Source Code Organization
ABAP source code is saved in the ABAP Repository in the central database
of an AS ABAP , and not in source code files like in most other
programming environments. Source codes can be split into individual
units by using include programs. There are also
macros that are handled for callable modularization units in the
context of these guidelines.
