What is an SAP
System Landscape?
An SAP system landscape refers to the arrangement of
SAP servers and environments that work together to support a business's ERP
processes. Each environment (Development, Quality Assurance, Production) plays
a specific role in the lifecycle of SAP applications.
Types of SAP
Landscapes
H4: 1. Single System Landscape
Used in demos or small projects. All development, testing, and operations
happen in one system.
H4: 2. Two-System Landscape
Consists of:
- Development
(DEV)
- Production
(PRD)
Used in small businesses, but lacks a dedicated testing environment.
H4: 3. Three-System Landscape (Most Common)
Includes:
- DEV
– Development system for coding, customizing
- QAS
– Quality/Testing system for validating changes
- PRD
– Production system for end-user operations
This landscape ensures proper version control, testing, and
transport management.
SAP Landscape
Architecture Overview
Core Layers in SAP
Architecture:
- Presentation
Layer: User interface (SAP GUI, Fiori, web browser)
- Application
Layer: Handles business logic and process execution
- Database
Layer: Stores all business data and metadata
This 3-tier architecture separates processing duties and ensures scalability, security, and performance optimization.

Key Components in
SAP Landscape Management
- SAP
Solution Manager – Central monitoring and system management
- Transport
Management System (TMS) – Controls movement of changes between systems
- System
Refresh and Cloning – Syncs environments by copying PRD to QAS or DEV
- Client
Strategy – Used for data segregation within the same system
- Landscape
Virtualization Management (LVM) – Manages SAP systems in virtual/cloud
environments
Best Practices for
SAP Landscape Configuration and Management
1. Standard Naming
Conventions
Use consistent system IDs (e.g., DEV, QAS, PRD) and client
numbers (e.g., 100, 200) across landscapes.
2. Effective
Transport Management
- Use
TMS to ensure proper release, import, and tracking of changes
- Avoid
direct changes in QAS or PRD
3. Proper User and
Role Segregation
- Separate
access by environment
- Assign
roles only in needed systems
4. Regular System
Refresh and Sync
- Periodically
refresh QAS from PRD
- Refresh
master data in DEV for realistic testing
5. System
Monitoring and Health Checks
Use tools like SAP Solution Manager, RZ20, and
ST06 to monitor health, availability, and performance.

✅ Top 30 SAP Landscape Configuration and Management Interview Questions and Answers
Q1. What is an SAP system landscape?
A: An SAP system landscape is a structured arrangement of SAP systems
used for developing, testing, and running business applications. It typically
includes Development (DEV), Quality Assurance (QAS), and Production (PRD)
environments.
Q2. What is the standard SAP 3-tier landscape
architecture?
A: The 3-tier architecture consists of:
- DEV
(Development system)
- QAS
(Quality Assurance/Testing system)
- PRD
(Production system)
Q3. Why do we use a separate QAS system?
A: QAS is used to test changes made in DEV before moving them to PRD,
helping prevent errors in the live environment.
Q4. What is the role of Transport Management System
(TMS)?
A: TMS handles the movement of development and configuration changes
between different systems (e.g., from DEV to QAS to PRD).
Q5. Which T-Code is used to configure the transport
domain?
A: STMS is used to configure and manage the transport domain.
Q6. What is a client in SAP?
A: A client is an independent environment within an SAP system that
holds its own data, users, and configuration.
Q7. What is the use of transaction SCC4?
A: SCC4 is used to maintain and define client settings, including change
permissions and roles.
Q8. What is client copy in SAP?
A: Client copy is the process of duplicating data from one client to
another, either within the same system (SCCL) or from a remote system (SCC9).
Q9. What is BDLS used for in system copies?
A: BDLS converts logical system names after a system refresh or client
copy, ensuring correct system integration.
Q10. What is the role of RZ10 and RZ11 in landscape
configuration?
A:
- RZ10
is used to maintain system profile parameters permanently.
- RZ11
is used to display/change parameters temporarily.
Q11. What is a logical system in SAP?
A: A logical system is an identifier used to differentiate between
different systems or clients in the same landscape.
Q12. What is a transport request?
A: A transport request (also known as a change request) contains
development or configuration changes that can be moved across systems.
Q13. What is STMS_IMPORT used for?
A: STMS_IMPORT is used to manually import transport requests into QAS or
PRD systems.

Q14. What is the function of transaction SE09 and SE10?
A: SE09 and SE10 are used to manage and view transport requests and
tasks.

Q18. What precautions should be taken before client copy?
A:
- Perform
full backup
- Inform
users and stakeholders
- Check
available resources
- Lock
clients to prevent changes

A: Using STMS_QA, where you can approve or reject transports
queued for QAS.
Q23. What are transport layers in SAP?
A: Transport layers define the path and behavior of transport requests
across landscapes, typically defined per development class.
Q24. What is the difference between a local and a remote
client copy?
A:
- Local
(SCCL): Copies data within the same system
- Remote
(SCC9): Copies data between different systems over RFC

A: It is an object (like a table or program) that is shared across all
clients in a system.
Q30. What are the benefits of using a 3-system landscape?
A:
- Better
control over changes
- Risk
