Data difference between System Copy and Remote Client Copy

[Former Member]

Hi,

Can you please let me know what is the data which we do not get in Target System when we do Remote Client Copy in compare to System Copy.

We want to have all data from our PRD System to QAS System and are under discussion what method we should use Remote Client Copy or System Copy.

I know we should use System Copy to get exact replica of PRD System but I need to know what data we are going to miss if we use Remote Client Copy.

Please suggest.

Regards,

Hi Shivam,

system copy usually can be a kind of migration of hardware change and the whole system was copied. system copy needs to export the data from source
system, then import the exported data to the new system during installation.

client copy is based on client, it almost the whole data of the client. When you are logging on SAP
you need to input a client number, that is the client. However an SAP system can have multiple clients.

Cheers,

Hi Shivam,

Client in SAP system: A client is organizational and legal entity in the SAP system. All the business management data is protected here because other clients can not access them. The main objective of the client is to keep the data isolated. Eg: user data, Transaction data, Master data.

Client independent data: All the repository objects, ABAP programs are common for all client.

Client copy - Local or Remote or export/import - all these will copy the client dependent data only, not the repository objects

System Copy - Exact copy of systems with all clients, client dependent data and along with the cross client data.

So, 1 - only the client specific data

2 - System copy (homogeneous or heterogeneous)

3 -  Cross client data.

Hello

Client copy does not copy cross client data that is:

1) Repository data (programs & dictionary)

2) Cross client customizing (but it is a very little subset of the whole customizing)

It also does not copy change documents.

All the rest (master data, transactional data, users, roles...) will/could (depending on the selected copy profile) be copied.

If you follow SAP standard for propagating changes

- create transport req. from dev to qual then prod

- do not perform cross client modification directly in qual

point 1 & 2 should not be an issue.

The main reason for choosing between client copy & system refresh is how long you can suspend activity on source system (batch & users).

You are not supposed to work (modify data) in the source (and target) system during the copy (tables are copied in alphabetical order and you modifications can spread over tables that are already copied & some that are not => inconsistencies).

For this reason there is a setting to lock the source & target client during a client copy.

The bigger your productive client is, the longer the copy will take.

You can shorten the client copy process by deleting target client before the copy (SCC5) as it is faster at to append data, than deleting + inserting.

If you have the ability to suspend activity on source system (batch & users) for a time that is long enough, then client copy is the easiest & quickest solution.

An other solution could be to perform a client export.

Hello

You just copy the data that belongs to the source system client to the target system client.

We want to have all data from our PRD System to QAS System and are under discussion what method we should use Remote Client Copy or System Copy.

Homogeneous System Copy

I know we should use System Copy to get exact replica of PRD System but I need to know what data we are going to miss if we use Remote Client Copy.

Imagine you have multiple clients on a system. In this case data is separated by clients.

A system will have client dependent data and client independent data.

When you do a client copy only the data that is part of one client is copied to the other client.

Eg: Tables like USR02 - Contains the user master records.

Hello,

You cannot copy master data(client independent data) from client copy. If you want to copy all data then you should perform system copy.

Thanks,
