Hi ,
We have a scenario were we have shortage(demands on 06.07.2016) within the planning time fence (5 days) and when we run PP heuristics we can see that the planned orders start within the PTF and are available on 11.07.2016 with PP firmed indicator (creating an overload).
In DS board there is a fixing interval of 2 days (until 08.07.2016) and there are sufficient slots available to schedule the orders after the 8th. Now when we run backward re-scheduling with earliest date in DS strategy the orders are re-scheduled only from 10.06.2016 leaving out the slot between the 8th and 9th empty, if we run the rescheduling with forward and earliest date in DS strategy the orders are scheduled right after 08.07.2016, utilizing all the slots.
We expect that when we run backward scheduling the orders should utilize all the slots after the fixing interval as the demands lie in the past.
Please help understanding the behavior.
Thanks,
Rajan,
