Customizing the Outcome of an Object Interface Event
A preoperation event handler exists for every Siebel operation event handler. You typically place a script in the preoperation event. The PreInvokeMethod event results in the most important outcome. In a PreInvokeMethod event, you can call an object interface method that substitutes the predefined Siebel code.
