System Variables in ABAP Debugger

System Variables in ABAP Debugger

At the bottom of the debugger screen, are 3 fields, named ‘SY-SUBRC’, ‘SY-TABIX’ and ‘SY-DBCNT’
System Variables in ABAP Debugger






Note that the value boxes here are greyed-out, meaning that they cannot be changed manually. These are system fields, belonging to a table called SYST. This system table in-cludes many system fields which are filled in at runtime. These system fields are filled in automatically while the program is executed. Most statements within ABAP will cause these system fields to be filled with 0 when executed successfully. It is important to re-member that these fields are completely statement-dependent, meaning that they will contain different values depending on which statement is executed. These system codes and variables will be looked at in greater depth later
