You must "level" in order to properly plan demands with respect to capacity. You can solve this challenge through automatically converting to a mixed integer and linear optimization problem in an SAP ERP / SAP S/4HANA Model.
In this model, parameters control the weighting of contrasting goals such as meeting deadlines and dividing equally among assembly groups.
As a result of optimization, you obtain a maximal production workload. Some orders are produced too early, others produced too late. There are a great deal of orders that cannot be planned. Now the planner’s actual task begins. S/he can change capacities (red horizontal line) in consultation with production, interchange orders by the day within capacity limits and with stock, change order intervals, etc.
The user packs an order with the mouse (moving via "Drag & Drop") on 10/06 and sees the marked time interval in which this order may be permissibly planned above as a large light-green rectangle. It is easy to recognize that the optimizer planned the order outside of the interval (too late). The “penalty” for missing a customer deadline was not high enough for the optimization program. Hence, the customer deadline can no longer be met. An on-track plan can be forced for critical orders through manual rearrangement with increased leveling costs.
