Should the arrival time of a truck change, then you can adjust the ETA from the overview screen. Click on the timeslot to adjust the ETA.
Regarding APM Maasvlakte II, APM Terminals Rotterdam, Rotterdam World Gateway or Rotterdam Short Sea Terminals, the linked containers are pre-notified at the terminal again and the new status/TAR information is retrieved after the new ETA has been submitted. Hutchison Ports ECT Delta en Hutchison Ports ECT Euromax do not support the changing of pre-notifications. At these terminals, it is only possible to cancel the notification and reuse it for a new pre-notification or create a completely new one.
