To manually extract the billable events for the selected vessel visit(s):
In the Operations Vessel Visits Vessel Visits view, select the vessel visit(s) for which you want to extract the billable marine events. You can also create a filter to display the vessel visits you want to include in the billing extract and select the resulting rows. For example, you can create a filter to display the vessel visits that have the phase Departed.
In the Vessel Visits view or the Vessel Inspector for the selected vessel visit, click Actions.
Select the Extract Events option.
N4 displays a progress bar indicating the status of the extract.
After the extract is complete, in the Chargeable Marine Events view, click 
to see the extracted events.
All the extracted chargeable marine events are assigned the Status QUEUED.
N4 assigns a batch number to each extract. N4 also associates the batch number with the extracted event to indicate that it has already extracted the event. N4 will not extract this event the next time it selects the associated vessel visit for the extract. If N4 cannot extract an event, it assigns a negative value of the batch number. This prevents the extract to select the event repeatedly. You can use the All Events view to view the events with a negative batch number.
