Keys to Understanding Versions

SAP versioning is a bit tricky – bear with it a bit until you learn itIt 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 tierMany names are just marketing bundles of technology components


Overview


Main Concepts You Will Encounter

R/3, R/3 Enterprise, mySAPABAPBASISWebASECCNetWeaver

Read on for explanations..


Application Editions

R/2Terminal server architecture“Greenscreen” UI

R/3Introduced client server architectureUses BASIS for technology stackDesktop client UI

R/3 EnterpriseReplaced BASIS with WebAS (Web Application Server)Web Based UI

mySAPWeb based UIChanged “WebAS” to just “AS”


ABAP

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


BASIS

R/3BASIS is the complete technology stack and application stackRuns 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 clientAll changes to SAP application made in BASIS

For R/3 EnterpriseBASIS was split into BASIS and WebAS (WebAS uses standard internet protocols to communicate with web browsers)BASIS version numbers aligned with WebAS versionsBASIS conceptually used only for administration (migrations, performance monitoring)

For mySAPBASIS 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 BASISUses standard internet protocols so it can communicate with web browsersHosts 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 stackAll 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 renamed AS going forward


Try This View With What You Now Know

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

applications now

In the beginning BASIS was both the server AND the application
