What is a R/3 Client?
R/3 Client is defined as an independent accountable business unit within a R/3 system.
R/3 Data Classification
Data in the R/3 database are classified as two types, Client Independent Data and Client Dependent Data.
Client independent data / Cross client data:
Data which can be accessed through the entire R/3 database from any client is called as client independent data or cross client data. Ex: screen data, transaction data, repository data and dictionary data.
Client dependent data / Client specific data:
Data which can be accessed through a client in which it was created is called as client dependent data or client specific data. Ex: user data, authorization data, application data.
As per above two types, the R/3 client maintains differentiation with respect to client dependent data. A number of clients are created in one R/3 database to maintain differentiation in customization, testing, quality assurance and production data.
A r/3 client can be identified with three digits numeric number starts from 000 to 999.
Customizing request(SE10)
Customizing requests contain changes to client-dependent tables.
Customizing request records client dependent objects like table entries, SPRO configurations. Client dependent objects are only available to a particular client.
SE01, SE09, and SE10 are the transaction codes for SAP Transport Management system.
Workbench request(SE09)
Workbench requests contain changes to client-independent tables.
Workbench request records client independent objects like reports, Functions, tables. Client independent objects are available across the system irrespective of a client.
Default SAP clients
After installation, there are three default clients configured in the database. Which are (for Non-Ides Software)
000 Master Client
001 Copy of master client
066 Early watch client
For IDES Software we have clients 800, 810, 812
Client 000 - Client 000 is a special client in SAP since it has client independent settings. Client 000 in SAP R/3 comes with a simple organizational structure. It is a sort of test company. Client 000 contains all standard configurations, parameters, standard transactions, etc that are normally used in the SAP R/3 business environment.
Client 001 - Client 001 is a copy of client 000. Client 001 also includes a test company. Client 001 can be customized to prepare it to move it into the production environment. However, once client 001 is customized, it does not behave like client 000.
Client 066 - Client 066 is used to perform "Early Watch" service for customer systems.
One important thing to remember is that during SAP R/3 implementation, once SAP is installed, the first thing to be done is copy a standard client included in SAP R/3 package. With the help of this, SAP users can start using SAP for creating tests, training, or even start using it for customization.

Login with user SAP*.
We need Logical System to create a client.
/nbd54 t-code is used for creating logical system then we go to se09 and Release.
Logical System
When data is distributed between different systems, each system within a network has to be clearly identifiable. The “logical system” deals with this issue.
A logical system is an application system in which the applications work together on a common data basis. In SAP terms, the logical system is a client.
Since the logical system name is used to identify a system uniquely within the network, two systems cannot have the same name if they are connected to each other as BW systems or as source systems, or if there are plans to connect them in any way.
SR047 lists names that cannot be given to BW systems, because they are reserved for internal use.
Logical system names must contain capital letters and numbers only. SAP recommends the following naming convention for logical system names: <System-ID>CLNT<Client>.

Release our logical system and come back to scc4

Release our logical system and come back to scc4
Then we press display change button(Ctrl+F4) After that we type New entries
Save and press back button that time we see our new client
Then we exit to log on screen give new client user name Sap* and password pass before we create a new user(/nsu01)
