How the planner plans an order

When the Planner plans an order, it first searches backward from the due date to allocate the needed quantity. This is referred to as pull planning. If the plan cannot find sufficient on-hand inventory/planned supplies, or projects a start date for a planned order that is in the past, the order is late. The Planner instead searches forward (or push plans) from the current date.

Note: The Planner considers the Time Fence and Pull-up Order options during the planning process; therefore, it may perform up to eight planning passes (for example, plan with Time Fence enabled; if that fails, plan with Time Fence disabled, and so on). These additional planning passes are described in “Defining a Time Fence for Inventory/Supply Usage”.
