You are implementing Microsoft Dynamics 365 Field Service. The customer wants to use the system to capture changes in various system readings when a technician is onsite servicing an asset. What should you recommend?

Asset Properties are designed to define specific data points or readings related to an asset, such as temperature, pressure, or vibration levels. When a technician updates a property's value during a service visit, the system automatically creates a time-stamped "Property Log" entry. This log provides a complete historical record of the readings for that specific property, allowing for analysis and trend monitoring. This directly fulfills the customer's requirement to capture changes in system readings over time.

A. Asset categories are used for grouping similar assets for reporting and management, not for tracking individual, variable readings.
B. "Asset Category Log" is not a standard entity in Dynamics 365 Field Service; this option is a distractor.
C. Using unstructured notes makes it impossible to systematically track, report on, or analyze specific numerical readings over time.
