Overview of the Components of Application Programs in SAP ABAP

This overview describes application programming in the R/3 System. All application programs, along with parts of the R/3 Basis system, are written in the ABAP Workbench using ABAP, SAP’s programming language. The individual components of application programs are stored in a special section of the database called the R/3 Repository. The R/3 Repository serves as a central store for all of the development objects in the R/3 System. The following sections of this documentation cover the basics and characteristics of application programming.
