Specifying the Planning DirectionYou use the planning direction to control the direction in which the system starting at the desired scheduling date searches for a scheduling date for an operation or order. The system only searches in the planning period , that is, depending on the planning direction up to the earliest possible or latest possible scheduling date.
You have the following possible planning directions:
Planning direction forwards
Planning direction backwards
Planning direction forwards with reverse
Planning direction backwards with reverse
Planning Direction with Reverse
If the system does no find a scheduling date up to the earliest or latest possible scheduling date in the planning direction, it switches the planning direction and tries to schedule the operation or order as close as possible to the desired date in the other planning direction. If this is not possible, the system does not execute scheduling or rescheduling.
The availability date of the order product is decisive when creating orders. Here you typically select the planning direction backwards with reverse in order for scheduling to succeed. The default date for the reversal of the planning direction is the current date plus or minus the offset time. If you create an order manually, you can specify a reversal date.
