Is there a way to set up a lookup field without duplicates? I asked this here and I just noticed that the response didn’t fully solve the issue: The rollup formula ARRAYUNIQUE(values) still includes duplicates.



I’m not 100% sure if this will work, but you may want to try this formula to see if it works for you:


ARRAYUNIQUE(ARRAYFLATTEN(values))


Hmm this doesn’t do the trick. Any other suggestions?

Add a formula field containing ARRAYUNIQUE({Purpose (from Interventions}). This should work.


Read this discussion. May be this can help you here https://community.airtable.com/t/how-can-i-make-a-lookup-field-show-only-unique-results-uk49s. If yes then please mentioned me here.
