Explain what is System Landscape

System Landscape:  Landscape is like a server system or like a layout of the servers or some may even call it the architecture of the server’s viz. SAP is divided into three different landscapes.

DEV (DEVELOPMENT SERVER) is where the consultants do the customization as per the company's requirement.

QAS (QUALITY SERVER) is where the core team members and other members test the customization

PROD (PRODUCTION SERVER) is where the live data of the company is recorded.

- DEV would have multiple clients for ex: 110- Sandbox, 100- Golden and 120- Unit Test.

- QAS may again have multiple clients for ex: 200- Integration Test, 210 to 230 Training.

- PROD may have something like a 300 Production.

These names and numbers are at the implementers discreet or at client's business scenario.

A request will flow from Dev->Quall->Prod and not backwards.

1. Sandbox server: In the initial stages of any implementation project, you are given a sandbox server where you do all the configuration/customization as per the company’s business process.

2. Development Server: - Once the BBP gets signed off, the configuration is done is development server and saved in workbench requests, to be transported to Production server.

3. Production Server: This is the last/ most refined client where the user will work after project GO LIVE. Any changes/ new development is done is development client and the request is transported to production.

Sandbox server is like a rough book and it doesn't affect the other servers or clients.

Golden Client is like a fair- note book in which you have to do the entire configuration once again. Whenever you think you are satisfied with your configuration and you think you can use it moving forward. As you re-do everything that you had thought was important and usable, you get a transport request pop up upon saving every time. You save it under a transport request and give your description to it. Thus the configuration is transported to the Unit Test client (180 in this example).  Golden Client as it is configuration only client, we don’t even don't run any transaction or even use the SAP Easy Access screen
