If I have an iteration (sprint from JIRA agile scrum board) scheduled (e.g. over two weeks) for all team member and I add something in that time frame (custom entry or story in time line or classic view) for all team members, commitment for the iteration is not reduced but everybody is simply over committed..
When I do the same but only add something to one team member, it works and commitment for the iteration is reduced at that specific date and I also see the entry as blocking in backlog mode.
How can I do something like plan a sprint / iteration in tempo planer and then add an event to reduce the available time for the whole team for the sprint / iteration?
