Is there a way to configure a field to not accept adding new records similar to the ones already existing in it. Simply, preventing that field from creating repeated or duplicated values?

Any help is appreciated

Best Regards,

Try creating an "unique" index on top of the field you want to restrict.

Hope this helps
