hello guys, i am newbie in abap programming, i am trying to create simple arithmetic operation using selection-screen as a number input, but when i executed the programs, there was an error says : error when generating selection-screen, here's my code :

REPORT zt_aditya_latihan02 no standard page heading .

DATA : number1 TYPE i,

number2 TYPE i,

opp TYPE c,

result TYPE p DECIMALS 2.

SELECTION-SCREEN BEGIN OF BLOCK groupbox WITH FRAME TITLE text_201.

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN COMMENT 1(18) text_202 FOR FIELD p_a.

PARAMETERS p_a LIKE number1.

SELECTION-SCREEN COMMENT 1(18) text_203 FOR FIELD p_b.

PARAMETERS p_b LIKE number2.

SELECTION-SCREEN COMMENT 1(8) text_204 FOR FIELD p_c.

PARAMETERS p_c LIKE opp.

SELECTION-SCREEN END OF LINE.

SELECTION-SCREEN END OF BLOCK groupbox.

AT SELECTION-SCREEN OUTPUT.

text_201 = 'Angka Pertama'.

text_202 = 'Angka Kedua'.

text_203 = 'Aritmathic Operator'.

INITIALIZATION.

IF p_a = '' OR p_b = '' OR p_c = ''.

WRITE : 'all column must be filled'.

ELSEIF NOT ( p_c = '+' OR p_c = '-' OR p_c = '*' OR p_c = '/' ).

WRITE :'invalid operation input'.

ELSE.

CASE p_c.

WHEN '+'.

result = p_a + p_b.

WHEN '-'.

result = p_a - p_b.

WHEN '*'.

result = p_a * p_b.

WHEN '/'.

result = p_a / p_b.

WRITE : 'The Result of ', p_a , p_c, p_b , '=' , result.

ENDCASE.

ENDIF.

anyone kindly tell me what is my mistake? thanks

The problem is in the offsets of the comments

Try this way



SELECTION-SCREEN BEGIN OF LINE.
SELECTION-SCREEN COMMENT 1(18) text_202 FOR FIELD p_a.
PARAMETERS p_a LIKE number1.
*
SELECTION-SCREEN COMMENT 40(10) text_203 FOR FIELD p_b.
PARAMETERS p_b LIKE number2.
*
SELECTION-SCREEN COMMENT 70(8) text_204 FOR FIELD p_c.
PARAMETERS p_c LIKE opp.
SELECTION-SCREEN END OF LINE.

thanks for your reply, but it wont work that way, i found the solution

SELECTION-SCREEN BEGIN OF BLOCK groupbox2 WITH FRAME TITLE text_201.

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN COMMENT 1(18) text_202 FOR FIELD p_a.

PARAMETERS p_a like number1.

SELECTION-SCREEN END OF LINE.

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN COMMENT 1(18) text_203 FOR FIELD p_b .

PARAMETERS p_b like number2.

SELECTION-SCREEN END OF LINE.

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN COMMENT 1(18) text_204 FOR FIELD p_c .

PARAMETERS p_c LIKE opp.

SELECTION-SCREEN END OF LINE.

SELECTION-SCREEN END OF BLOCK groupbox2.
