Normally, therefore, the target system is created using a copy of the production system. The advantages here are: After the initial setup, data is already available, and users receive a completely identical test environment.

An SAP system copy usually includes both the copy of the database and the copy of the file systems that contain the SAP system. There are several ways to create a system copy of an SAP system, depending on the type of database and operating system used.
The target system
In order to be able to work with the most up-to-date data possible on the development and quality assurance systems, it is necessary to bring an up-to-date production status onto these systems. This is often done via a complete system copy (production system -> development system, production system -> quality assurance system) and is very error-prone and user-intensive in ad-hoc configuration (especially if each developer/customizing user is responsible for saving the transports and importing them again after the copy). Every SAP system copy then carries the risk of losing the development status achieved and can lead to inconsistencies in programs and customizing, and any damage repair is usually very time-consuming.
