What is ABAP?
ABAP, which stands for “Advanced Business Application Programming”, is the proprietary programming language of SAP, a leading provider of business software. This programming language was developed specifically for mass data processing in commercial applications and has been the standard programming language for SAP modules since 1990. Originally, the abbreviation “ABAP” stood for “General Report Application Processor”, as this programming language could only be used to develop customer-specific evaluation programs that could not make any changes to the database. Later, “Advanced Business Application Programming” became the official explanation of the acronym. The syntax of the ABAP programming language is similar to COBOL in some ways, but differs greatly from other programming languages such as Java, C or Python. As ABAP is a non-standardized programming language, it is only used in connection with SAP programs. In this environment, however, ABAP provides powerful concepts for the development of business applications. ABAP was designed from the outset to deal with mass data in a business context and therefore differs significantly from other programming languages and interfaces. SAP’s programming language is similar to COBOL in its syntax and was developed specifically for mass data processing in commercial applications. The introduction of SAP NetWeaver has expanded the development options by offering a process and programming environment for the Java programming language in addition to ABAP. This led to the establishment of a further application server on which the Java-based programs are implemented. ABAP is a vendor-specific development language from SAP that differs from other development languages in many respects. Thanks to the “friends” concept, for example, classes can be “friends” with each other and version management takes place internally. The ABAP OO extension supports both procedural and project-oriented programming models, offering developers many new possibilities in one central location. Invented in the early 1980s and subject to constant further development since then, ABAP is now used to program the SAP Application Server. The programming language thus forms the basis of all SAP systems. It allows SAP software products to be adapted to the exact requirements of customers — even when the system’s own customizing is no longer sufficient. In addition, ABAP can be used to write completely new business applications in order to integrate them into an existing SAP system. ABAP therefore offers a wide range of development possibilities and plays a decisive role in the customization and extension of SAP systems to meet the exact requirements of customers. The ABAP OO extension supports both procedural and project-oriented programming models, offering developers many new possibilities in one central location.
ABAP development and the role of ABAP WebDynpro and ABAP SQL Script
ABAP does not stand alone, but is highly integrated with other functions of the SAP NetWeaver ABAP Application Server. This includes various aspects that support and extend ABAP development.
ABAP development
ABAP is a vendor-specific development language from SAP that differs from other development languages in many ways. Development generally takes place on a shared system in which all developers work on the same development objects at the same time. ABAP is still an important part of the SAP technology stack and plays a crucial role in SAP products such as SAP S/4HANA and the SAP Cloud Platform.
ABAP WebDynpro
ABAP WebDynpro is a framework from SAP that makes it possible to develop user-friendly web applications. It provides an efficient way to create web-based user interfaces and is closely linked to ABAP development. ABAP WebDynpro enables developers to create interactive web applications that are seamlessly integrated into the SAP system.
ABAP SQL Script
ABAP SQL Script is an important part of ABAP development, especially in the context of SAP S/4HANA. With the introduction of SAP S/4HANA, the focus has shifted from command statements to a functional orientation. It is recommended to program in SAP S/4HANA with Native SQL (formerly Open SQL), as the source code has been moved from the programs to the database layer. This means that programming takes place directly on the database, which is no longer possible with the familiar SAP ABAP. Developers therefore had to learn and use SQLScript as a new programming language for SAP S/4HANA. The targeted integration of ABAP WebDynpro and ABAP SQL Script into ABAP development opens up a wide range of possibilities for developers to create user-friendly web applications and make optimum use of the performance of SAP S/4HANA.
FAQ
How does ABAP compare with modern programming languages such as Python or JavaScript in terms of performance and efficiency?
Compared to modern programming languages such as Python or JavaScript, ABAP is specially tailored to the requirements of large amounts of company data in terms of performance and efficiency. It is less universal, but ideal for SAP-specific applications.
What are the specific advantages of the “Friends” concept in ABAP and how is it used in real SAP projects?
The “Friends” concept in ABAP enables closer and more secure collaboration between classes, which promotes a modular and maintainable code base in the context of large, complex SAP systems.
How has the introduction of ABAP OO impacted the flexibility and scalability of SAP applications, and are there examples of this impact?
The introduction of ABAP OO, or object-oriented ABAP, has significantly improved the flexibility and scalability of SAP applications by enabling developers to utilize modern software development practices within the SAP environment. This has led to more efficient development and increased the adaptability of systems to specific business requirements.
