SAP - What is Client? How to create a new client

 

What is a SAP Client?

Client = A Customer. 在SAP裡面，我們可以想成每一個customer 對應到一個client. 在一個SAP instance內, 可以創建一個或多個clients，而不需要安裝多套SAP軟體給每個客戶專用. 這提供了隔離，一個client 無法看到其他client的資料。  

What does client contain?

Application Data - Application data is the data that are stored in the database tables.

Customizing Data - Customizing data is data created by customers when they customize their systems

User Master Record - A user master record defines the authorizations assigned to a user. Basis consultants are responsible for maintaining the user master record and assigning authorizations.

SAP comes with three "standard clients": 

000 Client: We can find this clients in the system as soon as we install SAP r/3 software. This is called master client. Client 000 contains a simple organizational structure of a test company and includes parameters for all applications, standard settings, and configurations for the control of standard transactions and examples to be used in many different profiles of the business applications. It contains client independent data.

001 Client: This clients is a copy of the 000 client including the test company. This client's settings are client-independent if it is configured or customized. People normally use 001 clients to create a new client.

066 Client: This client is called early watch client. The SAP earlywatch alert is a diagnosis service, for solution monitoring of SAP and non-SAP systems in the SAP Solution Manager. Alert may contain Performance issue, average response time, current system load, Database administration,etc..
