Dates are synchronized when there is a change in the date for the order line or the order header, and when a rule synchronize dates between master order dates and dates on order line and schedules is configured.
The following four order dates are created for both the order line and the order header based on the requested and expected ship dates:
Every order date has an expected date, requested date, actual date, and committed date. These order dates are specified at either the order header or at the order line level. Requested dates for the order dates are synchronized with requested ship date, requested delivery date, and requested cancel date.
Expected order dates at the line level are synchronized with the expected shipment date, and the expected delivery date of the order line schedule. Expected Order Dates at the order header are synchronized with the expected shipment date and expected delivery date of all the order lines.
Order dates at header level are effected by the dates on the order header record and also by the schedule records for the whole order. Order dates at line level are effected by the dates on the order line record and also by the schedule records for that line.
