This field is filled automatically if a change was made to the selected purchase line. You cannot modify the field.

Note: The check box is not selected if a change was made to the purchase offer header or the purchase order header, for example if the contact has changed. This check box only alerts users to changes directly related to an order.

This check box is selected automatically if receipts have been registered for the selected purchase order or purchase order line, or if purchase invoices have been processed. You cannot modify the field.

This is the date on which the part must be present for stocking, production or sales purposes. If you are using receipt schedules, you can register the (partial) deliveries in which you expect to receive the quantity of goods ordered.

If you are using a receipt schedule, and then change the receipt date, a warning will appear alerting you to the fact that the receipt schedule contains multiple lines. The reason is that only the date on the first receipt schedule line is automatically modified.
