In most common client refreshment means re-reading data from the server to keep the data on the client up-to-date.

I'm not sure, is it what you are looking for? If not please explain yourself much clearly...

I've seen two kinds of "refresh" performed. A client refresh is used to copy data from one client to another, leaving the repository objects untouched. For example, in a standard 3-system landscape you may have the following clients:

DEV - 100 - Development

QAS - 100 - Integration Testing

PRD - 100 - Production

As testing is performed in QAS, the data becomes stale or "used up". At some point the testers would like to have the QAS client more representative of the production environment, so a "client copy" is performed from PRD-100 to QAS-100. This copies all the data from production back to QA. Of course, it won't copy DDIC information or ABAP programs (no repository objects), but just the data. This is usually done early in the project, before PRD gets very large.

As the systems grow, client copies become more difficult to perform; they are very slow with large data sets and often crash. Therefore, a "system copy" can be performed; this normally entails taking a backup of the PRD system and overwriting the entire QAS system with this backup. This has a coulple of advantages over a client copy:

1) very large databases can be quickly refreshed (multi-terrabyte)

2) repository information is copied as well (ABAP programs, data dictionary, etc)

While the client copy reads the source client data set row by row, inserting it into the target client, the system copy can be performed with technologies like split mirrors so that the "refresh" can be done in a matter of minutes or hours, rather than days.

Let me know if you need any more information about refreshes or how & why they're performed.

Hi guys,

I have seen a presentation of gold client. This is an excellent tool which utilizes and extends Sap client copy functionality.Using that tool you can copy Master and Configuration data using your selection criteria. This resaults smaller clients with limited data.
