Logic - Departure Report

Initial Port Call Locator
If vessel is reporting voyage reference number and reason for call:
The first port call for reported vessel code, reference number, reason for call and port that is not budget and not estimate.
If not port call is found then use exception: No port call found for this combination of vessel, voyage number, reason for call and port where departure fixed is not set.

If vessel is not reporting voyage reference number and reason for call:
The first port call for a vessel code that is not budget, not estimate, not redelivery, event is departure, event log date (departure date) > report date from vessel report.
If no port call is found then use exception: No departure port call found for the reported date and vessel.
A port call in Dataloy VMS can be registered multiple times after each other with different reason for calls. The Dataloy VRS rule for Departure Reports is to update arrival and berthing date for the first port call that is not a redelivery port call and the departure date for the last port call that is not a redelivery port call. The report should be inserted to the last port call. This action also controls if the departure date of the previous port call is fixed. If the departure date for a previous port call is not fixed, then VRS will assume that this is the port call to update (see Step 2).
