SAP Advanced Business Application Programming (ABAP)

SAP ABAP stands for Advanced Business Application Programming. SAP ABAP (Advanced Business Application Programming) is a high-level programming language created by the German software company SAP SE. ABAP is primarily used for developing and customizing applications within the SAP ecosystem, which includes enterprise resource planning (ERP) systems and other business software solutions. C++ is used to implement the ABAP kernel. A procedural and object-oriented programming model are both supported by the hybrid programming language ABAP.

Purpose of SAP ABAP

ABAP is designed to work with SAP’s software suite, allowing developers to create custom reports, enhancements, and applications that integrate with SAP systems.

It is used for developing both transactional and analytical applications, enabling businesses to manage their processes, data, and operations effectively.

SAP ABAP Architecture

It is known as R/3 Architecture, based on a client-server model.

SAP ABAP Architecture

It has 3 Layers:-

• Presentation Layer: – The presentation layer offers two mechanisms: Input, which lets users communicate with the system, and output, which lets the system show the results of human engagement. A graphical user interface is the SAP GUI. The SAP GUI is installed on individual machines that act as the presentation layer.
• Application Layer: It communicates by taking inputs from the Presentation layer manipulates the data according to business needs and takes data from the database layer then sends it back to Presentation Layer. It is the environment where all Business logic is written in the ABAP code environment.
• Database Layer: The data are stored in the database layer. Every relational database is supported by SAP. No database is provided by SAP. But it works with all RDBMS. One system or computer must have the database layer installed. Oracle and DB2 are the two main databases utilized in SAP deployments.
