ABENSYSTEM_FIELDS_GDL - SYSTEM FIELDS GDL

System Fields

An ABAP program can request the state of the ABAP runtime framework using the system fields. From a technical viewpoint, these system fields are a set of built-in variables (the components of the built-in sy structure with the data type SYST from ABAP Dictionary) that always exist when the program is running.

The system field sy-repid is an exception. This field indicates the name of the program currently running. In this case, we are dealing with a built-in constant and not a component of the built-in sy structure.
