A system which is being supplied with transports should always remain consistent. For this purpose, you must specify deadlines by which developers must release their transports. You can close the import queue to prevent transports released after the deadline from being imported with the next import of all transports.
Transports which are released after the import queue has been closed are placed in the queue after a so-called stop mark. They will only be marked for import after the next import of all transports has been completed. During the next import of all transports in the queue only the transports before the stop mark are imported. The stop mark will be removed automatically after the import has finished.
