Can I retrieve all parent and childs of an issue being in a project whatever projects they are in

[COLLIN, Laurent]

Good morning, I need to create a search query that will give me all issues in a given project but I would like in the result to see full hierarchy of the issue, parents and childs even if they are not in the same project. For example GPSL-23 epic is child of initiative CATALOGDEV-143 and has a story child of CDSP-45

Hi @COLLIN, Laurent 

Welcome to the community !!

If you are fine with a mktplace app, to get this data, you can try out our plugin and see the complete hierarchy for your cross project issues as well.

Agile Tools : Epic Tree, Links Tree, Time in Status & Worklogs

Disclaimer : I work for the vendor who built this app

Hello @COLLIN, Laurent 

Welcome to the community.

Jira does not natively support a function that will give you the full hierarchy of of issues.

Are you using Jira Cloud or Jira Server/Data Center?

There have been several posts on that topic in this community and the Jira Software Questions community. You might want to do a bit of searching to find those posts and see what other solutions have been proposed. There may be third party apps that you could use to get the information.

There have also been change requests opened with Atlassian on this topic, depending on the hosting type of Jira in use.

Regarding being able to see the hierarchy even if the related issues are in other projects, a prerequisite to that would be that you have the Browse Projects permission in those other projects. If you don't have that permission then you won't be able to see the related issues in the other projects.
