Hi,
I am using initiatives for my projects and I have child Epics that represent key milestones in my initiative. I'm using the target end date to present when those Epic milestones should be completed.
I would like to create a structure formula column that shows the initiative's next milestone date by pulling from my open child Epic's min target end date. The next target date would be the min target end date of any still open Epic. (ie Closed epics mean the milestone has already passed/been completed. Open epics would be upcoming milestones and the min function would pull the upcoming nearest milestone)
I believe the solution may be something similar to this answer.
