Define Scheduling Parameters for Production Orders (SAP Library

Define Scheduling Parameters for Production Orders

In this step you define for each plant, order type and production scheduler the parameters for scheduling production orders. This comprises maintaining

scheduling levels (detailed, production-rate and rough-cut scheduling)

date adjustment when dates are exceeded

date control for detailed scheduling

reduction

The parameters are described in what follows in details:

In detailed-, production-rate and rough-cut scheduling you definefor every scheduling level

how production dates are to be calculated

whether capacity requirements are generated

which routing is the basis for scheduling

If a production version exists in the material master then the routing is selected using this version. If no version exists for a scheduling level then a routing is selected according to the selection ID that you have given for the scheduling level.

In date adjustment you specify whether and how the basic dates are adjusted to the production dates (for example, when deadlines are exceeded) and how dates for dependent requirements are to lie.

In Scheduling control for detailed scheduling you specify the control parameters for detailed scheduling, among other things the

scheduling type

Here you specify in which direction scheduling is to be carried out and whether it is to be carried out to an exact time. Among other things you can specify that a scheduling run only be used to generate capacity requirements.

Start date in the past

Here you specify how many days an order may lie in the past before today scheduling is triggered.

Calculate dates automatically

Here you specify whether scheduling is carried out automatically on saving.

Display log automatically

Here you specify whether the log is displayed automatically on scheduling.

Required date of material

Here you specify where the required date of a component should be with respect to an operation.

Schedule exact to the break

Here you specify that the exact time a break occurs must be taken into account.

Dates to be specified

Here you specify that when you create or change an order the user must enter schedules dates (production dates) instead of basic dates.

Move order

Here you specify whether the order can be moved if partially confirmed operations exist.

In reduction you specify

whether in the order or in the collective order all the operations are to be reduced or only those along the critical path.

Reduction along the critical path is only possible for networks, production orders and planned orders with parallel sequences and for collective orders that contain production orders or planned orders.

up to which maximum reduction level the reduction takes place

to what percentage the float before and after production in every reduction level is to be reduced.

Note

Note that scheduling is always carried out for all scheduling levels that you have specified. For example, if you make changes in the order that are relevant to scheduling (basic dates, quantities) and schedule it again then scheduling is carried out not only for detailed planning but also for production-rate and rough-cut planning. This is very performance-intensive because data must be read from the database. Therefore it is recommended that you only maintain levels relevant to scheduling.

Whereas you can choose between several scheduling types for detailed scheduling, rough-cut and production-rate scheduling always use backwardscheduling. Reductions are also only relevant for detailed scheduling.
