System Fields

There is a range of system fields within ABAP/4. You can display a list of them with their definitions by entering the header command SHOW SY. If you are in PC mode, press the     pushbutton and enter table structure SY.

• In programs, you address system fields by entering SY-<field name>.
  
• The SY-SUBRC or Return Code field is used frequently when selecting records from a table because a non-zero value for this field indicates that NO records were found in the specified table. This use of the SY-SUBRC field is illustrated previously with the SELECT with WHERE clause.
