In this example, all items are relevant for the availability check.

The sales order has three items, which are to be delivered at the same time. Therefore, they are assigned to the same delivery group.

Note that item 30 has the latest confirmed delivery date (December 15). This date is used as the confirmed delivery date for each item. The system therefore creates a delivery group schedule line for each item, with the confirmed delivery date December 15. The example below shows the schedule lines for item 20, including the delivery group schedule line with the confirmed delivery date December 15.
