Subprocesses help to encapsulate functionality to deal with complexity, enable r

Hi,
It depends on your following use cases-

1. In case you want your variable value to be passed to the parent process only when it's completed , then you can pass your variable as an output in the subprocess node in parent process model.

2. If your use case says the value of the process variable should be there in the parent process as soon as variable is updated in the sub process , then pass it as by reference.
NEVER PASS A CDT AS PASS BY REFERENCE.

3. If you want to set the value of the variable in the parent process which is not available in the sub process, you can use Set External Activity smart service.
