Customized process flow bar
The process flow bar is the area at the top of the main process screen that shows the overall process involved for a particular application. At each stage of the process, a number of available actions can occur for each process state.
You can customize the process flow bar to extend the actions that can occur for any individual process state. You cannot customize the process flow stages.
If you wanted to add a new value to the "Investigation and Diagnosis" stage of an incident, you could add a new action to appear on the menus via configuration data in the system, and then add your own Active Link workflow that would be triggered based on the selected data.
