What I want to accomplish is an overview of PBIs that are not marked as done, but all the tasks of them are done (so that the PBI should be marked as done as well).
This is similar to this item: Query VSTS for all PBI's with no open tasks, except the answer is incorrect (because it does not check if all items are done, it only returns the items that are done).
This does return all PBIs who's tasks are marked done, but also PBIs that don't have tasks and only a parent.
Is it even possible to make such a query?
Thanks in advance.
