No duplicate inventory number

[ayclau]

I want to catalog a physical library and want to add a column for inventory number. The default ID column doesn’t work for me because half of the books already have an identifying number.

I created an inventory number custom column, can I make it so it doesn’t allow repeating numbers?

You could write an action chain to check for duplicates. Or you could store the IDs and manually scan for duplicates.
