ABAP (Advanced Business Application Programming) is a high-level programming language developed by SAP SE for the creation of business applications. Primarily used within the SAP ecosystem, ABAP allows developers to create custom reports, interfaces, enhancements, and forms, all while ensuring a strong integration with the SAP database. This high-level language, being a fourth-generation programming language (4GL), is designed to be closer to human language, often requiring less code to accomplish tasks compared to traditional third-generation languages.
