Update Subtask Assignee on Master Task Assignee Change

[Beau Butner]

I want to have JIRA automatically set the assignee on each Subtask if the Master Task assignee changes. So say you create an Issue with 4 Subtasks, yet it is not assigned to anyone yet and is for grabs. Someone comes along and assigns the Master Task to their self. They then have to go in and manually update each Subtask to have the assignee as them. I'm looking to automate that process.

I've got ScriptRunner, however I'm very inexperienced with how exactly to use it. Any suggestings?

 You can customize the Built-in Script of the documentation below to get what you are needing with ScriptRunner:

Subtask Default Fields

However, if you are not very familiar with Groovy Scripting, I recommend you to use Plugin Automation for JIRA (300 free executions per month) and simply configure the following rule in your project:

Please, let me know if this information helps you.

This worked beautifully, and is a lot easier to use than ScriptRunner! I've actually just uninstalled ScriptRunner and installed this instead, thank you very much for the share!

You are welcome, Beau!

I'm glad to know that I was able to provide a better option for your business case.

Have a nice day!
