Purpose
A process model is the basis on which a
process is executed.Prerequisites
You have set up a system administrator for the workflow by accessing Customizing for the SAP Web Application Server and choosing Business Management ® SAP Business Workflow ® Maintain Standard Settings. For more information on SAP Business Workflow, see the
reference documentation.
You have activated the workflow events triggered automatically by the HR Process Workbench during processing by accessing Customizing for Payroll and choosing Background Processing With HR Process Workbench ® Activate Type Linkages for Workflow Events.

The events in question are JOB_STARTED, JOB_ENDED, JOB_ABORTED, and STEP_ENDED. They control technical processing for a process model. For example, the JOB_STARTED event is triggered automatically when you start a process. The STEP_ENDED event is triggered when a process step is concluded.
These events are not identical to the workflow events that you can use for a
Process flow
Result
The process based on the process model is concluded. An overview of the status of individual process steps is displayed in the HR Process Workbench. Notification is sent to particular persons, depending on the definition of the individual process steps.
