Execution Class

 PREVIOUS NEXT

You can map a class to an execution class by specifying its execution class name. For example, you can map the business class RichCustomer to an execution class Customer.

You define the execution class in the Execution class name field of the BOM to XOM Mapping section of the BOM Editor.

When you execute, the execution class is used instead of the business class whenever needed. The BOM to XOM mechanism assumes that members of the business class are the same as the members of the execution class if they are not explicitly mapped, and uses them as described in the following table:
