Purpose The Monitoring functionality allows a BzCtrl. User to define the quantitative and/or financial scope of a customs licence, authorisation or other customs-related permit and continuously monitor the extent to which that scope has been consumed. The functionality must support, in particular: Inward Processing authorisations; End Use authorisations; AGRIM/import licences; other licences or authorisations where quantities and/or values are limited; automated consumption of the available scope based on customs declarations; manual and API-based input; aggregation of multiple declarations into monitoring totals; drill-down from an aggregate figure to the underlying declarations; storage of supporting documentation; configurable threshold notifications. The core principle is: Authorised scope → actual declarations → calculated consumption → remaining scope → evidence/documentation The Monitoring functionality should therefore provide both an operational overview and an auditable trail.
