A developer discovers that a calculated property value is returning an unexpected result.

When diagnosing an issue with a calculated property value using the Tracer tool:

B. Breakpoints. This feature allows you to pause the execution at certain points, enabling you to inspect the processing of the rules and properties, which is helpful in identifying where and why a property is not calculating as expected.

C. The Watch function. By watching specific properties, you can monitor changes to their values in real time as the process executes, which helps in determining the point at which the unexpected result occurs, all with minimal overhead on application performance.
