Table Of Contents
Basically a subworkflow is an ordinary workflow started by the task
<ForkSubprocess> within another workflow. The subworkflow may be passed
parameters via the subelements of the <Parameters> element.
A subworkflow is always started as a separate process, while the main process continues. There are two different ways in which a subworkflow may be started:
Synchronously via
<ForkSubprocess detached="false">If the main workflow is suspended, resumed or aborted, the subworkflow is suspended, resumed or aborted, too, but it may finish without affecting the subworkflow.
The main workflow may wait for the subprocess to complete or to be aborted via the
<JoinSubprocess>task. Note, that it is not possible to loop (see Section Section 4.1.5, “Flow Control”) a <ForkSubprocess> and join all subprocesses afterwards. Use recursion in this case so that each subworkflow starts exactly one subworkflow.Asynchronously via
<ForkSubprocess detached="true">or simply<ForkSubprocess>If the main workflow stops, the subworkflow is not affected. Since they are not connected, there is no possibility for the main workflow to wait for the subworkflow to finish.
