1.1 SAP System Landscape
The SAP System Landscape refers to the arrangement of SAP software and hardware components to support the efficient development, testing, and deployment of SAP solutions. The landscape includes various environments or systems that are interconnected to fulfill different purposes in the software development life cycle and business processes. Here are some key components of an SAP System Landscape:
1. Development System (DEV):
This is where SAP applications are developed and customized.
Developers use this system to create and modify programs, configurations, and other objects.
It is not used for actual business operations.
2. Quality Assurance System (QAS):
Also known as the testing system, it is used for testing and quality assurance purposes.
Testers verify the correctness of developments made in the development system before moving them to the production environment.
3. Production System (PRD):
This is the live environment where the actual business processes are executed.
It contains the data and configurations necessary for day-to-day operations.
4. Training System (TRN):
Used for training purposes to educate end-users on how to use the SAP system.
It may be a copy of the production system to provide a realistic training environment.
5. Sandbox System:
Sometimes organizations have a sandbox system for experimentation and learning.
It is isolated from the rest of the landscape and provides a safe environment for trying out configurations and developments without impacting other systems.
6. System Landscape Directory (SLD):
A central component that stores landscape information, system properties, and mapping information between different systems.
It helps manage system landscapes and enables smooth integration between systems.
7. Transport Management System (TMS):
Manages the transport of changes from the development system through the testing and quality assurance systems to the production system.
Ensures that changes are moved in a controlled and consistent manner.
8. Central User Administration (CUA):
In landscapes with multiple SAP systems, CUA is used to centralize the user administration, allowing user accounts to be managed centrally and propagated to other systems.
9. Disaster Recovery System:
Organizations often have a disaster recovery system to ensure business continuity in case of a system failure or disaster.
10. Integration with Other Systems:
The SAP landscape may need to integrate with other non-SAP systems or external services, and integration points are managed accordingly.
It's important to note that the specific components and the structure of an SAP System Landscape can vary based on the organization's requirements, size, and complexity. The landscape evolves over time to accommodate changes in business processes, technology, and organizational needs.
