Programmatically start subprocess on any step of Execution?

[sergeolyva]

Hi all,
my problem is that I need to have a possibility to cancel further execution of a process,  and also execute additional steps on cancellation,
here is the example:

problem is that I don't know how to start cancellation process programmatically. Is it possible?
Thanks in advance,

Hi Serge.

I would say, the easiest way could be to use boundary events. E.g.
