Rolling 90 Day Avg

I've combed the forums and have tried to replicate what others have done but with no luck. I need to show actual dollars won over a rolling 90 day average.   I wrote a measure to show Today's date ...

Hi bhmiller89,

As I tested, the syntax of the measure is right, and get the expected result. This measure will calculate the Total services since the last 90 days. But for your requirement, the TODAY() function is inappropriate. I try to reproduce your scenario, and get expected result as followings.

The first screenshot is the sample data.

 

Then I create a measure to calculate the rolling 90 day average and get the result shown in second snapshot.

90days_average = DIVIDE(CALCULATE(SUM(Test[Value]),FILTER(ALL(Test),AND(Test[Date]<=MAX(Test[Date]),Test[Date]>(MAX(Test[Date])-90)))),90)

 


For instance, for 2016/3/31, the measure will calculate the average during 2016/1/2-2016/3/31, for 2016/4/1, the measure will calculate the average during 2016/1/3-2016/4/1.

If you have any other issue, please feel free to ask.

Best Regards,
Angelia

    Hi v-huizhn-msft,

     

    This makes sense. However, I don't need the ability to look at rolling totals on historic dates, only in real time. So if I look at the Dashboard this morning with refreshed data, I would see a rolling total 90 days before today, and then when I check tomorrow it will be 90 days from tomorrow. 

     

    I'm really bad at using "date" tables and was trying to avoid that if possible!

      Hi bhmiller89,

      You'd better create a slicer to filter the date, please see the following screenshot, when you select the 2016/5/1, it will return the sum total of last 90 days from 2016/5/1.
