We use jira product discovery to manage our high level product strategy, and two separate jira software projects to manage the delivery of this strategy. We link the ideas in the product discovery project A to issues in jira software projects B and C for the purposes of tracking idea delivery. We want to run a report from project B and C detailing the issues currently being worked on by the engineering team, but maintain a link back to the strategic view by including the idea in project A for which a given issue in B or C is a delivery task.
things i've already tried:
Parent field returns epic in B or C
Parent link doesn't seem to contain any data
report from project A on delivery status of issues in B or C doesn't give sufficient granularity; all that I can see is a progress bar without any information about the issues being worked on.
