Diagnosis
You have deleted assignments for the route schedule determination,which has led to an automatic deletion of lines in the itinerary. (Thishappens, for example, if you delete all the assignments to a ship-toparty in the route schedule determination; in this case, this ship-toparty must also be deleted in the itinerary.) By deleting a line, thetravel time for the following line may possibly change; the systemprovides help in this case in that only the travel times of therespective lines are ready for input, and all other lines are notaccessible.

Procedure
Adapt the travel times, if necessary.
