dialog programming

[Former Member]

what type of function modules or formats or codings written in PBO and PAI for table control in dialog programming?

[Former Member]

Hi,

These are 2 events for designing the screens in module pool programing

PAI is used to write the code for the User actions on the screen.

Here data moves from screen to program.

PBO is used to display the fields from the program to the screen.

and we build the gui statuses in this PBO.

see the sample code

REPORT ZBHMOD1 .

DATA:OKCODE1 LIKE SY-UCOMM,

OKCODE2 LIKE SY-UCOMM.

DATA:N1(10) TYPE N,N2(10) TYPE N,RES(12) TYPE N.

MODULE USER_COMMAND_1000 INPUT.

CASE OKCODE1.

WHEN 'NEXT'.

RES = N1 + N2.

SET SCREEN 1001.

WHEN 'CLEA'.

CLEAR:N1,N2.

WHEN 'BACK'.

SET SCREEN '0'.

ENDCASE.

ENDMODULE. " USER_COMMAND_1000 INPUT

MODULE STATUS_1000 OUTPUT.

• SET PF-STATUS 'xxxxxxxx'.

SET TITLEBAR 'TIT1'.

ENDMODULE. " STATUS_1000 OUTPUT

MODULE USER_COMMAND_1001 INPUT.

CASE OKCODE2.

WHEN 'BACK'.

SET SCREEN 1000.

ENDCASE.

ENDMODULE. " USER_COMMAND_1001 INPUT

MODULE STATUS_1001 OUTPUT.

• SET PF-STATUS 'xxxxxxxx'.

SET TITLEBAR 'TIT2'.

ENDMODULE. " STATUS_1001 OUTPUT

Every Screen has a pbo and a pai.

Screen elements are the textbox, buttons, radio buttons and check boxes .....

If we want to pass data from a abap program to a screen element, we have to create a variable with the name we have given in the screen.So whatever the value is present in that variable is reflected on to the screen element.

Here is an example :

Using subscreens and some of the screen elements

REPORT demo_dynpro_subscreens.

DATA: ok_code TYPE sy-ucomm,

save_ok TYPE sy-ucomm.

DATA: number1(4) TYPE n VALUE '0110',

number2(4) TYPE n VALUE '0130',

field(10) TYPE c, field1(10) TYPE c, field2(10) TYPE c.

CALL SCREEN 100.

MODULE status_100 OUTPUT.

SET PF-STATUS 'SCREEN_100'.

ENDMODULE.

MODULE fill_0110 OUTPUT.

field = 'Eingabe 1'(001).

ENDMODULE.

MODULE fill_0120 OUTPUT.

field = field1.

ENDMODULE.

MODULE fill_0130 OUTPUT.

field = 'Eingabe 2'(002).

ENDMODULE.

MODULE fill_0140 OUTPUT.

field = field2.

ENDMODULE.

MODULE cancel INPUT.

LEAVE PROGRAM.

ENDMODULE.

MODULE save_ok INPUT.

save_ok = ok_code.

CLEAR ok_code.

ENDMODULE.

MODULE user_command_0110 INPUT.

IF save_ok = 'OK1'.

number1 = '0120'.

field1 = field.

CLEAR field.

ENDIF.

ENDMODULE.

MODULE user_command_0130 INPUT.

IF save_ok = 'OK2'.

number2 = '0140'.

field2 = field.

CLEAR field.

ENDIF.

ENDMODULE.

MODULE user_command_100 INPUT.

CASE save_ok.

WHEN 'SUB1'.

number1 = '0110'.

WHEN 'SUB2'.

number1 = '0120'.

CLEAR field1.

WHEN 'SUB3'.

number2 = '0130'.

WHEN 'SUB4'.

number2 = '0140'.

CLEAR field2.

ENDCASE.

ENDMODULE.

You can also check the transaction ABAPDOCU which gives you lot of sample programs.

Also you can see the below examples...

Go to se38 and give demodynpro and press F4.

YOu will get a list of demo module pool programs.

One more T-Code is ABAPDOCU.

YOu can find more examples there.

See the prgrams:

Hi,

In PBO and PAI, u have to code for reading and updating in the table control with the following loop.

LOOP WITH CONTROL TC_SER.

write ur code here.

ENDLOOP.

Hi,

PAI and PBO should be like this.

PROCESS BEFORE OUTPUT.

MODULE STATUS_1001.

LOOP AT ITAB WITH CONTROL TABC CURSOR TABC-TOP_LINE.

MODULE MOVE_DATA."this is for filling data in tab ctrl

ENDLOOP.

*

PROCESS AFTER INPUT.

MODULE USER_COMMAND_1001.

LOOP AT ITAB.

ENDLOOP.

HI Vennila,

Please see the sample code for module pool programming for table control...

process before output.

CODE TO BE WRITTEN IN THE FLOW LOGIC OF THE SCREEN ..........

module status_3000.

loop at g_tab_con_01_itab

into g_tab_con_01_wa

with control tab_con

cursor tab_con-current_line.

module tab_con_move.

endloop.

process after input.

module exit at exit-command.

module user_command_3000.

module clear_ok_code.

loop at g_tab_con_01_itab.

module read_tab_con.

endloop.

IN ABAP PROGRAM WRITE THE FOLLOWING CODES ..........

INCLUDE z_tab_ctrl_top

MODULE status_3000 OUTPUT.

SET PF-STATUS 'ST100'.

SET TITLEBAR 'T100'.

ENDMODULE.

MODULE update_table_control INPUT.

DESCRIBE TABLE g_tab_con_01_itab LINES tab_con-lines.

ENDMODULE.

MODULE exit INPUT.

ok_code = sy-ucomm.

IF ok_code EQ 'BACK' OR ok_code EQ 'EXIT' OR ok_code EQ 'CANCEL'.

LEAVE PROGRAM .

ENDIF.

ENDMODULE.

module clear_ok_code input.

clear ok_code.

endmodule.

module read_tab_con input.

*lines = sy-loopc.

READ TABLE g_tab_con_01_itab INTO g_tab_con_01_WA INDEX tab_con-current_line.

IF SY-SUBRC EQ 0.

MOVE-CORRESPONDING SFLIGHT TO g_tab_con_01_WA.

modify g_tab_con_01_itab from g_tab_con_01_WA index tab_con-current_line.

ELSE.

MOVE-CORRESPONDING SFLIGHT TO g_tab_con_01_WA.

APPEND g_tab_con_01_WA TO g_tab_con_01_itab.

ENDIF.

module tab_con_move output.

move-corresponding g_tab_con_01_WA to sflight.

endmodule.

module tab_con_get_lines output.

g_tab_con_01_lines = sy-loopc.

endmodule.

module tab_con_modify input.

move-corresponding sflight to g_tab_con_01_wa.

modify g_tab_con_01_itab

from g_tab_con_01_wa

index tab_con-current_line.

endmodule.

This will surely give you an idea of module pool programming using table control !

Reward if helpful !
