Hey Matthieu! Airtable formulas only have access to one row of data at a time. So a formula executing in one row has access to any column values it needs, but not any other rows. The exception is the functionality that linked records/lookups afford, but I don’t think that helps in this case.
The alternatives you’re left with are probably:
- filtering, sorting, or grouping your list by date ranges
- write a script to populate TEST whenever you click a button
- rig up a third party integration that automatically scours for updates to the base, and updates the TEST column as necessary
Best of luck!
Many thanks for your answer.
Doesn’t look easy for me
Do you know where I can find somebody who can help me on this point?
