Sub-task creation conditions and post-functions configuration

[Iro Karavasili]

Hello all,

I've modified a workflow so that a Sub-task is created when customer Bug is Resolved and Service Case ID not empty, with the following fields:

Summary: Dev Automation needed
Assignee: the developer of the parent Bug

I would like to find a way to check if a sub-task already exists prior to creating one with the same title.

The criteria is to not create a sub-task if another one with the same summary is found.

Any suggestions?

Kind regards,
Iro
