sales = 
var CurrentDate=LASTDATE(DimDate[FullDateAlternateKey])
var DayNumberOfWeek=WEEKDAY(LASTDATE(DimDate[FullDateAlternateKey]),3)
var __startDate = DATEADD(
    CurrentDate,
    -1*DayNumberOfWeek,
    DAY) - 7
var __endDate = CurrentDate - 7
return
CALCULATE(
    SUM(FactInternetSales[SalesAmount]),
DATESBETWEEN(
    DimDate[FullDateAlternateKey], __startDate, __endDate 
)
)
