ABAP (Advanced Business Application Programming) is a 4th generation language developed by the German software company SAP AG. It is a high-level object-based programming language.

All R/3 applications have been developed with ABAP. ABAP/4 is used for software, exchange, adapting, inquiries and additional development of SAP applications. The ABAP/4 programming language provides the flexibility of application programmers to produce solutions suitable for their own companies in industrial environments. It meets all the needs of the ever-evolving ABAP/4 business environment.

Who can write ABAP?

ABAP is one of the first languages to include the concept of a logical database that provides a high-level abstraction from the base database level.

The ABAP programme language was first used by developers to develop the SAP R/3 platform. SAP customers were designing to use ABAP to develop SAP applications where customers could develop custom reports and interfaces.

It’s easy for programmers to learn, but it’s not a ideal tool for non-programmers. Programming capabilities including relationship database design and preferably object-oriented conceptual knowledge are required to create ABAP programs.

Where Does ABAP Work?

All ABAP programs are located in the SAP database. They are not stored in separate external files, such as Java and C++ programs. ABAP programs work 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 when the user clicks the screen button). One of the key components of the ABAP runtime system is the database interface that translates database-independent ABAP expressions (“open sql”) into statements (“native sql”) that dbms (database management system) at the base can understand. The database interface, on behalf of ABAP programs, handles all communication with the relationship database, but also includes extra features such as buffering frequently accessed data in the application server’s built-in memory.

SAP has three different layers. These are the presentation layer(gui), the application tier (programs work on top of this), and the database layer where all data is earned and stored from user-prepared situations and the commands that the end user gives from the presentation layer.

What is the connection between ABAP and SAP Parent Units?

SAP basically has 3 parent unit systems: Development, Testing, Live. ABAP codes are written in the development system. It is controlled in the test system. If approved, the codes are moved to the live system. If necessary for performance testing of codes, another parent unit is opened under the name of quality system on a server that has the same characteristics as the live system. At certain periods, data from the live system is copied to the quality system. As time passes, the test system used before loses importance and is turned off because the tests of new improvements are carried out in the quality system. Now the quality system is a replacement for the test system. In some projects, system design is done in the form of Development-Quality/Test-Live.

In some projects, the Development and Test parent volumes may be on the same server. Because ABAP objects (Workbench) are kept on a server-by-server basis, codes written in the development system, tables created, and so on also apply to the test system. Only the data in tables that are parent-dependent (if the table has a MANDT field) are different from the adaptations. In the same way, the codes approved in the test system are moved to the live system.

What are the uses of SAP ABAP?

The main use of ABAP is to make improvements on SAP in line with customer requests. For example, ABAP can be used if a customer requests any change or add-on to the SAP software.

Another purpose is to report and present the data on SAP in line with requests. For example, you own a factory and you want to report how much the goods you produce are sold daily, monthly or annually, at this point ABAP comes into play and a plugin is written to enable you to get this report.

In general, with ABAP, report programs that read the necessary information from the database and display it on the screen, fields required for adding records to the system, and user interfaces that enable data exchange between SAP systems can be written. In addition, one should not forget the multi-language support, which is another important feature.

It supports databases such as ABAP Open-Sql, Mssql and Oracle.

Who is a ABAP consultant, what does he do?

A person who develops various modules for sap with abap language, writes reports and designs outputs is called ABAP consultant. ABAP consultant either works for a company or creates his own client portfolio and continues his business life as a freelancer.

Who can be an ABAP consultant?

In order to create abap programs, relational database design and programming skills, preferably including object-oriented concept knowledge, are required. It is a very easy language to learn for those who have a software background, but it is not a language for those who do not have a software background. The expected learning period for ABAP is 6 months at the most. Under normal circumstances, this period is 1 month for someone with a software background. the period of specialization can be determined as 3-4 years on average. however, some consultants can become experts even in 1 year, while some consultants can still remain novice even after 10 years.
