When a process is added to a process as a sub-process, its steps become part of the main process. The steps and all information provided in or related to a sub-process step are handled the same way as any other step within the process.
For example, information provided in a sub-process step can be used in other steps or decisions as "previously entered field". When a step canceled, it behaves the same way as a main process step. When the ticket is closed, so is the sub-process.
