Help calculating a 7 day running total column
I have a table in PowerBI that has the column "Date" and "Sales". I want to create a measure and display it in a table that computes a rolling 7 day total of the "Sales" column. To be clear, I want to see this over time, I do not want it for a single day, I want to create a table exactly like I am showing below, thanks!
| Date | Sales | Running 7 Day Total |
| 1/1/2020 | 72 | |
| 1/2/2020 | 5 | |
| 1/3/2020 | 34 | |
| 1/4/2020 | 45 | |
| 1/5/2020 | 81 | |
| 1/6/2020 | 60 | |
| 1/7/2020 | 63 | 360 |
| 1/8/2020 | 6 | 294 |
| 1/9/2020 | 53 | 342 |
| 1/10/2020 | 30 | 338 |
| 1/11/2020 | 32 | 325 |
| 1/12/2020 | 35 | 279 |
| 1/13/2020 | 82 | 301 |
| 1/14/2020 | 55 | 293 |
| 1/15/2020 | 99 | 386 |
| 1/16/2020 | 97 | 430 |
| 1/17/2020 | 100 | 500 |
| 1/18/2020 | 54 | 522 |
Hi,
Assuming there is a sale recorded for everyday, try this:
- Create a Calendar Table
- Build a relationship from the Date column of the Data Table to the Date column of the Calendar Table
- To your visual, drag the Date field from the Calendar Table
- Write these measures
Total sales = SUM(Data[Sales])
7 days rolling sales = CALCULATE([Totalsales],DATESBETWEEN(Calendar[Date],MIN(Calendar[Date])-6,MIN(Calendar[Date])))
Hope this helps.

I can't think of a time intelligence measure for that. See if my Time Intelligence the Hard Way provides a different way of accomplishing what you are going for.

In case you use date calendar
Rolling 7 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date Filer],MAX(Sales[Sales Date]),-7,MONTH)) Rolling 7 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date Filer],MAX(Date[Date]),-7,MONTH))To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
