System Fields

An ABAP program can request the status of the ABAP runtime environment using the system fields. From a technical viewpoint, these system fields are a set of predefined variables - the components of the predefined sy structure of data type SYST from the ABAP Dictionary - that are always available while 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 predefined constant and not a component of the predefined sy structure.
