Universal Containers wants to limit their Technicians’ view of Work Orders and Service Appointments in...

For this scenario, Salesforce Field Service should use Page Layouts. Field Service Mobile uses assigned layouts to determine which Work Order and Service Appointment fields and related information technicians see. Appropriate profile/record-type layout assignments therefore provide the standard way to simplify the mobile record view.

Field Service Mobile is designed for technicians working in changing connectivity conditions. Standard page layouts, quick actions, flows, Service Reports, Knowledge, and supported mobile extensions should be used before introducing custom Visualforce or bespoke components because the native features participate in synchronization, offline behavior, and the Field Service security model.

The alternatives address different parts of the Field Service model. Field Sets apply to specific configurable surfaces, Visualforce is custom development, and Mini-Page Layouts do not drive the normal Field Service Mobile record experience.

This approach keeps the implementation aligned with the standard Field Service data model and avoids unnecessary customization. Study Guide reference: Configuring Mobility — Field Service Mobile; Page Layouts; technician record views.
