Oracle Workflow provides several predefined events for significant occurrences within the Business Event System. See: Predefined Workflow Events
When you define an event in the Event Manager, you must assign it a unique internal name, which is case-sensitive. The suggested format for these internal names is a compound structure of identifiers separated by periods (.) as follows:
<company>.<family>.<product>.<component>.<object>.<event>
This format allows you to organize the events you define into a classification hierarchy.
The application where the event occurs can include the event data when raising the event to the Event Manager. If the application will not provide the event data, you should specify a Generate function for the event that can produce the complete event data from the event name, event key, and an optional parameter list. The Generate function must follow a standard API. See: Raise, Oracle Workflow API Reference and Standard API for an Event Data Generate Function.
The Event Manager checks each subscription before executing it to determine whether the subscription requires the event data. If the event data is required but is not already provided, the Event Manager calls the Generate function for the event to produce the event data. If the event data is required but no Generate function is defined for the event, Oracle Workflow creates a default set of event data using the event name and event key.
Note: If the Generate function is costly, and you want to return control to the calling application more quickly after raising the event, you can defer all the subscriptions that require the complete event data. Then the Event Manager will not run the Generate function until those subscriptions are executed at a later time. See: Deferred Subscription Processing.
You can associate an event with the program or application to which it belongs by setting the program name and brief identifier as the owner name and owner tag for the event. For instance, in the example of the purchase order event, the owner would be the purchasing application. The program can then use this identifying information to locate the events that it owns.
Your Oracle Applications installation may include seeded events owned by Oracle Applications products that you have not licensed. For such events, the Update Event page displays a notice that the event is not licensed. Oracle Workflow will not execute any subscriptions to these events. Additionally, Oracle Workflow will not execute any subscriptions owned by products that you have not licensed, even if the triggering events for those subscriptions are licensed.
You can use the License Manager AD utility to review which products you currently have licensed. To ensure that the license status of the seeded events and subscriptions in the Business Event System is updated according to the status of the products you currently have licensed, you can run the Synchronize Product License and Workflow BES License concurrent program. See: License Manager, Oracle Applications AD Utilies Reference Guide and Synchronizing License Statuses, Oracle Workflow Administrator's Guide.
Note: Any events that you define with a customization level of User are always treated as being licensed.
Note: Event groups cannot be used to raise events. You must raise each event individually.
