Note:

This option is available for Data type layer only.

Attribute(s) defining unique value combination

To prevent duplicate records in the database, write the name(s) of any attribute(s) to be used as a unique key. When a unique key is defined, it is not possible to store duplicate records for the respective attribute or attributes combination during data collection.

Example shows Shrub species attribute as a unique key. When attempting to store record with the same species, a warning message appears and a value before leaving an active record needs to be changed.
