The event subscription rule function APIs provide standard rule functions that you can assign to event subscriptions. A rule function specifies the processing that Oracle Workflow performs when the subscription's triggering event occurs.

Oracle Workflow provides a standard Default_Rule function to perform basic subscription processing. The default rule function includes the following actions:

• Sending the event message to a workflow process, if specified in the subscription definition

• Sending the event message to an agent, if specified in the subscription definition

Oracle Workflow also provides some other standard rule functions that you can use. The Log, Error, Warning, and Success functions can be used for testing and debugging your application. Other standard rule functions provide specialized processing used in predefined Oracle Workflow event subscriptions or in special options you can choose to refine your subscription processing.

These rule function APIs are defined in a PL/SQL package called WF_RULE.

• Warning

• Success

• Workflow_Protocol

• Error_Rule

The WF_RULE package also provides a standard generate function that you can assign to events for demonstration and testing purposes. A generate function produces the complete event data from the event name, event key, and parameter list.

• Default_Generate

Additionally, Oracle Workflow provides a standard Java rule function called oracle.apps.fnd.wf.bes.WebServiceInvokerSubscription that is used in event subscriptions to invoke a Web service.
