Copy custom field values into another custom field

Fariz Aliverdiyev

Good day everyone. 

There is a sub-task workflow, which consists of two statuses: Review and Approved. When moving to Approved from Review user should fill Decision field on a transition screen. For example, number of sub-tasks is 7. All of them have their Decision field values.

So, the question is how can I copy all these Decision field's values from different subtasks into a single custom field, let's say, Overall Decision, in parent task? 

Thank you in advance.

Hi @Marco Brundel , @Tinker Fadoua , 

Thank you for answers. There is a Scriptrunner plugin in the system, but no Automation for Jira Pro version.  

I recreated the rule @Marco Brundel shared, but on Automation Rules (JWT) plugin:

It works, but there is a problem. When the descision of the first sub-task "marketing approve' is edited to "marketing approve 1", the rule doesn't edit it on the parent task, it just adds it as a new decision. Example screenshot:

Is there is a way to avoid it? 

Thank you in advance.
