What is mean by CLIENT?
Let us first understand what a client is before we move on to SAP client administration.
A client is defined as a self-contained commercial, organizational, and technical unit within an SAP System. This means that all business data within a client is protected from other clients. Each client has its own customer data, which can be considered as the exclusive property of this client.
However, the SAP System offers a system solution that is implemented for all clients in a central repository and cross-client tables (central data source).
As far as data administration is concerned, a multiple client option means that the data required for operating the system is well-defined and assigned either to central data or customer data. The following basic guidelines apply:
000 Client − This is called master client and is available when you install R/3 system.
001 Client − This client is a copy of 000 client including the test company. This client is used to create new clients normally.
066 Client − This is called SAP Early watch and is used for diagnostic scans and monitoring service in SAP system.

As far as data administration is concerned, a multiple client option means that the data required for operating the system is well-defined and assigned either to central data or customer data. The following basic guidelines apply:
- Only the assigned client can read or write to customer data, and in occasional cases (troubleshooting, background job administration, or change management) the provider. Customers can never read or write to the data of another customer.
- All clients can read the centrally stored data, however, only the provider can make changes, not any of the clients (end customers).
Advantages of Client Concept
Client concept comes in with the following advantages −- You can share the same resources between multiple users.
- You can manage SAP system landscape as you can create multiple clients for DEV, QA and PROD team.
- You can share your SAP system with a large number of users.
- You can create clients in SAP system from 000-999.
000 Client − This is called master client and is available when you install R/3 system.
001 Client − This client is a copy of 000 client including the test company. This client is used to create new clients normally.
066 Client − This is called SAP Early watch and is used for diagnostic scans and monitoring service in SAP system.
R/3 data can be divided into two categories:
- Client-Specific data is data affecting only one client, such as user master data and application data.
- Cross-client data is data affecting the whole system environment,such as cross-client customizing data and Repository objects.
