Landscape is like a server system or like a layout of the
servers or some may even call it the architecture of the
servers viz. SAP is divided into three different lanscape
DEV, QAS and PROD.

- DEV would have multiple clients for ex: 190- Sandbox,
100- Golden, 180- Unit Test.
- QAS may again have mutiple clients for ex: 300-
Integration Test, 700 to 710 Training.
- PROD may have something like a 200 Production.

These names and numbers are the implementer's discreet on
how they want it or they have been using in their previous
implementations or how is the client's business scenario.

Now whatever you do in the Sandbox doesn't affect the other
servers or clients. Whenever you think you are satisfied
with your configuration and you think you can use it moving
forward, you RE-DO it in the golden client (remember, this
is a very neat and clean client and you cannot use it for
rough usage). As you re-do everything that you had thought
was important and usable, you get a transport request pop up
upon saving everytime. 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).

You don't run any transaction or even use the SAP Easy
Access screen on the 100 (golden) client. This is a
configuration only client. Now upon a successful tranport by
the Basis guy, you have all the configuration in the Testing
client, just as it is in the Golden client. The
configuration remains in sync between these two clients.

But in the Testing client you can not even access SPRO
(Display IMG) screen. It's a transaction only client where
you perform the unit test. Upon a satisfactory unit test,
you move the good configuration to the next SERVER (DEV).
The incorrect or unsatisfactory configuration is corrected
in Golden (may again as well be practised in the sandbox
prior to Golden) and accordingly transported back to 180
(Unit Test) until the unit test affected by that particular
config is satisfactory.

The Golden client remains the 'database' (if you wanna call
it that) or you may rather call it the 'ultimate' reference
client for all the good, complete and final configuration
that is being used in the implementation.

In summary:
Landscape : is the arrangement for the servers

IDES : is purely for education purpose and is NOT INCLUDED
in the landscape.

DEVELOPMENT ---> QUALITY ----> PRODUCTION

DEVELOPMENT : is where the the consultants do the
customization as per the company's requirement.

QUALITY : is where the core team members and other members
test the customization.

PRODUCTION : is where the live data of the company is recorded.

A request will flow from Dev->Qual->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
companies 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 develpoment is done is development client and the
request is transported to production.

These three are landscape of any Company. They organised
their office in these three way. Developer develop their
program in Development server and then transport it to test
server. In testing server tester check/test the program and
then transport it to Production Server. Later it will deploy
to client from production server.

Presentaion Server- Where SAP GUI have.
Application Server - Where SAP Installed.
Database Server - Where Database installed.
