We run a nightly Planning Optimization batch for the Default plan, but it does not remove all unfirmed orders. We have planned orders left over from months ago. It isn't a one time thing. I have done manual deletes, but eventually the problem builds again. I can no longer find a Delete Plan option or a Regeneration option in the Master Planning parameters.
How can I ensure that old planned orders don't remain in the system? If I run a manual recalculation, these orders are removed, so I know that they are no longer viable.
