Editor's Notes
- #18: SAP R/3 Technical Configuration An SAP R/3 System can consist of one or more instances (e.g. a central instance or a distributed SAP R/3 System). Multiple instances are represented by the configuration of a database server and one or more application servers. Only one database and dictionary will exist for an SAP R/3 System. Note: with R/4, you can have multiple database instances. To isolate each distinct phase of an implementation, a typical or recommended configuration for an SAP R/3 System implementation will consist of three separate systems: Development: for configuration of SAP applications with user specific data and user development. Quality Assurance Testing: to isolate development from final testing and user training for production. Production: of live business transactions and company data.
