Solved: Re: Dialogue programming

Former Member · ‎2008 Mar 25

Hi, I have never done this before but I am looking for an easy way to code a dialogue program. I need to be able to do drill down and add functional buttons. Are there any tutorials out there?

Thanks

Hi Michael Curtis,

Structure of a Dialog Program

A dialog program consists of the following basic components:

Screens (dynpros)

Each dialog in an SAP system is controlled by dynpros. A dynpro (DYnamic PROgram) consists of a screen and its flow logic and controls exactly one dialog step. The flow logic determines which processing takes place before displaying the screen (PBO-Process Before Output) and after receiving the entries the user made on the screen (PAI-Process After Input).

The screen layout fixed in the Screen Painter determines the positions of input/output fields, text fields, and graphical elements such as radio buttons and checkboxes. In addition, the Menu Painter allows to store menus, icons, pushbuttons, and function keys in one or more GUI statuses. Dynpros and GUI statuses refer to the ABAP/4 program that control the sequence of the dynpros and GUI statuses at runtime.

ABAP/4 module pool

Each dynpro refers to exactly one ABAP/4 dialog program. Such a dialog program is also called a module pool, since it consists of interactive modules. The flow logic of a dynpro contains calls of modules from the corresponding module pool. Interactive modules called at the PBO event are used to prepare the screen template in accordance to the context, for example by setting field contents or by suppressing fields from the display that are not needed. Interactive modules called at the PAI event are used to check the user input and to trigger appropriate dialog steps, such as the update task.

All dynpros to be called from within one transaction refer to a common module pool. The dynpros of a module pool are numbered. By default, the system stores for each dynpro the dynpro to be displayed next. This dynpro sequence or chain can be linear as well as cyclic. From within a dynpro chain, you can even call another dynpro chain and, after processing it, return to the original chain.

You'll probably find several through Google, but I'd start with the SAP help:

http://help.sap.com/saphelp_nw04/helpdata/en/9f/db9cdc35c111d1829f0000e829fbfe/frameset.htm

et al, and go from there... the transaction BIBS also gives some simple examples of screen layouts and the code behind them is basic... also, if you go to SE11 and do a "where used" on table SFLIGHTS you shouuld be able to find many of the demo programs that SAP provide, including dynpro / dialog ones.

You can check the tcode ABAPDOCU

Check the example programs under ABAP User Dialogs -- > Screens -- > Processing Screens
