hi,

see try this code.

TABLES sscrfields.

DATA flag(1) TYPE c.

SELECTION-SCREEN:

BEGIN OF SCREEN 500 AS WINDOW TITLE tit,

BEGIN OF LINE,

PUSHBUTTON 2(10) but1 USER-COMMAND cli1,

PUSHBUTTON 12(10) text-020 USER-COMMAND cli2,

END OF LINE,

BEGIN OF LINE,

PUSHBUTTON 2(10) but3 USER-COMMAND cli3,

PUSHBUTTON 12(10) text-040 USER-COMMAND cli4,

END OF LINE,

END OF SCREEN 500.

AT SELECTION-SCREEN.

MESSAGE i888(sabapdocu) WITH text-001 sscrfields-ucomm.

CASE sscrfields-ucomm.

WHEN 'CLI1'.

flag = '1'.

WHEN 'CLI2'.

flag = '2'.

WHEN 'CLI3'.

flag = '3'.

WHEN 'CLI4'.

flag = '4'.

ENDCASE.

START-OF-SELECTION.

tit = 'Four Buttons'.

but1 = 'Button 1'.

but3 = 'Button 3'.

CALL SELECTION-SCREEN 500 STARTING AT 10 10.

CASE flag.

WHEN '1'.

WRITE / 'Button 1 was clicked'.

WHEN '2'.

WRITE / 'Button 2 was clicked'.

WHEN '3'.

WRITE / 'Button 3 was clicked'.

WHEN '4'.

WRITE / 'Button 4 was clicked'.

WHEN OTHERS.

WRITE / 'No Button was clicked'.

ENDCASE.

hiii

for logic you need to add logic in PAI only.that is process after input..so after user enters value in textbox what logic should apply that will be there in PAI.for displaying purpose or like at selection screen if you want to maintein something then it will come in PBO event.

example

Hi

You need to write the logic in the PAI event of the selection-screen

so that after validation part is done you can process the values

Hi,

In Module Pool Program After User Interaction like Clicking Button is Handled By PAI Module.

So Double clicking the PAI Module you will go to the Screen Editor.there you Can write code for clicking pushbutton using

Case Sy-Ucomm.

For example you have a screen 100.

In the 'Element list' tab of the screen, give "ok_code" as the name where "OK" is the type of screen element. Activate screen.

The flow logic for the screen looks like this:

PROCESS BEFORE OUTPUT.

MODULE STATUS_0100.

PROCESS AFTER INPUT.

MODULE USER_COMMAND_0100.

Create the modules STATUS_0100 and USER_COMMAND_0100 in the main program by simply double clicking on them.

The code for these modules can be something like this:

MODULE status_0100 OUTPUT.

SET PF-STATUS 'Example'. "Example is the name of the GUI status

ENDMODULE.

MODULE user_command_0100 INPUT.

CASE ok_code.

WHEN 'SAVE'.

"call a subroutine to save the data or give statements to save data.

WHEN 'BACK'.

LEAVE TO SCREEN 0.

WHEN 'EXIT'.

LEAVE PROGRAM.

ENDCASE.

ENDMODULE.

Hi Hema,

pushbutton will act on user interaction so it be done in the PAI and in selection screen we have pai events like

AT SELECTION-SCREEN on field,

AT SELECTION-SCREEN on block and

AT SELECTION-SCREEN etc.

general we do all our validation part in this events.

and if you want to process something depending on the pushbutton and then display go for start of selection event...

With luck,

pritam.
