As a backlog planner, I would like to have validation logic on fields to let me know if an entry is outside of a parent's or children's parameters so that I can have a conversation with the owner to make changes.
For example, if I schedule a requirement outside of the end date of a related initiative, I would like to have a warning so that I know to have a conversation with the initiative owner about end dates.
Another example is if I assign a requirement to a team member who is not a member of a team whose capacity is included with the parent feature, I would like to be warned so that I can have a conversation with the feature owner.
