Keys to Understanding Versions …SAP versioning is a bit tricky – bear with it a bit until you learn it …It depends on which part of the stack you are asking about (application stack or technology stack) …It has evolved as SAP has changed its overall architecture from 2 tier to 3 tier …Many names are just marketing bundles of technology components

Overview

Main Concepts You Will Encounter …R/3, R/3 Enterprise, mySAP …ABAP …BASIS …WebAS …ECC …NetWeaver …Read on for explanations..

Application Editions … R/2

  Terminal server architecture   “Greenscreen” UI

… R/3

  Introduced client server architecture   Uses BASIS for technology stack   Desktop client UI

… R/3 Enterprise

  Replaced BASIS with WebAS (Web Application Server)   Web Based UI

… mySAP

  Web based UI   Changed “WebAS” to just “AS”

ABAP …Proprietary programming language …All of SAP was written in ABAP until about 3 years ago …ABAP doesn’t really have versions, it depends on the BASIS version being run

BASIS … R/3

  BASIS is the complete technology stack and application stack   Runs ABAP programs (all application logic is contained in the BASIS server)   BASIS acts as the application server using proprietary protocols to communicate to the desktop client   All changes to SAP application made in BASIS

… For R/3 Enterprise

  BASIS was split into BASIS and WebAS (WebAS uses standard internet protocols to communicate with web browsers)   BASIS version numbers aligned with WebAS versions   BASIS conceptually used only for administration (migrations, performance monitoring)

… For mySAP

  BASIS conceptually equal to WebAS

… Note: since the introduction of WebAS, BASIS versions are referred to either as both X.YZ and XYZ (e.g. 6.10 or 610, 7.0 or 700) where X.YZ is the WebAS version number

WebAS …Application server that replaced BASIS …Uses standard internet protocols so it can communicate with web browsers …Hosts ABAP engine (runs ABAP applications) …Version 6.20 had the first J2EE engine so you could write Java applications as well as ABAP

ECC (ERP Core Components) … Separates application logic from technology stack … All the modules you would buy (e.g. Payroll) are thought of now as in ECC (before they were thought of as in BASIS)

NetWeaver …This is just a bundling of standard technology stack components that are released together  WebAS  Enterprise Portal  Business Intelligence  Exchange Integraton

…WebAS renamed AS going forward

Try This View With What You Now Know In the beginning BASIS was both the server AND the application

BASIS sort of “sits in the middle” to help administer applications now
