Settings for Planning Plant and Order Type
During scheduling, the lead times for the operations (Duration field) are totaled and then either added to the basic start date (forwards scheduling) or subtracted from the basic end date (backwards scheduling). The start or end dates calculated in this way can deviate from the basic dates.
For each order type, you can define the standard scheduling type. However, this can be changed on the header data screen for the maintenance order. Each scheduling type refers to a scheduling method, for example, forward scheduling, backward scheduling, current date scheduling, or no scheduling.
Adjust basic dates means that the date entries scheduled always have priority over the basic dates.
Automatic scheduling means that the system always schedules the order when you save it.
Scheduling including breaks means that the break times from the work center masters are considered. If the indicator is not set, the total break time is distributed proportionally. The scheduling including breaks can only be used in connection with a shift sequence with scheduled breaks (in maintenance, this is not usual).
Order shift means that if you change the basic dates when an order is being executed, the system always uses the new basic dates for scheduling purposes, rather than the actual dates entered so far.
Scheduling Types
The capacity loads that are already available are considered during capacity scheduling.
Only those work centers that have the Relevant for Capacity Scheduling indicator are involved in capacity scheduling. For each operation to be scheduled, the system checks whether sufficient free capacity is available for it on the date calculated. If sufficient capacity is available, the operation is scheduled. If sufficient capacity is not available, the operation is shifted to a date when capacity problems do not arise.
