Copy summary from linked issue(parent issue) to custom field of child issue when child Issue created

Question

Hello Team,

I am trying to copy "summary" from linked issue(parent issue) to custom field of child issue when child Issue created through Big Picture.

here is my Listener at created event.

import com.atlassian.jira.component.ComponentAccessor

def issueManager = ComponentAccessor.issueManagerdef customFieldManager = ComponentAccessor.customFieldManagerdef issueLinkManager = ComponentAccessor.issueLinkManager
def issue = event.issue
def currentIssue = issueManager.getIssueObject(issue) // Replace with your issue keydef customField = customFieldManager.getCustomFieldObjectsByName("Related Project Task") // Replace with your custom field name
def linkedIssues = ComponentAccessor.getIssueLinkManager().getInwardLinks(issue.getId()).collect { it.sourceObject }def systemFieldName = "summary"def field = fieldManager.getField(systemFieldName)
linkedIssues.each { linkedIssue ->    def fieldValue = linkedIssue.getFieldValue(field)          if (fieldValue) {        currentIssue.setCustomFieldValue(customField, fieldValue)        issueManager.updateIssue(ComponentAccessor.jiraAuthenticationContext.getloggedInUser, currentIssue, EventDispatchOption.DO_NOT_DISPATCH, false)    }}Thanks,Venkatesh

Hi @Venkatesh Pettem - I suggest spending some time playing with the rules and the documentation and templates at https://www.atlassian.com/software/jira/features/automation . In the meantime can you mark my answer correct?  Your last question is really just about details - copying different fields or editing the logic to include a linking event is very similar to the example I gave. You can do pretty much anything with automation!

your mentioned rule will copy Request type (custom field) value of Parent Issue to Request type of newly created Issue.

How do I copy(map) summary of existing issue to the newly created issue (which is then linked as "Child Of" existing Issue) custom field (single text) value?

Please Advise.

Thanks,

Venkatesh

You're getting there! Your rule is firing when an issue is *linked* to a parent, which is a bit different than what you said before (when a child is created). Here's a working rule for copying a custom field to a newly created child - you can edit it or have multiple rules if you want to handle both "I created a new child" AND "I linked an existing issue to a new parent".

Here's my rule:

Note that there is a "Multiple Issue Events" trigger that could handle both Create/Link events, but I think those are harder to read.
