Division 1.6.2 Automatic deletion of data

Where the national system enables the automatic transfer of national alerts to SIS, as set out in the previous paragraph, the deletion of a SIS-related alert in the national database should also lead to an automatic deletion of its SIS equivalent.

Since multiple alerts are not allowed, it is recommended that wherever possible and necessary, second and subsequent alerts on the same person are kept available at national level so that they can be introduced when the first alert on this person expires.
