I have some confusion here as well. But for each tier you can specify when they kick off. So for tier 1 it could be set to fire at 0+ hours after being late (ours seems to run on the hour). Then tier 2 could be at 2 hours later and have a different set of people being notified. Then Tier 3 could be 1 or how ever many hours after that.
If the notifications are different for the tiers do the people in the previous tiers also get notified?
Also how does the persons or queues normal business
So, that tells me that there is no way to have multiple authorizations use different escalation paths? For example, if one authorization has a 1 hour escalation and another one has 3 hours before escalating?
