Dynamic task - back push

chandra1 — Tue, 08 Apr 2014 13:50:25 GMT

We have a scenario like this A –> B –> C –>DAfter completing C the user decided to go back to B which is not defined in the process. Is there a way to achieve this?

Hi Chandra,

Try to use exclusive gateway in process design.

Thanks for the suggestion.

Exclusive Gate way is a good if we predefined the conditions.

But in my case, go to previous step from C–>B or C—>A is not defined in process. Adhoc basis user decided to push the task from C–>B or C–>A programmatically.

Hi Chandra.

I think exclusive gateway could be applied in this case too.
let's follow this audit trail

A - complete task
B - complete task
C - set variable whereToGo to "A" and complete task
X - exclusive gateway decision based on the whereToGo variable. Outgoing link to the node A is taken.
A - complete task
….
