Show the Summary of the Parent ticket when viewing the Sub-task

[Marc Jason Mutuc]

My goal is to display the Summary of the Parent of a Sub-task. Appreciate the help! Thanks!

You can create a script field. Here is a code to get summary of parent issue

import com.atlassian.jira.issue.Issue

return issue.getParentObject().getSummary()
