Copy subtask summary to custom field in parent issue

[Goli, Raja]

I would like to copy one of the subtask summary to a custom field in the parent issue.

Example Subtask Summaries:

Subtask1 Summary - STask123 Testing

Subtask2 Summary - STask456 Automation

Subtask3 Summary - STask789 Result

When the story status change to "Done", I want to copy the subtask summary "STask789 Result" to custom field in parent issue.

Jira Automation rule, I was able to lookup for a subtask which contains summary as "STask789" and created a custom variable to save the summary. Since I created the custom variable inside the FOR look I am not able to access outside of it. How can I achieve it?

I followed the Atlassian document and able to get the summary of the subtask using below smart variable.

Hope it will help

{{#issue.subtasks}} {{summary.substringBetween("Subtask3 Summary","-")}} {{/}}
