I want to use the DATEADD() formula on only the oldest created value (date) in a Lookup column that stores multiple values (a 1-to-many relationship is needed). I can’t seem to figure out a way to design the base or write a formula that does this. Any ideas?
When I last tried a formula like this in a rollup field, it did not work. I had to put MIN(values) in the rollup field, and then do the DATEADD in a separate formula field. When I contacted support about the issue, support confirmed that it was necessary to use a separate formula field. I have found workarounds that involve using DATETIME_PARSE in the rollup field, but I don’t like it.
