Calculating a dynamic 6 week run rate

[AdamRobC]

Hi,

I want to calculate a 6 week run rate measure that, based on a selected week, looks back at the previous 6 weeks and calculates the average for that measure.

E.g. if Week Index = 10 then the DAX would filter for all values in weeks 4 - 9 and divide by 6. This would be dynamic so whatever week I select it filters for the previous 6 weeks based on the index.

Any ideas?

Thanks,

Adam

@AdamRobC , a measure like

Last 6 weeks = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week index]>=max('Date'[Week index])-6 && 'Date'[Week index]<=max('Date'[Week index]))) /6

or

Last 6 weeks = CALCULATE(averageX(values('Date'[Week index]) , 'order'[Qty]), FILTER(ALL('Date'),'Date'[Week index]>=max('Date'[Week index])-6 && 'Date'[Week index]<=max('Date'[Week index])))

Amazing! I had to make a couple of slight edits using SELECTEDVALUE instead of MAX but got it working 🙂

6 Week Run Rate Visits = CALCULATE([Visits],FILTER(ALL('Calendar'),'Calendar'[Week Index]>=SELECTEDVALUE('Calendar'[Week Index])-6 && 'Calendar'[Week Index]<=SELECTEDVALUE('Calendar'[Week Index])-1))/6
