VMS - What data is used as the identifier to determine which port the Vessel Message is assigned to?

VMS recognizes the Vessel Name and Date as the identifier to determine which port the Vessel Message should be assigned to. VMS does not use the Port Name or Voyage Number as the identifier. Please see the following scenario for a better understanding.

If the date does not meet the criteria stated in the BRACKETS, it is likely to be assigned to the next port.
