I want to catch Cancel end event(Reject) from Subprocess using Boundary cancel event but it always throws "No execution found for sub process of boundary cancel event" error. Can someone suggest me how to fix it

Hey @manhld,

Why are you using cancel events for this instead of error?

The Cancel events work together with Compensation. This is meant to work cross transactions. I have not tried your example, but I believe that the problem you are seeing is there because you try to do this within the same transaction.

Can you perhaps share the BPMN XML so we can try it out?

Cheers,
Filip

Thanks for your reply @filiphr ,
As the figure shows, in the sub-process I want to catch two separate events, one for the update request event, one for the approval event corresponding to each gateway. I want to catch these events to navigate using the corresponding boundary events. Seems a bit difficult for a newbie like me to approach. You can edit on my bpmn file.
