Canceling all instances of a sub process

allenk over 7 years ago

I have a process model, in which i launch a sub process with x number of instances, based on another data item.
In the parent process there is a user task (related action) in which a manager can move the process along without waiting on the sub process to have been completed
On the sub process node I added an exception to go to an End point (not a terminate, as the process still needs to finish), if the status of the process was changed by the manager above.
The issue i am having is that if there are 2 + instances of the sub process which haven't yet been completed only the first one goes to the end point, the second, third, ext, does not, they stay as they were. Is there a way for me to cancel all instances of the sub process rather than just the first instance.

Any thoughts.

Would it be reasonable for the related action to message the all the subprocesses and tell them to terminate? forum.appian.com/.../Process_to_Process_Message_Type.html That way, you ensure that all the subs behave as you expect them to, and you don't have any lingering instances.

How did you set up your exception in the subprocess? By having the subprocess waiting on a rule event with a boolean pv and setting up my parent process to use a send message node to update that pv in the subprocess i was able to successfully ended all instances of the subprocess.

Thanks you two,

the exception was setup on the Sub-Process node itself within the main process. I was hoping to not have to modify the sub process itself, but it seems the process to process message may be the way to go.
