Back to Previous Task

[mackhong]

Could I know if possible to back to previous task after the task is set complete?

eg. my flow are  registration -> channel -> subscription.
All of three tasks are UserTask. When I set subscription task is complete, how can i back to previous channel task ?
Which API can I use?

many thanks

You need to explicitly model the flow back to the user task. It would be against BPMN to allow going back to every step.
