The data of the Component Field can be stored in a database, or it can be exchanged with other components via entity or occurrence parameters. |

The Component Field cannot be externalized. |
Description
In most cases, the value of Is External is determined by the Database Behavior property of its parent
entity. By default, if an entity's Database Behavior property is T
, each of its fields has its Is External property set to T
, and vice versa.
However, if you are defining a component that
needs to exchange information by means of entity or occurrence parameters, the fields to be
included in the data exchange must have Is External set to T
,
even if the parent entity is not a database entity.
