Jira Automation: create a subtask just once

[Jack Garrod]

Hi, 

I have a  transition from status B > C in which a sub-task is created via Jira Automation. however, after C it can transition back to A and then go back through the B > C transition. 

I want it to not create a second sub-task when transitioning B > C for the second time. 

Is this the correct setup? basically need Jira to recognise that a 'Check-List' subtask has already been created and not do it again. 

thanks

consider adding a label or a comment to the issue when it moves from B>C the first time. couple this with an extra condition, e.g. label != "already-happened".

Thank you, Ive actually found an alternative using the 'if no subtask match' and then it only makes a subtask if there isn't one there already.

yep. I didn't suggest that as I was unsure if you would ever have more than one sub-task. Generally speaking, when using sub-tasks you have more than one. Sort of like a bulleted list.
