Create subtask per participant Jira or Script Runner

Gova Q

Hi I am new on Jira and I have been assigned to a project where I have a main Issue type let's call it: PARENT

And then once the PARENT gets the status: IN PROGRESS it automatically create a subtask per Participant and assign this one to each one and also takes the summary from this PARENT issue and then set it as the summary of each Subtask.

I know that action should be shot in a transition. However, I have tried to figure it out how can I accomplish this but it's hard for me to catch something.

I know my work has an app called ScriptRunner which for what I have been looking for it's a good one that could help me out with this, but I do not have fully knowledge about it.

Thank you in advance for all your help, time and information that can help me to reach this goal.

Best Regards.

Dear Gova,

thank you for your question. You have a quite interesting implementation there!  

Scriptrunner could indeed help you to achieve what you are looking for. 

Take a look into this post: https://community.atlassian.com/t5/Jira-questions/Script-Runner-create-sub-task-post-function-set-component-and/qaq-p/89392

Moreover, you could use the post-function on the transition before "in progress" to trigger the action of creating a sub-task. Remember to put your post-function AFTER the post-function called "re-index" issues, otherwise you might run into problems. 

Let us know if the article helps or if you have more questions.
Cheers
