Runtime errors identify situations in which the system cannot continue running an ABAP program and has to terminate it. During the execution of ABAP programs, runtime errors may occur in one of the following two cases:
Each runtime error is identified by a name and assigned to a specific error situation. When a program terminates due to a runtime error, the system issues a short dump, which indicates the name of the runtime error, the associated exception class, contents of data objects, active calls, control structures, and so on, and allows the user to navigate directly to the ABAP Debugger. By default, short dumps are retained for a period of 14 days in the system and managed using the transaction ST22. You can change the settings for the short dump in the profile parameter rdisp/verbose_level.
