Rollup: attributing value to multiple sources

[Jeffrey_Brandt]

Hi,

I have a conditional rollup where I am doing an Arrayunique of events that occurred in a specific Academic Year.

If the array is empty (meaning, the event was not scheduled in said year), then I want the rollup field to say “Not Scheduled”. Is that possible? I currently am doing this by using the Rollup as a helper column, but would love it if I can do this all in one.

Adjust your Rollup’s aggregation formula to be

IF(values, ARRAYUNIQUE(values), "Not Scheduled")
