Overview of SAP


This article gives an overview of the SAP business platform. Most of the information here was found in the different articles on Wikipedia.

The big picture

R/3 ("R" = realtime, 3 = 3-tier architecture): This new architecture is compatible with multiple platforms and operating systems, such as Microsoft Windows or UNIX. This opened up SAP to a whole new customer base. Officially launched on 6 July 1992. Was renamed SAP ERP and later again renamed ECC (Enterprise Core Component)

SAP R/3 was arranged into distinct functional modules, covering the typical functions in place in an organization. The most widely used modules were Financials and Controlling (FICO), Human Resources (HR), Materials Management (MM), Sales & Distribution (SD), and Production Planning (PP).

SAP's Business Suite:

In addition:

ABAP = Advanced Business Application Programming; was originally used by developers to develop the SAP R/3 platform and by SAP customers to enhance SAP applications; Currently positioned, alongside the more recently introduced Java, as the language for programming the SAP Application Server, part of its NetWeaver platform for building business applications. The syntax of ABAP is somewhat similar to COBOL.

BASIS = Technological platform that supports the entire range of SAP applications, now typically implemented in the framework of the SAP Web Application Server; Can be seen as the virtual machine on which SAP applications run.

SAP ERP differs from R/3 mainly because it is based on SAP NetWeaver: core components can be implemented in ABAP and in Java and new functional areas are mostly no longer created as part of the previous ERP system, with closely interconnected constituents, but as self-contained components or even systems.
