Development, Quality Assurance, and Production System
Objects are created or changed in the development system in this system group. The development work is tested in the quality assurance system, and transported to the production system after having been tested successfully.
This system group can be set up with the Standard Configuration function. The transport routes are generated automatically.
A consolidation route is created between the development system and quality assurance system with a transport layer.
The name of the transport layer is formed from the name of the development system ("integration system" from the transport perspective): Z<sid> (<sid> is the system ID of the development system)
A delivery route is created between the quality assurance system and the production system.
If you change objects in the development system whose development class refers to this transport layer, these changes are recorded in requests, which are transported to the quality assurance system and then to the production system.
If you change SAP objects, these changes are recorded in repairs, which can be transported in the same way.
