SAP ABAP is a 4GL programming language used by SAP customers to enhance SAP applications, as well as create custom reports and interfaces. Creating ABAP programs requires programming skills, including knowledge of relational database design and preferably also of object-oriented programming concepts. SAP's newest development platform, NetWeaver, supports ABAP and Java. The ABAP language environment, including the syntax checking, code generation and runtime system, is part of the SAP Basis component.
