    hi

    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

    Hi,

    As per Standard SAP, following 3 Servers to be there;

    1. Development Development Server basically meant for all our developmental activities pertaining to configuration, development of existing programs, enhancement to the existing features in the available environment. Whatever we do first we create/change and test in development server, before put into action or transfer to other systems. These first creations will be done at development server level. For example if I want to create a GL account, I want to test the features of GL account and its functions in the development server ( box) and if I am satisfied with the performance I can transport this to other systems.

    Development server is an environment ( box) is a platform where you are creating all your configurations and test them thoroughly before making them productive. This is the first system/environment in SAP server architecture which I have shown in the bottom.

    2. Quality Quality environment is a second box and all the changes what we do first on Development server will be shifted to this box for further testing. The changes will be shifted from development server to quality server by transport management.

    Quality ensures testing by the users who requested for certain changes.

    3. Production Once the user tests the required changes and confirms their satisfaction in the quality server, then these changes will be transported

    to production environment.

    It is like this: Development Server ->Quality Server -> Production System

    Dear,

    There are three server.

    1) Golden client(100) : - If you want to some development for your transaction then is first came in golden client all confrigation is done golden client then it is transfer in all client development, quality and production.

    1) Development(110,190) : - After golden client all confriguation transfer in development. Business analist check all detail in this client. Then transfer it quality.

    3) Quality(200,210,220):- End user test data in quality. After development all data transfer in quality.

    4_) Production(300): - After quality all data transfer in production.

    All live work done in this server.

    Regards,

    Hi,

    Types of servers and its working applications can understand by the System Landscape . System landscape contains all systems( two System landscape or three System landscape or Four System landscape) that were installed. The customer can choose any landscape according to the requirements.

    If the customer is very big, one can implement four system landscapes. Mid size customers can go for two system landscape.

    The different system landscapes are :

    Four System Landscape:

    In this landscape, You will find four systems,

    1) Development system

    2) Test system

    3) Pre-Production system

    4) Production system

    Three System Landscape:

    In this landscape, You will find three systems,

    1) Development system

    2) Test system

    3)Production system

    Two System Landscape:

    In this landscape, we will find two systems,

    1) Development system ( You do dev. and testing)

    2)Production system

    Example: Three System Landscape

    In development system, we find three clients

    100

    150

    200

    100 can be used as configuration client. 150 can be used for development. 200 can be used for testing reference of configuration.

    The Test system contains two clients

    250

    300

    250 can be used for testing, where as 300 can be used for training purposes to endusers.

    The Production system contains two clients

    400

    450

    400 is the pre-production client which behaves exactly as production client. It contains data similar to production client. We can test with similar production data.

    450is the production client where the end users will be working with real time data supporting day to day business.

    Once you finish the configuration in Development Server according to your business requirement, all TRu2019s are transported to Quality Server and you can test here client business Process. If its working fine, then all TRu2019s are transported to Production Server from Development Server

    There are Three Servers In Standard SAP Namely Delvelopment, 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.

    A Typical Landscape Includes Four Servers Namely Development, Quality, Pre Production & Production.

    But, Its all Depends on Clients Business Processes & also Depends on Implementers.
