Does anyone know if there is a filter (query) to filter all child issues within a Initiative and then be able to pull it to Portfolio? I would like to see the Initiatives in Portfolio along with their child issues. I haven't been able to get this to work. Thank you!
Are you on Server?
This is possible via the instructions from Roi's comment on this thread:
If you're using Cloud, then it's not possible natively but you may be able to do so via Scriptrunner.
