Hi,
I'm sure someone has asked this before but I've trawled through a heap of posts and can't quite find one that works for me.
I have a date slicer with start and end dates, and I have the below measure which gives me the average sales quantity over the last 8 weeks.
Qty Avg 8Wks =
VAR previousWeekDate =
TODAY () - WEEKDAY ( TODAY (), 1 )
RETURN
CALCULATE (
SUM ( ItemSales[Qty] ),
FILTER (
ItemSales,
ItemSales[WkStartDate] <= previousWeekDate
&& ItemSales[WkStartDate] >= ( previousWeekDate - 56 )
)
) / 8
The measure gives me the last 8 weeks average quantity from today, but I want it to give me the last 8 weeks from the end date of the slicer selection.
Can anyone help please?
Thanks,
Michael

Hi @mboucher_rcr ,
According to your description, as in your formula below, you specify the end date is the closest Saturday before today, not the end date of the slicer selection.
VAR previousWeekDate =
TODAY () - WEEKDAY ( TODAY (), 1 )
Modify you formula like this:
Qty Avg 8Wks =
VAR SelectedDay =
MAXX ( ALLSELECTED ( 'Date' ), 'Date'[Date] )
VAR previousWeekDate =
SelectedDay - WEEKDAY ( SelectedDay, 1 )
RETURN
CALCULATE (
SUM ( ItemSales[Qty] ),
FILTER (
ItemSales,
ItemSales[WkStartDate] <= previousWeekDate
&& ItemSales[WkStartDate] >= ( previousWeekDate - 56 )
)
) / 8
Get the correct result in my sample.
I attach my sample below for reference.

Hi,
Create a Calendar Table with a relationship (Many to One and Single) from the WkStartDate column of the ItemSales table to the Date column of the Calendar Table. Write this measure:
= CALCULATE(SUM(ItemSales[Qty]),DATESBETWEEN('Calendar'[Date],max('Calendar'[Date])-56,max('Calendar'[Date])))/8
Hope this helps.
Please define what you mean by "week" . Ideally you have a calendar table with week numbers. How do you handle transitions between (fiscal) years ? Say, "today" is February 1. What's your definition of "past 8 weeks" in that scenario?
