|Before doing a client copy, you need to prepare the following :-
1. Find the source client space with the client size custom program
which can be implemented using the rel. note:
2. If your are on Unix OS, adjust all the file systems according to
PRD file system to fit the PRD client in DEV
3. You can do the client copy by remote or Export/Import
4. To speed up the export/import, use R3trans export/import for the
5. Do import and post processing.
Please refer OSS rel. notes for the few RZ10 parameters which needs to be set for cluster tables to speed up the process.
If it is a fresh installation, do this --
1. SCC4 --> Create client
no. and fill other details.
What are step and procedure to create a client & to take a client copy from source to target.
If you are copying from same system then flow the below steps:
1. Create the client in Tcode scc4.
If you are using different system then create a rfc connection in sm59.
Test the connection and then continue from the 1st step.
What is system refresh when and why it is done?
System refresh and client copy can be the same thing. Normally when you want to refresh a system this normally means refreshing the clients using a client copy like SCCL or SCC8.
A system "copy" is very different as this is far more involved than a simple "client refresh"
Imagine you have a DEV and a PRD system and after 6 months the data in DEV is very old so you would perform a client copy SCC8 from PRD to DEV using a profile that copies the application data from PRD to DEV - it actually deletes the data and replaces it with data from PRD. If however your DEV system died and needed to be completely rebuilt, you would use "Homogeneous System Copy" - you install the OS, Database and SAP and then process the system copy - which makes a complete copy of PRD (all clients)
Client copy - a single client refresh from PRD to DEV - can be just application data, or user data, or configuration or any combination you choose system copy - all clients 100% copied PRD to DEV
The system refersh is nothing but the deletion of the client and replacing the data from other client. For example : you have clients 100, 200 and 300. Suppose when you want to refresh the client 100 you remove the client 100 and replace it with 200 0r 300 as per your reqiurement. Mostly the refresh of clients will be happen at the time of development stage.
System Refresh is a simplified term to Client Copy. Client Copy means copying the production client on to the quality to test the real data. As recommend by SAP this need to carried out every 3 months.
The process to carry out the same is as follows:
