Exclude current week

[brinky]

Good morning,

I'm trying to get all sales for the last eight weeks.
I manged to get the 8 week but would like to exclude the current week

Measure 3 = 
CALCULATE([QTY_Sales],
    FILTER(SalesData,
     DATEDIFF(SalesData[DDate],TODAY(),WEEK) < 8 
    )
)

Any ideas?

Thanks in advance.

Hi @brinky ,

According to the description, you may try this:

Measure = 
CALCULATE (
    [QTY_Sales],
    FILTER (
        'SalesData',
        DATEDIFF ( 'SalesData'[Date], TODAY (), WEEK ) < 8
            && DATEDIFF ( 'SalesData'[Date], TODAY (), WEEK ) >= 1
    )
)

If it does not make sense, please provide me with more details about your table and your problem or share me with your pbix file after removing sensitive data.

Hey @brinky ,

based on my answer in this thread: Solved: Re: Week commencing in DAX - Microsoft Power BI Community

You can create something like this:

some weeks in the past =
var __today = TODAY()
var startOfWeeek = __today  - WEEKDAY( __today , 2 ) + 1 //assuming the week starts with Monday
var endOfWeek = __today + 7 - WEEKDAY( __today , 2 ) 
var numberOfPreviousWeeks = 1
var startOfPrevWeeeks = startOfWeeek - 7 * numberOfPreviousWeeks
var endOfPrevWeek = endOfWeek - 7

return
CALCULATE(
    [Actual Sales]
    , DATESBETWEEN( 'DimDate'[Datekey] , startOfPrevWeeeks , endOfPrevWeek )
)

Hopefully, this provides something to tackle your challenge.

Regards,

Tom
