Salesforce Scheduler now supports adding up to 20 mandatory service resources to a single appointment in appointment booking flows. Now, when scheduling an appointment in the user interface, you can add more service resources and find the right slot. This change supports complex scheduling scenarios, such as tribunals, court hearings, panel reviews, team presentations, and so on.
Where: This change applies to Lightning Experience in Enterprise and Unlimited editions with Salesforce Scheduler enabled.
