INCLUDED in the landscape. DEVELOPMENT ---> QUALITY ----> PRODUCTION DEVELOPMENT : is where the the consultants do the

backwards.

Navigating a basic path The system functions can be called via the

tree structure or by entering TC-Transaction Coces

Every function in the SAPsystem is a TCode(Transaction Code)

/n ends the current transaction /o Opens a new session /I ends the current session

CLIENT CONCEPT client is a logical "subdivision" of the A data stored in a

SAP database. The client concept came from the timewhen several companies shared a single database onsome large central mainframe and obviously could not

be allowed to see each other's business data. Today the use of a client is different, e.g. it provides forseparation between customizing and sandbox clients ina development system, or between say test and trainingclients in a QA system.


27/30

client Technically all clients share the same set of tables. A

"client-dependent" table has the characteristic that itsfirst field (and the leading field of its primary key) isalways the client number. The "client-dependent"

attribute is maintained in the SAP dictionary. When an ABAP program contains a statement like "SELECT *FROM TAB" and TAB is client-dependent, the DBinterface in the kernel will automatically convert this to"SELECT * FROM TAB WHERE MANDT = "".

An SQL trace (ST05) of a simple business transactionwill reveal this behaviour immediately.


28/30

Not all tables are client-dependent, some arecross-client, i.e. their data is visible to andshared by all clients in the system. As a rule, allmaster/transaction tables are client-dependent,

while system tables containing instance-specificrather than business-specific data (e.g. the list ofprinters) are cross-client. Customizing tables aremostly client-dependent but some are cross-client (I'm a technical consultant so I can't reallytell you why that is).


29/30

CLIENT If one looks at a table at database level rather

than through SE16, one would see records forall clients residing in the same table. Incidentally

the same can be achieved in ABAP by addingthe CLIENT SPECIFIED option to the SELECTstatement but the code of business transactionsmust of course do no such thing.

The Change and Transport System (CTS) is a tool thathelps you to organize development projects in the ABAPWorkbench and in Customizing, and then transport thechanges between the SAP Systems in your system

landscape. This documentation gives you an overview of how youcan use the CTS to organize your changes, as well asbasic information on setting up your system and clientlandscape, and choosing a transport strategy. Read and

follow this documentation when planning yourdevelopment project.
