How do you debug and troubleshoot X++ code?

There are several ways to debug and troubleshoot X++ code in Microsoft Dynamics 365 for Finance and Operations (D365). Some of the most common methods include:

• Using the built-in Debugger: D365 provides a built-in debugger that allows you to set breakpoints, step through your code, and inspect the values of variables and expressions. You can access the debugger by clicking on the Debug button in the development environment or by using the keyboard shortcut (F5).

• Using the Infolog: The Infolog is a built-in feature in D365 that allows you to view messages, warnings, and errors that are generated by your code. You can access the Infolog by clicking on the Infolog button in the development environment or by using the keyboard shortcut (Ctrl+Shift+I).

• Using the info method: The info method can be used to write messages to the Infolog, which can help you to understand the flow of execution and the values of variables during the execution of your code.

• Using the pause method: The pause method can be used to pause the execution of your code and wait for the user to press a key before continuing. This can be useful when you want to inspect the state of your code at a specific point.

• Using the breakpoint method: The breakpoint method can be used to insert a breakpoint into your code, which will cause the debugger to start when the breakpoint is reached. (F9)

  If you want to see the value inside any field then hover your mouse to to the field then you will be able see the value inside it.

• Using the throw statement: The throw statement can be used to generate an error that can be caught and handled by the try-catch statement

• Using the print statement: The print statement can be used to print a message to the console.

It's worth noting that, when debugging and troubleshooting X++ code, it's important to have a clear understanding of the problem and the expected behavior, and to use a systematic and logical approach to eliminate potential causes and identify the root cause of the problem. It's also important to test your code thoroughly before deployment and to have a good understanding of the codebase and the environment in which the code runs.
