Sub-Processes

Sub-processes are simply processes that are started by a task in another process. And sub-processes can be many levels deep, that is, a task in one process can start another process, which can contain a task that starts another process, and so on.

From the process instance list, you cannot distinguish which process instances are from a main process or from a sub-process.

You can, however, see when a task starts a sub-process using the Event Viewer. If an event in the Event Viewer has a character to the left of the event, it means it is a sub-process start event:

Clicking on the character expands the list to include the events related to the sub-process that was started.
