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

When diagnosing a problem with a calculated property value that is returning an unexpected result, the Trace tool in Pega is invaluable for investigating the issue without impacting application performance. Specifically, the use of Breakpoints and the Watch function can provide deep insights:

A. Breakpoints: Allow you to pause the execution of the process at specific points, making it easier to examine the state and values of properties at those moments. This can help in identifying where in the process the unexpected value is being set or calculated.

C. The Watch function: Enables you to monitor the values of specified properties as the process executes. This can be particularly useful for tracking how the value of the calculated property changes over time or at specific steps in the process, helping to pinpoint the cause of the unexpected result.

The Event monitor (B) and The Clipboard tool (D) are valuable features within Pega's diagnostic tools suite, but they serve different purposes. The Event monitor is more about tracking and analyzing system events, while The Clipboard tool is used for viewing and manipulating the current state of clipboard pages, not specifically designed for diagnosing problems with property calculations in the same direct manner as Breakpoints and the Watch function.
