Settings for Scheduling
Settings in Customizing
You find the following Customizing activities in Customizing for Shop Floor Control in the Operations ®
Scheduling section, unless otherwise stated.The scheduling parameters are defined per order type, plant and production scheduler (from the material master). They cover many control parameters that are described in the corresponding places in the documentation (see Scheduling Parameters).
The scheduling type determines which dates must be entered during scheduling and which dates are determined by the system (see Scheduling Type).
To calculate the duration of individual operation segments (setup, process, teardown), the formula parameters and formulas are used (see Calculation of the Operation Segments). They are assigned to the work center.
The standard value key determines the meaning of the individual standard values (see Calculation of the Operation Segments). It is assigned to the work center.
Performance efficiency rates are assigned to the individual standard values in the work center. They specify the relationship between the specified target and actual time.
You define the order float in the scheduling margin key, (see Scheduling at Order Level). The scheduling margin key is copied from the material master.
If the move time defined in the routing is insufficient then the move time can be defined in a move time matrix (see Date Determination at Operation Level).
The reduction strategy is assigned to the individual operations in the routing. If an order cannot be executed within the specified order dates, the system tries to shorten the lead time of an order using the entries from the reduction strategy (see Reduction Measures and Reduction via the Critical Path).
You can carry out a very detailed definition of the operating time of a work center using a shift sequence. You define the shift sequence in Customizing for Shop Floor Control by choosing Operations ® Capacity Planning ® Define Shift Sequence.
The calendar defines the workdays and non-working days. It is assigned to the capacities in the work center. You maintain the calendar in Customizing by choosing General Settings ® Maintain Calendar.
You can enter a reduction strategy here. When an order is created, this reduction strategy is assigned to all operations that are not assigned a reduction strategy in the routing.
You maintain the order type-dependent parameters in Customizing for Shop Floor Control by choosing Master Data ® Order ® Order-Type Dependent Parameters.
In the control key you can define whether and how each operation is scheduled and whether capacity requirements are to be generated (see Control Key for Operations). The control key is assigned to the individual operations in the routing.
You maintain the control key for operations in Customizing for Shop Floor Control, by choosing Master Data ® Routing Data ® Define Control Key.
Settings in Master Data
The settings described here are transferred to the production order and, as a rule, can still be changed there.
If wait times are defined in the routing and in the work center, then the definition in the routing takes precedence.
The determination of the requirements dates for directly produced components in collective orders can be influenced in the bill of material:
