1.All "Incidents" occurred are transmitted to the office of departure. Only those "Transhipments" marked "not yet sent" (i.e. flag "Already in the system" in a message of arrival notification or a new box created for this purpose on the TRANSIT ACCOMPANYING DOCUMENT) are transmitted to the office of departure.
2. The data is sent as a set of records of which a large part describes the characteristics of the data (country, year, economic activity, etc.). The data itself is a number which can be linked to flags and explanatory footnotes used for example to describe aggregations of NACE codes. Confidential data should be sent with the true value being recorded in the value field and a flag indicating the nature of the confidential data being added to the record.
