After adding a subflow activity, you must specify the subprocess it invokes.
By default the Creation Activity run asynchronously and the subprocess does not return arguments to the parent process. If you need to wait for the subprocess to finish or need to retrieve its output arguments, you can add a Termination Wait activity. For more information about Termination Wait activities, see Termination Wait Activity.
You can add Subflow activities in user-defined or automatic role lanes.
You must connect a Process Creation activity to the process flow using an inbound and an outbound transition. An error appears in the Problems View if the inbound or outbound transitions are missing.
You may need to define an argument mapping when the subprocess requires input arguments.
