What determines the resource schedule if the Schedules related list and Schedule field are both empty?

ServiceNow Resource Management determines a user's schedule based on a specific order of precedence. When a schedule is not explicitly defined on the user record—neither in the 'Schedules' related list nor in the 'Schedule' field—the system falls back to a predefined system property. The com.snc.resourcemanagement.defaultschedule property specifies the name of the schedule to be used as the default for any resource without an assigned schedule. This ensures that all resources have a defined schedule for accurate capacity and availability calculations.

B. Effort type (FTE or Person Days) is used for calculating and planning effort, not for defining a resource's working days and hours.
C. While Project Management uses schedules, the specific fallback mechanism for a resource without a schedule is governed by a Resource Management property, not a generic "Project Management Schedule".
D. This property defines the number of hours in a standard workday for FTE calculations, but it does not define the entire schedule (e.g., which days are workdays, holidays).

1. ServiceNow Product Documentation: Resource Management properties. The documentation lists the property com.snc.resourcemanagement.defaultschedule and its description: "Name of the schedule to be used for a resource if the resource does not have any schedule associated."

2. ServiceNow Product Documentation: Resource schedules. This document outlines the order of precedence for deriving a resource's schedule: "The resource schedule is derived in the following order of precedence: 1. Schedules in the Schedules related list on the User form. 2. Schedule in the Schedule field on the User form. 3. Schedule specified in the resource management property: Default Schedule Name (com.snc.resourcemanagement.defaultschedule)."
