This article explains how to set a rule to copy attachments from the parent ticket to the copied ticket using the app Create on Transition - Create Issues post function.
Instructions
You need to add a post-function in the workflow associated with the parent issue in the create transition.
- To create a post function:Log into Jira as an Administrator and click
> Issues. - Under the Workflows section, select the intended workflow, and click the Edit link.
- Select the transition to which you wish to add the post-function. Select the Post Function option as the following:
- Click the Add Post Function link. Select Create Issue from the available options.
- Once you add all the required fields to the post function, you see the post function like the following:
- Click Update and publish the workflow.
- Now create an Issue of any issue type. In this Example, an Issue is created of type Task.
- You will notice an issue is created from the parent issue and the attachment is also copied
The Copy Attachment post function works if the Parent issue and Child issue are from different Projects. Or else, there should be two workflows in the same project and the Parent issue should be in one project and the Child issue should be in another project.
