Process models are used as the basis for running processes.

A workflow user must be set up in Customizing for Basis Components under Business Management ® SAP Business Workflow ® Maintain Standard Settings for SAP Business Workflow. This enables the program to be executed correctly.

1. The process starts with a selection program which determines the personnel numbers for processing. The selection program can either be started in the background or directly from the HR Process Workbench. It triggers a workflow event, starts the process, and transfers the process control to a function module, otherwise known as the Process Manager.
2. The Process Manager determines the next step, and starts the accompanying program in the background.
3. At the end of the program, control is given back to the Process Manager. The system checks the status of the process step and checks whether other steps follow. A container transfers the information from one process step to the subsequent step. The content of the container is always saved so that the information on the individual steps is never lost.
4. The next program is started with the information from the container and from the results tables for the preceding program.
