From the main menu, you can go to three conceptual areas in the R/3 system:
the Applications area
the Basis area
the Development Workbench
In the Applications area, you initiate transactions for the functional areas within R/3. To access these, from the R/3 main menu choose one of the following: Logistics, Accounting, Human Resources, or Information Systems.
In the Basis area, you can run transactions that monitor the R/3 system itself. To access the Basis area, from the main menu choose the menu path Tools->Administration. Here you will find many performance, tuning, and database administration tools.
The Development Workbench is used to create and test ABAP/4 programs. As an ABAP/4 programmer, you will spend most of your time within the Workbench. To access the Development Workbench, choose the menu path Tools->Development Workbench. However, your code will most probably read or update application data, and so it will be destined to become part of the application area. With that in mind, let's have a look within an Applications area first.
For our example, imagine that you are a clerk working in an accounts payable department. A vendor calls to say his address has changed. You put a bookmark in the magazine article you were reading (A Criminologist's View of the Problems with Creative Accounting) and proceed to update his address in the R/3 system. First, you reach the Accounts Payable menu by choosing the menu path Accounting->Financial Accounting->Accounts Payable.
You then bring up the vendor master record maintenance transaction by choosing the menu path Master Records->Change . You will see the Change Vendor: Initial screen.
From the Initial screen shown in Figure 1.7, you type his vendor number, tickmark the Address check box, and press the Enter key. You will then see the Address screen .
You change his address and press the Save button .
Saving changes to the vendor's address.
Upon saving, the system returns you to the Change Vendor: Initial Screen. It also displays a success message within the status bar located at the bottom of the screen .
The Initial Screen gives verification that the address change was made.
This transaction is representative of many of the transactions in the R/3 system. Most master data transactions have a similar look and feel.
