Salesforce Maps Advanced provides powerful route and schedule optimization for field representatives. Its capabilities are designed to create the most efficient plans while adhering to business rules. The system incorporates real-time and predictive traffic data (A) to calculate accurate travel times and avoid delays. The core of the tool is its constraint-based routing engine (B), which allows planners to define rules such as working hours, break times, and skills. A critical constraint for store visits is respecting Visit Windows (C), which ensures that representatives arrive at a location only during its specified hours of operation or appointment times. These three capabilities work together to generate realistic and productive daily schedules.

D. Visit Prioritization: While Salesforce Maps Advanced can prioritize visits, this is a specific rule handled by the broader Constraint based Routing (B) engine and is less foundational than the core engine itself or hard constraints like visit windows.

E. Gantt-chart Routing: This is not a standard Salesforce feature or industry term for a routing capability. A Gantt chart is a method for visualizing a schedule, not a mechanism for creating one.

1. Salesforce Help, Optimize Routes with Salesforce Maps Advanced: This document explicitly states that the optimization engine "considers various factors, such as work hours, travel time, stop duration, traffic conditions, and visit priorities." This confirms the use of traffic data (A) and the general principle of constraint-based logic (B).

2. Salesforce Help, Salesforce Maps Route and Schedule Optimization: This guide details the scheduling policies and work rules that form the basis of constraint-based routing. Under "Field Service Settings," it describes the use of an "Arrival Window Start Field" and "Arrival Window End Field" for Service Appointments, which directly corresponds to the Visit Windows capability (C).

3. Salesforce Help, Routing and Optimization Services: This documentation for the underlying engine explains the different types of constraints (called "work rules") that can be applied, such as "Match Skills," "Time-Bound," and "Service Territory." This confirms the fundamental nature of constraint-based routing (B) as the core capability.
