Sequence flow from and to subprocesses

When a process folder reaches a subprocess object, all objects that do not have any incoming sequence flows are triggered. A process folder with the process number of the superior process folder is forwarded via these Start objects. Simulation of the subprocesses is terminated when all process folders with the same process number have left the subprocesses. When the last process folder leaves the subprocess, the outgoing sequence flow of the subprocess is activated. This means that one process folder with the process number of this process folder is forwarded to the next object via the sequence flow.
