Protecting Your Productive System
(Change & Transport System)
To protect the integrity and availability of your productive system, we recommend separating your productive system from your development system. We advise using at least two SAP Systems, and from a security point of view, we recommend three separate systems. With this landscape, you can thoroughly test your developments before making changes in your productive system.
The following topics pertain to protecting your productive system by separating your systems:
The Three-Tier System Landscape
The Common Transport Directory
Using the TMS Quality Assurance Approval Procedure
Configuring the System Landscape for Changes
Defining the Transport Process
Responsibilities and Their Corresponding Authorizations
Security for the RFC Connections
Protecting Security-Critical Objects
Protecting the System Profile Parameter Files
Protecting the Table for Maintaining System Clients (Table T000)
Protecting Other Security-Critical Objects
Emergency Changes in the Productive System
