Perhaps it's due to being Monday morning, but during a review of my sechduling options, I decided to review the "Dependency Scheduling" section closely.
I can choose to either Rank a dependent item below a required item, or alternatively, Rank a required item above a dependent item.....
So, insofar as these two seem to be exactly the same option, I checked the specific documentation at https://confluence.atlassian.com/jiraportfolioserver/dependencies-schedule-844237026.html.
hmmm. Not enlightening at all, and clearly needs to be re-written --
Solved! Go to Solution.
Thanks Steven. It would be nice to see your explanation added to or replacing the one provided by Atlassian.
