Hi,

First design a screen. Transaction SE 80 -> Right Click on Programs -> Create a Program -> Choose type as Module Pool.

Within the program which will be typically named like SAPMZ<name> right click -> Create screen -> Go to Layout -> take three input/output fields and a pushbutton.

Double click on the pushbutton -> assign a function code (example 'ADD') .

Go to Element List -> enter 'ok_code' corresponding to the last entry (ok_code).

Activate.

In the TOP include define there global data types which will be of the screen field types.

e.g : DATA: number1 TYPE '<screenfield-number1>'

DATA: number2 TYPE '<screenfield-number2>'

DATA: result TYPE '<screenfield-result>'

In the PAI of the screen, write CASE: ok_code.

WHEN 'ADD'.

result = number1 + number2.

ENDCASE.

Activate the whole program.

When you click the push button the addition result should come.

Reward if Helpful.

Hi,

Firstly, you can go to Tcode SE80 and here create a package.

On that package name right click and select program.

Then choose program type modulepool program.

Similarly, you can create screen and then select layout and drag and drop labels and pushbuttons as per your requirements.. Then double click on th push buttons.You will see property window and there we will find FCTCODE and there type the names e.g suppose you want to

display then typy on the fctcode Display or any name as you wish.

After that save and activate it. and then close the window.

And then go back to the intial screen .

And then click Flow logic button and then uncomment the statement

module status_1000 PBO block and then doible click on status_1000

save and activate and then go back and then PAI block uncomment the statement module status_1000 and the dobule click on status_1000 and on that type the code below.

In the PAI of the screen, write CASE: sy-ucomm.

WHEN 'ADD'.

result = number1 + number2.

ENDCASE.

Activate the whole program.

When you click the push button the addition result should come.

If helpful then rewards me.
