DAX or Power Query
Hi Everyone,
My question is, how do I find the sum of prior qty available in the past 13 weeks starting from today and going back 13 weeks.
Here is a mock dataset of the main table. This table is further connected to another table called 'Fiscal Calendar table' and is conencted via 'file date column'.
The method i used is:
| SKU | Province | prior qty available (cases) | total requested(cases) | total sold(cases) | file date |
| 1 | AB | 20 | 10 | 7 | 25/02/2022 |
| 2 | AB | 34 | 27 | 26 | 28/03/2022 |
| 3 | AB | 23 | 13 | 10 | 13/04/2022 |
| 4 | AB | 12 | 11 | 8 | 17/05/2022 |
| 5 | AB | 22 | 17 | 18 | 1/6/2022 |
| 6 | AB | 31 | 28 | 27 | 15/07/2022 |
| 7 | AB | 7 | 2 | 1 | 20/08/2022 |

Instead of the MAX filedate, use TODAY(). see this link for a description of the function and its caveats:

Hi, Anonymous ;
Try it.
L13W Requested Index = VAR L13R = CALCULATE(SUM([total requested(cases) ]),DATESINPERIOD('Table'[file date ], TODAY(),-91,DAY)) VAR L13A = CALCULATE(SUM([total sold(cases)]),DATESINPERIOD('Table'[file date ], TODAY(),-91,DAY)) return IFERROR(L13R/L13A,1.5)The final show:

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.
