Can I copy a field value from sub-task to the parent issue


I am looking for a method to update a parent issue custom field with data from a sub-task when I transition a sub-task. (perhaps some post-function?)

Each of our issues will have one sub-task that will be assigned to a different user from the owner of the parent issue.

Part of our workflow requires the owner of the sub-task to input some text into a custom field. When the sub-task is closed I would like to copy that text to a custom field on the parent issue.

(for reporting purposes - we only look at the parent issue, but want to see this text update captured on the sub-task)

I hope this makes sense and any suggestions are welcomed

Hi James,

The JIRA Misc Workflow Extensions plugin has the post function you need :

Best regards,


Thanks Peter. No way of doing this without adding a paid-for addon?

These are all paid extensions. Are there any plans to add a post-build step to copy a field value to parent?

There's now a very easy to configure way to keep fields for parents and sub-tasks in sync using Automation for JIRA!

You can easily modify related issues (such as parents, stories, sub-tasks, epics, linked issues and even JQL) using our related issues action and condition:


(this example updates the description, in a sub-task when the parent changes, but you could reverse this too so a sub-task update, updates the parent)

For more details see

Another option is the newest version of the plugin Workflow Essentials for JIRA.

It contains a post function to copy values from sub-task to parent (and vice versa if you need that).

Run a script as postfunction on the tansition to Done on the subtask. 


def parentKey = issue.fields.parent.key
def issueKey = issue.key
def tradeTermsKey

def parent = get("/rest/api/2/issue/" + parentKey)
.header('Content-Type', 'application/json')

def parentUpdate = put('/rest/api/2/issue/' + parentKey)
.header('Content-type', 'application/json')
fields: [
customfield_11901: issue.fields.customfield_11901, // Customer updated from number field to text field
customfield_11900: issue.fields.customfield_11900 // Vendor updated from number field to text field
