ABAP stands for Allgemeiner Berichts-Aufbereitungs-Prozessor. I know it's kind of difficult to understand. In Actual English term it's called Advance Business Application Programming. So what is this SAP ABAP all about?
The ABAP is a programming langauge which has been invented by SAP and is primarily used to develop custom functionality in SAP.
The ABAP programs run at the application server level, that is, both the applications provided by SAP and the ones you develop yourself. The ABAP programs read data from the database, process the data, and possibly store data.
ABAP programs are processed on the application server. The design of user dialogs and database accesses is of particular importance when writing application programs. The user is only interested in how his or her business transaction flows and how data can be entered and output within the transaction. The technical aspects of programming are less interesting for the user.
The user does not need to know the precise flow of the ABAP program on the application server. To the average user, the SAP System is like a "Black Box".
Technically speaking, however, there are three different types of screens: standard screens, selection screens, and lists. Each type of screen provides different services to the user. Here the task of the developer is to select for each user dialog exactly those types that are most suitable for the accomplishment of the tasks concerned.
Once the user performs a user action, for example by choosing Enter, a function key, a menu function, or a pushbutton, control is passed from the presentation server to the application server. Only certain parts of the ABAP program will then be processed. If a further user dialog is triggered from within the ABAP program, the system transmits the screen, and control is once again passed to the presentation server.
