I want to check for each ticket in a given set of tickets, if a "linked issue"/"linked issues" was/were created before concerning ticket. Or stated otherwise, I want to know if the linked issue existed before the current issue.
Workflow
In our workflow issues are logged in several projects (e.g. project A,B,C). If further analysis or development is needed, a new issue is logged in project X. Once the analysis/development is done, the issue gets closed in project X and the linked issues in projects A,B or C are set to "ready for retest".
Thanks!
