Copy Field Value from Parent Issue to Sub-task Upon Creation

You can now vote for scripts to help people know if they're useful or not. Login or create an account to vote!

Overview

Copy any field value from a parent issue to a newly created sub-task.

Example

I have a custom field which dictates which components of work are needed. This information is the same for both parent issues and sub-tasks. This script means I don't need to enter these manually each time.

Good to Know

Implement this as the first post function on the Create step of a workflow.
fieldNameToCopy: Is the field name of the value to be copied.
