In scheduling, the system calculates the start and finish dates
of orders or of operations within an order.
Scheduling is carried out in
MRP: The in-house production times and the delivery times
specified in the material master record are taken into
account.
Capacity planning: Scheduling is carried out via the task list
(such as, routing or inspection plan). A distinction is made
between lead time scheduling, in which capacity loads are not taken
into account, and capacity scheduling (finite scheduling), in which
capacity loads are taken into account.
Networks: Scheduling calculates the earliest and latest dates
for the execution of the activities as well as the capacity
requirements and the floats.
The following scheduling types exist:
Forward scheduling: scheduling starting from the start
date
Backward scheduling: scheduling starting from the finish
date
Scheduling to current date: scheduling starting from the
current date
"Today" scheduling: a scheduling type which can be used to
reschedule an order if the start date is in the past.
