Diagnosis
You have changed the pickup date.
When you create a delivery order the system uses the pickup date as thedefault delivery date for the individual schedule lines. If the pickupdate is changed later, the delivery date inthe schedule lines is not adjusted. This means that any manual changesthat might have been made in the meanwhile are not overwritten.

Procedure
Use the fast change function to adjust the delivery date in theschedule lines that haven't been delivered so that it matches thechanged pickup date.
