How to Specify Escalation Rules

This option allows a custom escalation rule to be plugged in for a particular workflow. For example, to assign the task to a current user's department manager on task expiration, you can write a custom task escalation function, register it with the workflow service, and use that function in task definitions.

The default escalation rule is to assign a task to the manager of the current user. To add a new escalation rule, follow these steps.

To specify escalation rules:

Implement the following interface:
```
oracle.bpel.services.workflow.assignment.dynamic.IDynamicTaskEscalationFunction
```
This implementation must be available in the class path for the server.
Log in to Oracle Enterprise Manager Fusion Middleware Control.
Expand the SOA folder in the navigator.
Right-click soa-infra, and select SOA Administration > Workflow Config > Task tab.

The Workflow Task Service Properties page appears.
Add a new function. For example:
- Function name: DepartmentSupervisor
- Classpath: oracle.bpel.services.workflow.assignment.dynamic.patterns.DepartmentSupervisor
- Function parameter name
- Function parameter value
In the Custom Escalation Java Class field of the Deadlines section, enter the function name as defined in the Workflow Task Service Properties page for the escalation rule.
