If one or more constraints are provided for a recurring trigger:
•Upon activation, the system waits until the trigger’s initial instance’s scheduled date and time.
•At that time, it commences checking database count constraints at a frequency accordant with a system configuration setting (TriggerCheckCriteriaInterval).
•The trigger fires when all constraints are satisfied:
o All database count constraints are met.
o Calls received from all external services.
•Following execution of the initial instance, the trigger commences checking constraints in accordance with its configuration settings.
