Exception handling


Exception handling is a new concept in Microsoft Dynamics NAV. It was imported from .NET, and is now gaining popularity among the C/AL programmers because of its effective usage.

Like C#, for exception handling, we use the Try function. The Try functions are the new additions to the function library, which enable you to handle errors that occur in the application during runtime. Here we are not dealing with compile time issues. For example, the message Error Returned: Divisible by Zero Error. is always a critical error, and should be handled in order to be avoided. This also stops the system from entering into the unsafe state. Like C sharp and other rich programming languages, the Try functions in C/AL provide easy-to-understand error messages, which can also be dynamic and directly generated by the system. This feature helps us preplan those errors and present better descriptive errors to the users.
