How To Delete a Client

Step 1) T-code which is used for client deletion is SCC5.

Step 2) Click on "delete in background" to run client deletion as background job.You can also check option "Delete entry from T000" table.

Table "T000" contains clients' entry which we have created in SCC4.

Step 3) Check status of client deletion process using SM50.

Workprocess overview will open. "BGD" denotes background workprocess.

Once complete. Client will be deleted

Remote Client Copy:-

This technique uses Remote function call. You can view RFC from SM59. This technique depends on the network ,so network connectivity must be strong enough.

Scenario:-
Source Instance & client := BD1-101
Target Instance & client := DKM-202
Step 1) Log on to the target system. Here we will log on to DKM system. Create a new target client entry(202) using SCC4. Log on to this new target client with user SAP* and default password "pass".Here we will log on to DKM-200 system.

Step 2) Execute Transaction Code SCC9.

Step 3) Fill the basic details as per your requirement.

Step 4) Select Parallel Process.Parallel processes are used to exploit the capacity of database better.

Step 5) Schedule the client copy in background

Step 6) The client copy logs are available in SCC3 as given below.

Client Copy Pre-steps,Local Client Copy

Client Copy Pre-steps

To avoid data inconsistencies there are few pre-steps to be performed before starting client copy:-

1) Disconnect and lock business users(SU10).You can end the session of active users in the system through SM04. Once all users are logged out , check that no cancelled or pending update requests exists in the system.

2) Suspend all background jobs

Execute SE38 as given below.

Fill program name with "BTCTRNS1" as above figure.
Press Execute.

3) For a local copy , system must have enough space in the database or tablespace .
For remote copy, target system must have enough space in the database or tablespace. Check space using Tx DB02.

4) To avoid inconsistencies during client copy users should not be allowed to work in source client.

5) rdisp/max_wprun_time parameter should be changed to 2000 second as a SAP recommendation . Although you use parallel processes and schedule job in background , dialog processes will be used.

Local Client Copy

Local client copy is performed using Tcode SCCL.
Scenario:-

Source Instance & client := DKM-000
Target Instance & client := DKM-202

Step 1) Create an entry for your new target client using SCC4 . In our scenario, we will create client 202 in DKM system.Log on to this newly created target client (DKM-202) with user SAP* and default password pass.

Step 2) Excute T-code SCCL.

Step 3)

Select your desired profile
Enter Source client.
Enter Description

Step 4) By default Client Copy is executed as a single process. Single process will take a lot of time.We will distribute workload of single process to parallel(multiple) processes which will reduce time in copying a client.

Select Goto from menubar.
Select Parallel Process.Parallel processes are used to exploit the capacity of database better

Step 5) Always execute long running processes in background mode rather than foreground/dialog mode. Infact, some processes run more quickly in background.

Step 6) The client copy logs are available in SCC3 . Status - "Successfully Completed" means client copy is completed.

All About Client Copy – Local,Remote, Import/Export

Client Copy

We can generate a blank client with SCC4.But how to fill the data in the client ?"Answer is the client copy."

Client copy means "transferring client specific data" within same instance(SID) or between different instances(SID).

Client copy can be performed with three different methods -

Local client copy.
Remote client copy.
Client Import/Export.

Below brief details are given about client copy methods.

Local Client Copy :- This method is used to copy client within the same instance (SID).It is done by T-code SCCL.
