Client Administration

           Client Administration

When SAP is installed by default 3 clients (000,001,066) will be installed but in order to customize the system according to user requirements we need to create a new client.

Client will be copied from 000 client to enable customer based customizing

Table ooo- client table

USR02 – client dependent table because it consists of username, password and mandatory fields

Mandatory fields	B.Name	B.Code
066	Early watch	ABTRX (Encrypted password)
000	Sap*	-
000	DDIC	-
001	Sap*	-
001	DDIC	-

Two types of client data:

Client dependent date: User master record, customizing data (company code) and application data also called as customizing data

Client independent data:  Tables and reports also called as repository data.

In client copy and client transport tools the data will be replaced.  It is not designed to combine the data of different clients

How to create the new client -

Create a client:

1.  Go to SCC4

2.  New entries

3.  Client number

4.  Client name

5.  Location

6.  Currency

7.  Client role (eg: production, test, customizing, demo, training /education, Sap reference)

8.  Logical system Name:  it is identified by (<SID>CLNT <client number)

Eg:  DEV CLNT200

It is used to identify the client across the system/landscape.  Logical system can be created in SALE (system application linking enabling).  Transfer the data between loosely coupled systems

9.  Clients settings: ARC: Automatic recording changes

When we set a client with ARC, a change request will be generated whenever a change/create occurs in the client (customizing client is to be assigned to ARC)

10.  Changes to client dependent objects only

Changes to client independent objects allowed

11. Protection level (0 for no limit, 1 for no overwriting 2 no overwrite and no external availability). A client with protection 1 and 2 will not functions as target client

12. CATT (computer aided testing tool) is allowed. CATTs are used to generate test data which are used for demonstration purposes later

13.  Protection against copy/upgrade

Client Copies Types

There are three ways we can go for client copy

• Local client copy(SCCL)
• Remote client copy(SCC9)
• Client transport:  Client export and import(SCC8 and SCC7)

Prerequisites of client copy:

Ø  Find the size of the client (RSTABLE SIZE AND RSSPACE CHECK) by using SA38

Ø  Back ground process is available

Ø  No user are logged into the source client

Ø  Test run /simulation

Ø  Lock all the users in the source client.

Ø   Client copy must be started from the target system, so login into the target system using sap* and pass

Ø   Ensure that transport management system is configured and working fine.

Ø  Minimum two background jobs should be available, otherwise pause all background jobs by enter TC-SE38 and run RSBTCTRNS1 report. To reschedule all job back into normal run RSBTCTRNS2 report.

Ø   RDDIMPDP job should be run in background, otherwise run report RDDNEWPP.

Ø   TEMP and TRANS directories should be have three times of client size free space.

Procedure of client copy-

Local client copy:  when we copy the client in the same system we can use SCCL

• Logon to the target client with sap* and pass
• Go to SCCL, specify the profile (SAP_ALL, SAP_NEW)
• Select the client from where the data has to be copied
• Schedule the back ground
• GO to SCC3 to monitor the client copy logs
• Go to SM37 to find the background status

Remote client copy: 

• Create a client in SCC4
• Set up the client
• Login to the target client
• Establish a connection between a target client and source client in SM59
• Go to SCC9
• Select the profile
• Select the source client
• Execute in the background

Client Export and Import:

1 . Run SCC8 

2. Select Profile for desired copy type (Usually All SAP_ALL or user master only SAP_USER. You will need direction from the requester as to the correct selection here. Use Profile -> Display Profile to display profile details.) 

3. Select target System (or group)  4. De- Select “Test Run” (If selected)  5. Run Export  - Up to 3 requests are created, depending on the data selected and available:  1. “SIDKO00353" for transporting client-independent data, if you have selected this  2. “SIDKT00353" for transporting client-specific data  3. “SIDKX00353" for transporting client-specific texts, provided texts are available in this client  6.Monitor TP logs for errors and export files for growth
2. Login to client (sap* – pass) 
3. Manually add “O” transport then “X” then “T” to TMS buffer 
4. Highlight #1 and use “Request -> Import” to launch import tool 
5. Monitor “I” file in OS “/usr/sap/trans/tmp” dir for progress info 
6. After Import is complete perform “post processing steps” from client tool (SCC7)
