1. Decision: Basic System Variants of SAP Web AS

SAP Web Application Server

Database Instance

SAP Web AS ABAP

ABAPSchema

For SAP Web AS 6.40, the following basic system variants exist:

• SAP Web AS ABAP(ABAP Engine, but no J2EE Engine)

•One infrastructure for ABAP•All kinds of ABAP applications•Database with ABAP schema

Detailed view: central instance consists of both ABAP and Java parts, SCS instance only required for Java

2. Decision: Distribution Options

SCS instance now always gets installed on the central instance host

So, only distribution option for one system is if you want to install a central system (CI + DB on one host) or a distributed system (CI and DB on different hosts)

Complexity reduced
