Online Programming:Exercises SAP Development ABAP Training

The following exercises are designed to help you understand online programming. Remember that anonline program can also be called a module pool program, a dialog program, or a transaction.

For many of the online programs you create, you will be using the YMO!"#O$% database table thatcontains &cademy &ward information. 'e created this table for the purpose of demonstrating onlineprogramming techni(ues. )eep in mind that the concepts you learn using the YMO!"#O$% table canbe applied to anyonline program using any&*&$ +ictionary tables-.

"ach of the exercises contains a testing section. This is nota comprehensie test plan. The (uestionsas/ed in this section for each program should be used to ma/e sure the basics in your program arefunctioning properly. !f you can thin/ of any other important testing conditions, feel free to list them.

Te sol!tions "or te programming section can #e "o!n$ in pac%age &'ABAP47TR(). !f you arehaing trouble figuring out how an online program should wor/, execute the solution online program.'ritten solutions can be found in your &*&$ manuals.

The purpose of this exercise is for you to create a simple online program to become familiar with thebasic components of an online program. &s you are creating this online program, try to identify eachcomponent you are creating4 screen attributes, screen layout, field attributes, flow logic, $*O modules,$&! modules, and global data.

This online program will act as an adding machine. On the initial screen 8111-, the user will enter twointegers. &fter pressing the 6"nter7 /ey, the user should be ta/en to the next screen 8113-.

On this second screen, the two integers from the first screen will be displayed along with the result of theaddition operation. These three fields should be display fields only i.e. the user should not be able toenter alues in these three fields-. &fter pressing the 6"nter7 /ey, the user should be ta/en bac/ to theinitial screen. The preious alues should be cleared out when the user returns to the initial screen.

&ll three integer fields should be eight bytes long.

&n example of these two screens can be seen on the next page.

+on7t forget you need to create a transaction code to execute this online program. *ecause you haenot learned how to code an exit in an online program, the easiest way to execute the program is to use a:o;tcode

This screen should use the JK! status 65"?OH+7 with the following function codes4 "!T, !H!T, andMO+!.

On this screen, the user will ultimately be able to insert or update a record with the 6Modify Record7pushbutton. You will not add this functionality to the 6MO+!7 function code until the next example.

The appearance of the screens will not change in this program. Ma/e sure that the 6"!T7 and 6!H!T7function codes on your JK! are defined as type 6"7 function codes.

To use the logical loc/ing mechanism, you can use the existing loc/ ob>ect 6"Q#MO!"7 or you cancreate your own. !f you create your own loc/ ob>ect, it should be named 6"Q#MO!"7 where 67 isthe last two digits of your logon id-. Remember that a loc/ ob>ect is an &*&$ +ictionary ob>ect.
