Learn SAP-ABAP with Real Code Examples

Updated Nov 27, 2025

Explain

ABAP is used to develop programs, reports, interfaces, and forms in SAP ERP, S/4HANA, and other SAP solutions.

It allows manipulation of database tables, creation of business logic, and integration with SAP modules.

Supports modular programming through function modules, classes, and object-oriented ABAP.

Widely used in enterprise resource planning, supply chain, finance, and HR automation.

Programs can run on-premise or in SAP cloud environments (SAP NetWeaver, SAP HANA).
