To map subclasses of a selected class to the same class map and table
In the Class column, right-click on the class whose subclasses you want to include in the same class map and then select the Map Subclasses to this Class Map command from the popup menu that is displayed.
This command is disabled if the selected class does not have subclasses.
All subclasses of that class are then mapped to the same table. Each subclass is displayed in a separate row. The down arrow at the right of the icon indicates that the class is a subclass of the class whose icon has a green arrow that points to the left.
Changes to the table name, update mode columns, or excluded or output callback options apply to all rows mapped to the same table.
