What is ABAP
ABAP
the Advanced Business Application Programming is a programming language
for developing (to tailor and enhance SAP applications) applications for
the SAP R/3 system. ABAP is one of many application-specific
fourth-generation languages (4GLs) first developed in the 1980s. By
2001, all but the most basic functions were written in ABAP. In 1999,
SAP released an object-oriented extension to ABAP called ABAP Objects,
along with R/3 release 4.5.
ABAP/4 is the language created by SAP AG for
implementation and customization of their R/3 system. The rough English
translation of the acronym would be A Business Application Programming
language, version 4. It is a block-structured language.
ABAP/4 contains some highly report-oriented
event-driven control structures. For instance, events can be defined
for:
INITIALIZATION.
START-OF-SELECTION.
END-OF-SELECTION.
AT NEW-PAGE.
AT END-OF-PAGE.
