client settings in SAP

 System and Client Settings 
One-System Landscape
Each client has a different setting according to its role within the system. This setting can, however, vary due to the special requirements of a one-system landscape during the course of the project.
System Setting
The system change options define the customizing and development functions in an SAP System. These settings serve as a basis upon which the client settings are structured. Later in this document, you will find more detailed information on how the individual clients are set up.
For the one-system landscape, the system change options are set as follows:
System Settings in the One-System Landscape

SAP System	Options
Production system <PRD>	All objects (with Transport Organizer)

The system change option setting allows you to make any changes to all objects in the production system. This means that you must adhere strictly to the default configuration of the clients.PRD Client Settings
The client settings define the customizing and development functions in the SAP System. These settings do not override the system change options.
The following graphic displays a client in detail, using the customizing and development client 200 as an example:
(By default you cannot make changes to cross-client objects in this client as it is locked. The lock must only be removed temporarily for cross-client changes.)
Description of the Clients in the Production System PRD

• 000: SAP standard client

This client is used to set up new "neutral" clients by client copy. Do not change or delete this client.

• 001: SAP standard client

This client is used to set up new "neutral " clients by client copy.
Do not change or delete client 000 or client 001.

• 200: CUST: Customizing and development client

All changes are automatically recorded and stored in change requests in client CUST (200). This client is also used for developing programs. Cross-client customizing is only allowed in this client. You must not create any test data or carry out any tests.
At the end of this phase you must release all cross-client requests.
By default, changes to cross-client objects are prevented in this client by a lock. Only remove the lock temporarily for cross-client changes. You must remember that these changes directly affect all other clients.

• 210: SAND: "Sandbox" practice client

This client is used for getting to know the system, trying out applications or testing customizing functions. You can carry out client-specific customizing in this client. Changes are not recorded. Any changes that you make in this client and that you want to keep in your system have to be repeated manually in the client CUST (200). This client can be updated by the administrator at any time using a client copy from CUST (200).

• 300: QTST: Reference client for integration and training

This client has two uses. It is used to check the customizing and development changes before the integration test, and to set up the training client TRNG (310) before training, to ensure that all training sessions begin with the same conditions. In this client you cannot make changes to Repository objects or execute cross-client customizing. The function for changing client-specific objects is also deactivated in this client.

• 310: TRNG: Training client

This client is used for training the end user. This client contains master and transaction data to ensure that training is as realistic as possible. Neither development nor client-specific customizing is allowed. The function for changing client-specific objects is also deactivated in this client.
Setting TRNG using client copy leads to all master and transaction data being lost. Use Transaction SCC1 to transport change requests.

• 400: PROD: Production client

This is the production client for your company. You cannot execute any client-specific customizing settings, nor make any changes to Repository objects.

• 410: PPRD: Preproduction client

Integration testing is executed in this client. Testing can begin using master and transaction data that was transferred from the old system. In the preproduction client, you cannot make changes to Repository objects or execute cross-client customizing. The function that allows you to change client-specific objects is similarly deactivated.

• 066: Early Watch Client

This client is purely a service client that enables SAP to access remotely the customer system with regard to analyzing errors and performance. You must not change or delete this client.Client Settings in the Production System <PRD> (1)

Client Setup
The following graphic outlines the setup of clients by client copy or transports in this one-system landscape.

Client Setup in PRD
All clients in the production system <PRD> are set up after the system is installed by client copy from client 000.

The clients SAND (210) and TRNG (310) are also set up again, if necessary. The system administrator does this with client copy (Transaction SCCL ). For example, before the start of end user training, you can initialize the training client TRNG (310) again using a client copy of client QTST (300), so that each training session is brought up to an identical point.

The following table gives an overview:

Client Setup in <PRD> by the System Administrator Using Client Copy

SAP System	Source client	Target client	Reason	Time	Reference
<PRD>	CUST (200)	SAND (210)	Initial client setup	As needed	1
	QTST (300)	TRNG (310)	Initial client setup	As needed	2

The two clients QTST (300) and TRNG (310) are then also supplied with the customizing changes executed in client CUST (200). After each unit of work, each project worker who has made customizing changes copies those changes to both clients (Transaction SCC1 ).

Client Setup in <PRD> by Project Workers with Transport Requests

SAP System	Source client	Target client	Reason	Time	Reference
<PRD>	CUST (200)	QTST (300)	Customizing	As needed	A
		TRNG (310)	Customizing	As needed	B

The production client PROD (400) and the preproduction client PPRD (410) are set up after the system is installed by client copy from client 000.

The tested transport requests, the customizing changes and the developments from client CUST (200) are imported into client PPRD (410), as outlined in the table above. The integration test takes place in client PPRD (410). After completion of integration testing, the production client PROD (400) is also supplied with the transport requests from client CUST (200).

Do not delete any files in ...\TRANS\DATA or ...\TRANS\COFILE during the project phase. These files contain information and data for the import process.The tables below give another overview of transporting change requests in the one-system landscape. The system administrator performs the transports. If transports are to be made into the preproduction client PPRD (410), then the project manager has to release the requests. Transports into the production client PROD (400) are made after a successful integration test.

System and Client Settings in a Two-System Landscape
Each system has a specific role within the system landscape and there is a configuration for each role. As well, each client in a system has its own settings.
System Settings
The system change option settings defines the available Customizing and development functions in an SAP System. These settings are the basis on which the client settings are built. The following sections give you detailed information on the configuration of the individual clients.
If you own a Ready-to-Run system, the system change options for the development or production system are set according to the following tables. If you do not own a Ready-to-Run system, we recommend configuring your system according to these settings.
