Ok, I worked out the “Application Screen Changed” event:
Possible values for CurrentScreen and PreviousScreen:
Nothing
LoginScreen
Navigation
WorkPeriods
EntityView
PaymentView
TicketView
TicketListView
AccountView
InventoryView
MarketView
ReportView
Management
So just set constraint CurrentScreen - equals - Management
for a rule to work when entering the Management screen
or
PreviousScreen - equals - Management
for a rule to work when leaving the Management screen
