# Commission Decision of 4 March 2008 adopting the SIRENE Manual and other implementing measures for the second generation Schengen Information System (SIS II) (notified under document number C(2008) 774) (Only the Bulgarian, Czech, Dutch, Estonian, Finnish, French, German, Greek, Hungarian, Italian, Latvian, Lithuanian, Maltese, Polish, Portuguese, Romanian, Slovak, Slovenian, Spanish and Swedish texts are authentic) (2008/333/EC), Division 2.9: Deleting when the conditions for maintaining the alert cease to be met

Extent: E+W+S+N.I.

Alerts entered into SIS II shall be kept only for the time required to meet the purposes for which they were supplied.
Excluding the cases after a hit, an alert shall be deleted either automatically by the CS-SIS (once the expiry date has passed) or directly by the service that entered the alert in the SIS II (once the conditions for the alert being maintained no longer apply).
In both instances the CS-SIS deletion message shall be processed automatically by the N.SIS II.
Member States have the possibility to subscribe to an automatic notification of the deletion of an alert issued by another Member State.
