This post-function is obsolete. While you may continue using this post function, which will not be removed from JMWE, we recommend you use the more powerful Copy issue fields instead for new automations.

Troubleshooting this post-function configuration: In case the post-function does not work as expected these are the things to look out for
JMWE shows an error message on the issue view if any error occurs during the execution of the post-function. This message is displayed only if the current user is a Jira administrator.
When you add this post-function to a transition and trigger the transition, the add-on copies the value(s) of the selected field to the same/different field of the issue's parent issue.
Destination field: Allows copying to a different field than the source field. For example, automatically add the Reporter of the parent Epic to the Watchers of a User Story. Note that if the source field is read-only, you cannot select Same as source field in this option.
Copy only if not set: Copies the value(s) of the selected field into the same/different field of the issue's parent issue, only when the field is empty on the parent issue.
Create missing value(s): Allows creating any missing Component/s or Version/s while setting or copying a field that expects Versions or Components. Note this is applicable for version and component fields.
Ignore empty value: Will not set (clear) the selected field of the parent issue, if the value from the current issue is empty or null.
Add subtask's value(s) to the parent issue: Appends the value(s) of the selected field to the same/different field of the issue's parent issue. This is applicable only to multi-valued fields.
Send notifications: Jira sends notifications for the change in the selected field value on the parent issue. You can control the default value of the "Send notifications" option in the Configuration page under JMWE administration. Click here for more information.
A typical workflow use case for this post-function is to copy a field value to the parent issue from the subtask during a transition. Consider a use case where you want to copy the labels from each sub-task to its parent when the sub-task is closed. To configure this:
Add the Copy field value to linked issues post-function to the Create transition of the Sub-task workflow.
Select Labels in Source Field.
Select Same as source field in the Destination field.
Check the Add subtask's value(s) to parent issue option.
