This is the documentation of JSU for Jira Cloud. If you are using JSU on Jira Server or on Jira Data Center, you can find the documentation here.
This post function will create a new issue. The new issue will be linked to the origin issue (the one, which triggered the 'Create a Linked Issue' post function).
Any number of fields can be copied to the new issue and within the origin issue.
See the Testing and Fixing Bugs use case for an example how several of our customers are using this post function. The video on that page shows you the following sample configuration in action.
Here you must configure some always mandatory fields for an issue. These are some real basic field of Jira. Be aware that your Jira configuration might have additional required fields (you should set them all by Copy Field Section) .
Additionally the summary will always be copied from the origin issue to the new issue. The reporter of the new issue will always be set to the user who triggered the current transition (and thus this post function). However you might overwrite them again later with Copy from the Origin Issue to the New Issue
Target Project can be set to:
A new issue will be created in this same project
A new issue will be created in the selected project.
Since JSU Cloud 1.1.0 The Create a Linked Issue post function allows you the create new issues, which are connected not only with an issue link, but instead also in a parent / sub-task, as well as epic / issue in epic relation.
See Releated Issues for more explanations on this topic (especially for creating sub-tasks).
Be aware, that the issue type you configure here must be available in the target project.
See the Use Case Testing and Fixing Bugs for a nice example, how several of our customers use it. The video on that page shows you the following sample configuration in action.
