How to calculate a value from one column based on another column's maximum value
I have table as shown below. For each Reference, there may be multiple rows at different dates. I want to be able to create a calculated column that will evaluate, for each Reference, the value of the Count field where the Date is the maximum for that Reference (ie not just the maximum date in the table as a whole) Is this possible?
| Reference | Count | Date |
| A | 106 | 01/10/2020 |
| A | 81 | 01/10/2021 |
| B | 3 | 01/11/2022 |
| B | 17 | 01/11/2020 |
| B | 18 | 01/11/2023 |
| B | 15 | 01/11/2021 |
| C | 19 | 10/07/2023 |
| C | 19 | 01/11/2022 |
| D | 51 | 01/06/2021 |
| D | 58 | 01/06/2023 |
| E | 2 | 01/04/2021 |
| E | 2 | 01/04/2022 |
| E | 23 | 01/07/2021 |
What I am aiming for is:
| Reference | Result |
| A | 81 |
| B | 18 |
| C | 19 |
| D | 58 |
| E | 2 |
Many thanks for any help for this !
Hi MatthewUK ,
You can achieve this by using:-
Result =
VAR MaxDate = CALCULATE(MAX('YourTable'[Date]), ALLEXCEPT('YourTable', 'YourTable'[Reference]))
RETURN
CALCULATE(MAX('YourTable'[Count]), 'YourTable'[Date] = MaxDate)Hope this will help you.
Thank you
