ABAP Advanced Business Application Programming, originally Allgemeiner Berichts Aufbereitungs Prozessor, German for general report creation processor1 is a high level programming language created by the German software company SAP SE. It is currently positioned, alongside Java, as the language for programming the SAP Application Server, which is part of the Net. Weaver platform for building business applications. IntroductioneditABAP is one of the many application specific fourth generation languages 4. GLs first developed in the 1. It was originally the report language for SAP R2, a platform that enabled large corporations to build mainframe business applications for materials management and financial and management accounting. ABAP used to be an abbreviation of Allgemeiner Berichts. Aufbereitungs. Prozessor, German for generic report preparation processor, but was later renamed to the English Advanced Business Application Programming. ABAP was one of the first languages to include the concept of Logical Databases LDBs, which provides a high level of abstraction from the basic database levels. The ABAP language was originally used by developers to develop the SAP R3 platform. It was also intended to be used by SAP customers to enhance SAP applications customers can develop custom reports and interfaces with ABAP programming. The language was geared towards more technical customers with programming experience. ABAP remains as the language for creating programs for the client server R3 system, which SAP first released in 1. As computer hardware evolved through the 1. SAPs applications and systems were written in ABAP. By 2. 00. 1, all but the most basic functions were written in ABAP. In 1. 99. 9, SAP released an object oriented extension to ABAP called ABAP Objects, along with R3 release 4. SAPs current development platform Net. Weaver supports both ABAP and Java. ABAP has an abstraction between the business applications, the operating system and database. This ensures that applications do not depend directly upon a specific server or database platform and can easily be ported from one platform to another. SAP Netweaver currently runs on UNIX AIX, HP UX, Solaris, Linux, Microsoft Windows, i. OS on IBM System i formerly i. Series, AS4. 00, and zOS on IBM System z formerly z. Series, S3. 90. Supported databases are IBM DB2, Informix, Max. DB, Oracle, and Microsoft SQL Server support for Informix was discontinued in SAP Basis release 7. ABAP runtime environmenteditAll ABAP programs reside inside the SAP database. They are not stored in separate external files like Java or C programs. In the database all ABAP code exists in two forms source code, which can be viewed and edited with the ABAP Workbench tools and generated code, a binary representation somewhat comparable with Java bytecode. ABAP programs execute under the control of the runtime system, which is part of the SAP kernel. The runtime system is responsible for processing ABAP statements, controlling the flow logic of screens and responding to events such as a user clicking on a screen button in this respect it can be seen as a Virtual Machine comparable with the Java VM. A key component of the ABAP runtime system is the Database Interface, which turns database independent ABAP statements Open SQL into statements understood by the underlying DBMS Native SQL. The database interface handles all the communication with the relational database on behalf of ABAP programs It also contains extra features such as buffering of tables and frequently accessed data in the local memory of the application server. SAP systems and landscapeseditAll SAP data exists and all SAP software runs in the context of a SAP system. A system consists of a central relational database and one or more application instances accessing the data and programs in this database. An SAP system contains at least one instance but may contain more, mostly for reasons of sizing and performance. In a system with multiple instances, load balancing mechanisms ensure that the load is spread evenly over the available application servers. Installations of the Web Application Server landscapes typically consist of three systems one for development one for testing and quality assurance and one for production. The landscape may contain more systems e. QA nevertheless three is the most common configuration. ABAP programs are created and undergo first testing in the development system. Afterwards they are distributed to the other systems in the landscape. These actions take place under control of the Change and Transport System CTS, which is responsible for concurrency control e. QA and production systems. The Web Application Server consists of three layers the database layer the application layer and the presentation layer. These layers may run on the same or on different physical machines. The database layer contains the relational database and the database software. The application layer knowledge contains the instance or instances of the system. All application processes, including the business transactions and the ABAP development, run on the application layer. The presentation layer handles the interaction with users of the system. Online access to ABAP application servers can go via a proprietary graphical interface, which is called SAP GUI, or via a Web browser. Software layerseditABAP software is deployed in software components. Examples for these are SAPBASIS is the required technical base layer which is required in every ABAP system. SAPABA contains functionalities which is required for all kinds of business applications, like business partner and address management. SAPUI provides the functionality to create SAP UI5 applications. BBPCRM is an example for a business application, in this case the CRM application. SAP ABAP is an ERP programming language. TransactionseditA transaction in SAP terminology is the execution of a program. The normal way of executing ABAP code in the SAP system is by entering a transaction code for instance, VA0. Create Sales Order. Transactions can be called via system defined or user specific, role based menus. They can also be started by entering the transaction code directly into a command field, which is present in every SAP screen. Transactions can also be invoked programmatically by means of the ABAP statements CALL TRANSACTION and LEAVE TO TRANSACTION. The general notion of a transaction is called a Logical Unit of Work LUW in SAP terminology citation needed the short form of transaction code is T code. Types of ABAP programseditAs in other programming languages, an ABAP program is either an executable unit or a library, which provides reusable code to other programs and is not independently executable. ABAP distinguishes two types of executable programs Reports follow a relatively simple programming model whereby a user optionally enters a set of parameters e. SET of data and the program then uses the input parameters to produce a report in the form of an interactive list. The term report can be somewhat misleading in that reports can also be designed to modify data the reason why these programs are called reports is the list oriented nature of the output they produce. Module pools define more complex patterns of user interaction using a collection of screens. The term screen refers to the actual, physical image that the user sees.
