Overview of Object Interface Events and Extension Events

An object interface event is a type of object interface method that Siebel Engineering creates. A Siebel object includes a set of events that correspond to different points of execution during the lifetime of the object. An event acts as a placeholder in this Siebel object. It replies to a method that executes on the object.

Some object interface events allow you to associate custom code with a Siebel application. This code is available in Server Script or Browser Script. If the Siebel application starts the event, then Siebel CRM calls the custom code and the predefined Siebel code that is associated with the event.

You can use the following types of object interface events:

• Preoperation event. Occurs before the predefined Siebel operation runs. The PreDeleteRecord event is an example of a preoperation event. This event occurs before the DeleteRecord event occurs. To modify the behavior of a predefined Siebel application, you can use a preoperation event. For example, to perform custom validation on a record that Siebel CRM is about to delete, you can use the PreDeleteRecord event. If the validation fails, then you can instruct Siebel CRM to cancel the DeleteRecord operation.
• Postoperation event. Starts after Siebel CRM finishes executing the preoperation event. The DeleteRecord event is an example of a postoperation event. For example, Siebel CRM starts the DeleteRecord event after it finishes executing the PreDeleteRecord event. The postoperation event handler is rarely scripted, but you can use it for some postoperation events, such as posting a notice to a log if the event completes successfully.
