Rocketship syncs with Autotask Holiday Sets (per Internal Location) daily.
You can view the current list of holidays from:
The Holidays page in DispatchBoard, or
Your Calendar.
Holiday handling is configured in Next Activity Recipes.
Here you can:
Enable or disable holiday support.
Enable or disable external appointments (usually Office 365 appointments for each resource).
Ticket Routing Rules will honor holidays based on which Next Activity Recipe they use.
Example:
If you create a rule called HelpDesk and assign it the recipe 1 Hour Block, Include Holidays, the Ticket Routing module will ignore holidays.
