Exceptions in ABAP statements can that can be handled can be caught using the predefined exception classes listed below. These exception classes are all the subclasses of class CX_DYNAMIC_CHECK and CX_NO_CHECK. From Release 6.10 they replace catchable runtime errors. The keyword documentation lists all the exceptions that can occur for each statement.
To improve the structure, intermediate abstract classes were introduced so that groups of exceptions can be caught simultaneously.
Each exception class includes message texts, which you can display by choosing the Texts tab in the Class Builder. The following links open each exception class in the Class Builder.
