All imported sita messages about this landed (which is arrival flight + departure flight) can be seen altogether in this tab. Remember, in the flight related incoming sita tab, only those sita messages that are related with that flight (either arrival or departure) can be seen.
The import status column shows the status of the imported message. It is possible that a sita message might contain errors. An erroneous (non-standard, contains user made errors in its text, etc.) sita message is reported by the pre parser. Even these erroneous messages can be tracked in this screen manually.
