In a physical SAP system there can be multiple clients in each ofthe system of SAP system landscape.

A client has its own set user data.

Overview of Client

The main objective of the client is to eep the data isolatedAll the business management data is protected here because other clients can notaccess them. The data in a client can be only visible within that client; it can not

be displayed or changed from another client.

!ata in the R/3 are classi"ed as #lient$dependent % #lient$independent.When the SAP obects are ust used by only one client! those are defined as client

dependant data. "or e.g. #sers! $ustomizing etc. There are some obects asA%AP&' programs! which are used by all the clients in a SAP system. Thoseobects are called client independent data.

To (now whether a table is client dependant or independent you can search for afield MANDT. The client dependant tables always include the client field )*A+,T-as a part of the primary (ey.

A three di&it number identi"es a client."rom a technical viewpoint! this number is used as a (ey within tables thatcontain application data.

SAP comes with some pre$con"&ured clients.With a standard installation! SAP delivers 000! 001 and 066 clients which shouldnot be changed&deleted from the system.

$lient 000 is considered to be a SAP reference client and contains the clientindependent data of /&0. Special admin tas(s are performed here as user SAP1 or,,I$.

$lient 001 is a copy of client 222 with the difference being that the data is client

dependent. ,o not change any settings here. It should remain standard.


4/32

Overview of Client

After a new installation both 222 and 223 clients are identical! but after anupgrade 222 will have additional customizing data. 4ot of customer sites does notuse 223 client at all.

$lient 066 is there for SAP 5arly Watch service. This client enables SAP to

remotely access the customer system. SAP provides this service to the customerto improve the system performance. $lient 266 should not be changed or deletedfrom the system.

Apart from these 0 preconfigured clients! there could be some more clients fromSAP depending upon the Addon installed. "or e.g. if IS7I4 is being installed! all

the IS7I4 related activities are done through client 065.

$lient $opy is the mandatory first postinstallation steps for filling up the data innewly created $lients. Some imp notes before scheduling a client copyC

"or the stability of the system! always schedule the client copy in the

nighttime when the users are not wor(ing in the system.

To avoid data inconsistency the users should not (eep on wor(ing in thesource or target clients when the client copy is going on.

"or the best performance! always schedule the client copy in the

bac(ground.

The value of ma>imum online runtime parameter ma>EwpErunEtimeB inthe instance profile might need to be increased for a large client copy.

Proper authorizations is re8uired to run the client copy. As a basis systemadministrator you should have SAPEA44 profile to complete a client copysuccessfully. So SAP1 is recommended as it has all the authorizations neededby the client copy.

Always chec( the Tablespace usage F in database portion before 9 aftere>ecuting a client copy and also at the time of $lient $opy process.

The main memory plays a significant role in the client copy. *a(e sure thatyou have enough memory to finish the client copy without any problem.

If the client copy is loc(ed by another client copy run! then chec( the logbefore deleting the loc( entry in S*3? to remove the loc(.

The #lient #opy can be done in 3 ways

1. Local Client Copy: Gere the data is copied into new $lient from a clientwithin the same system.

2. emote Client Copy: In /emote copy the data is copied into the new clientfrom a /emote system.

!. Client Transport: ,ata can also be filled into the newly created client! fromanother system by way of (ransport Re+uest .
