Service Resources are records that represent thepeople or equipment that perform field service tasks[199].
Permission Set Licenses are records that grant users access to specific features or apps such as Salesforce Field Service[200]. Creating one Service Resource and assigning the relevant Permission Set Licenses would allow Universal Containers to configure Salesforce Field Service to support an employee who performs the role of a Dispatcher and a Technician by creating a service resource record for the employee and assigning them the Salesforce FieldService Dispatcher and Mobile permission set licenses[201]. Creating two Service Resources and assigning them to the employee would not work because an employee can only be associated with one service resource record[202]. Creating one Service Resource andassigning the Technician and Dispatcher role would not work because roles are records that define the level of access users have to data in an organization hierarchy[203]. Creating two Skills records and assign them to the Service Resource record would not work because skills are records that define specific abilities or qualifications that service resources have and do not affect their access to features or apps[204].

Working Location Enable Primary is a setting on the Working Territories work rule that defines whether resources should be matched with service appointments based on their primary territory only or any territory they belong to[186]. Match Territory is a work rule that defines whether resources shouldbe matched with service appointments based on their territories[187]. Selecting Working Location Enable Primary on the Working Territories Work Rule and including the Match Territory Work Rule would allow Universal Containers' scheduling policy to look atboth primary and secondary service territories by enabling matching resources with service appointments based on any territory they belong to and prioritizing matching resources with service appointments based on their territories. Removing the Match Territory Work Rule would not allow Universal Containers' scheduling policy to look at both primary and secondary service territories because it would disable matching resources with service appointments based on their territories. Deselecting Working LocationEnable Primary on the Working Territories Work Rule would not affect Universal Containers' scheduling policy because it is already deselected by default.

Crew Management is a feature that allows creating and managing crews of multiple service resources who share the same service appointments[163]. The Preferred Resource service objective is ignored for active Crew Members because it only applies to individual resources and not crews[164]. Capacity-based scheduling is not supported for Service Crews because crews do not have capacity limits and can be assigned unlimited service appointments[165]. A service resource can be a member of multiple crews and can switch between them depending on their availability and skills[166]. Salesforce Field Service does not consider the Recommended Crew Size when assigning appointments because it only considers the Required Crew Size which indicates the minimum number of crew members needed for a service appointment[167].

Customer Entitlements are records that specify customers' support terms based on their contracts or warranties
[38].

Customer Working Hours are records that define when customers are available for service appointments[41].
Service Urgency is a field on the work order object that indicates how quickly a work order must be completed
