The Components of ABAP Application Programs
All ABAP applications, along with parts of SAP NetWeaver Application Server ABAP, are written in the ABAP Workbench development environment using ABAP (Advanced Business Application Programming) which is SAP's own programming language. The individual components of application programs are stored in a special section of the database which is used as the central storage for all development objects of the SAP System and is called the Repository. The following sections of this documentation cover the basics and characteristics of ABAP application programming.
