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.
