SAP ABAP (Advanced Business Application Programming) is a high-level programming language created by SAP for developing applications within the SAP environment. It serves as the backbone for building and customizing business applications in the SAP ERP system. ABAP is primarily used for developing programs that handle large amounts of data, generate reports, and perform complex calculations. It is integrated with SAP modules like FI (Financial Accounting), SD (Sales and Distribution), MM (Materials Management), and HR (Human Resources). ABAP provides tools for creating customized enhancements, developing forms, and building interfaces to integrate SAP with external systems. It supports both procedural and object-oriented programming, making it flexible for various business logic and workflows. As an integral part of SAP’s development framework, ABAP allows organizations to tailor SAP solutions to their specific business needs, ensuring better efficiency and performance across all processes.
