hi,

just check these

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

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.

flow logic for screen 100

PROCESS BEFORE OUTPUT.

MODULE STATUS_100.

CALL SUBSCREEN: AREA1 INCLUDING SY-REPID NUMBER1,

AREA2 INCLUDING SY-REPID NUMBER2.

PROCESS AFTER INPUT.

MODULE CANCEL AT EXIT-COMMAND.

MODULE SAVE_OK.

CALL SUBSCREEN: AREA1,

AREA2.

MODULE USER_COMMAND_100.

Why do not you using Process on Value request(POV) event and use the Function Module F4IF_INT_TABLE_VALUE_REQUEST to select the data from the Database table and display on the field on the screen
