You can configure a custom field, that captures the session data that you want for later use in reports, Watchpoints, and other system entities.
Note
When you create an object custom field, you can create equivalent page and session custom fields
automatically. Similarly, when you create a page custom field, you can automatically create an
equivalent session custom field. These automatically created custom fields are known as inherited custom fields. You can create them only when you create the original custom field.
An inherited custom field uses the same grammar name identifier as its parent and shares other settings. To change a custom field setting but not affect the field created by inheritance, you must first break the connection by changing the grammar name of either the inherited field or the parent field.
