A special window is used to view and edit lookup records. To open this page, select a lookup in the list and click the [Open content] button.
Most system lookups are standard and contain only the [Name] and [Description] fields. Certain custom lookups have record edit pages.
You can deactivate lookup values to prevent the users from selecting these values in the future (). Deactivated values will not be available for selection in the corresponding lookup fields. All existing records where an inactive lookup value had been previously set will remain unchanged. Lookup record deactivation is disabled by default. You can enable it for specific objects in the [Configuration] section. More information about enabling lookup record deactivation can be found in the “ ” article of the Development guide.
