You can reserve parts automatically in four ways: line-by-line, order-by-order, shipment-by-shipment, or via a batch job . When reserving automatically the system will reserve the ordered quantity according to the automatic reservation logic i.e. according to rules configured for FIFO, zone ranking, handling units etc. This is described in detail in the About Reservation Management. The order-by order reservation is performed on the Reserve Customer Orders page. The line-by-line reservation is performed on the Reserve Customer Order Lines page. The batch job is performed on the Create Customer Order Reservations page. The shipment-by-shipment reservation is performed in the different shipment pages.
Use this activity to handle order lines that were not reserved automatically. When running the automatic reservation function, the system will try to reserve the ordered according to settings done on the Automatic Reservation tab in Site/Warehouse Management page. If there are not enough parts available at stock the customer order will be stopped in the order flow and it will appear on Handle Customer Order Shortages.
You can re-plan and solve the shortage problem on your order/order lines and shipment/shipment lines either by advancing the delivery date or reducing the quantity on the order line. The reduced quantity must be greater than zero (0). To handle a shortage of 100% the order/order line must be cancelled.
Whenever you have resolved the shortage problems, you could re-run the reservation function by clicking Reserve Line.
The shortage on the customer order line/shipment line is resolved and the order/shipment is ready to continue in the order flow/shipment flow defined for the order type/shipment type.
