find the earliest date based on two columns
I am trying to take the earliest date based on criteria from two other columns. I need to track systems as they complete control testing of subcontrols to satisfy the base control. See example below:
| System | Controls | Subcontrol | Date |
| link | ac-1 | ac-1.2 | 1/15/2020 |
| link | ac-1 | ac-1.4 | 5/5/2021 |
| link | ac-1 | ac-1.9 | 5/6/2021 |
| haltech | sc-2 | sc-2.3 | 2/20/2023 |
| haltech | sc-2 | sc-2.4 | 2/20/2023 |
| haltech | sc-2 | sc-2.7 | 4/2/2023 |
This is what I am trying to achieve:
| System | Controls | Subcontrol | Date | Earliest test date |
| link | ac-1 | ac-1.2 | 1/15/2020 | 1/15/2020 |
| link | ac-1 | ac-1.4 | 5/5/2021 | 1/15/2020 |
| link | ac-1 | ac-1.9 | 5/6/2021 | 1/15/2020 |
| haltech | sc-2 | sc-2.3 | 2/20/2023 | 2/20/2023 |
| haltech | sc-2 | sc-2.4 | 2/20/2023 | 2/20/2023 |
| haltech | sc-2 | sc-2.7 | 4/2/2023 | 2/20/2023 |

Hi,
This calculated column formula works
=CALCULATE(MIN(Table1[Date]),FILTER(Table1,Table1[System]=EARLIER(Table1[System])&&Table1[Controls]=EARLIER(Table1[Controls])))Hope this helps.
