If the Is Updated checkbox is selected, the field is updated using a database manipulation language (DML) operation, such as insert or update. For more information, see Understanding Dependencies.
If the Is Updated checkbox is not selected, the field is only referenced within the operational scope. For example, it may be included as part of a select statement.
If the External ID checkbox is selected, the field acts as an External ID. An external ID field contains unique record identifiers from a system outside of Salesforce. You can use the sidebar search to find external ID values, and you can use the field in the Lightning Platform API. When using the Data Import Wizard for custom objects and solutions, you can use this field to prevent duplicates.
