ABAP Runtime Environment (BC-ABA)

Special class used as the basis for handleable exceptions. When an exception is raised, an object of an exception class is raised. There are predefined exception cASlasses for exceptions of the runtime environment, and self-defined exception classes for custom applications. The superclasses for all exception classes are CX_STATIC_CHECK, CX_DYNAMIC_CHECK, or CX_NO_CHECK. These are used to divide exceptions into exception categories.
