Scheduling 

Use

In order processing, the scheduling function calculates the production dates and capacity requirements for all operations within a process order.

The scheduling process starts with the basic order dates (basic start and basic finish). The system either takes the basic order dates from the planned order, or you enter them manually on the header screen of the process order.

A process order is always scheduled automatically when it is created. In Customizing, you can specify whether you also want the order to be automatically rescheduled before saving whenever you make changes that are relevant to scheduling.
