ABAP - Keyword Documentation
The ABAP keyword documentation describes the syntax and semantics of the keywords of programming languages provided by SAP on an Application Server ABAP (AS ABAP) of an ABAP system implementing an ABAP platform. It also provides an introductory description of the environment of these languages and of language-related frameworks and the corresponding system classes.
ABAP Dictionary is a persistent repository of metadata used to describe data types, database tables, views, and similar objects that can be used in development objects such as ABAP programs or CDS entities. This section of the ABAP keyword documentation provides a full description of the most important ABAP Dictionary objects that are relevant for the programming languages. It also includes documentation for the Dictionary DDL used to define certain dictionary objects in the ABAP Development Tools (ADT).
The ABAP Core Data Services (ABAP CDS) are the ABAP-specific implementation of SAP's CDS concept. They are used to develop data models that go far beyond the capabilities of ABAP Dictionary. This section of the ABAP keyword documentation introduces the concepts of ABAP CDS and provides full descriptions of the programming languages used to define CDS objects in the ABAP Development Tools (ADT), such as CDS DDL, CDS DCL, CDS SDL, or CDS BDL.
ABAP is the main programming language of the ABAP development environment (ABAP DE) provided by an ABAP platform. It is the namesake for the Application Server ABAP (or AS ABAP) and many of its components. ABAP is the programming interface of an AS ABAP and is used for the development of system programs and application programs that are usually based on objects in ABAP Dictionary or in ABAP CDS. This section of the ABAP keyword documentation provides a full description of the ABAP programming language and its object-oriented part, ABAP Objects. It also provides descriptions of the XML-based language elements for Simple Transformations and the language elements of the dynpro flow logic, which can be used only in combination with ABAP.
Rules and hints on using ABAP.
Overview of potential security risks in ABAP programs.
Rules on how to develop robust ABAP programs using released APIs.
List of release-specific changes and enhancements to ABAP and the other programming languages.
Terms in the ABAP environment, and their explanations.
Alphabetic index of the language elements of all programming languages described in the ABAP keyword documentation. If not noted otherwise, language elements are part of the ABAP programming language. Language elements in the other programming languages are noted accordingly.
Alphabetic index for searching by subject area.
Alphabetic list of executable ABAP example programs.
Hint
The programs and program extracts presented in the ABAP keyword documentation are only syntax examples and are not intended for direct use in a production system environment. The source texts of the examples are primarily intended to provide a better explanation and visualization of the syntax and semantics of ABAP statements and not to solve concrete programming tasks. For productive application programs, a dedicated solution should therefore always be worked out for each individual case.
The database tables of the flight data model used in the example programs can be filled using the program SAPBC_DATA_GENERATOR.
