WRITE issue to display

d4xtian — Sun, 21 Aug 2022 21:32:59 GMT

I wrote a program which calulate the third angle of a triangle after the user provide the First Two one.

I create a button to made the calculation, but it didn't display it...

how to forbid the user to put 0 on any field...of course the "Obligatory" do the job, but if it wasn't one how to do that.

and in the same time i put a button to leave the program even if the field are empty...

Thanks.

DATA: v_angle3    TYPE i,
      v_sum_angle TYPE i.


SELECTION-SCREEN BEGIN OF BLOCK blk1 WITH FRAME TITLE TEXT-001.

  PARAMETERS: p_angle1 TYPE i OBLIGATORY,
              p_angle2 TYPE i OBLIGATORY.
  SELECTION-SCREEN SKIP 2.
  SELECTION-SCREEN PUSHBUTTON 38(9) bt1 USER-COMMAND fc1.
  SELECTION-SCREEN PUSHBUTTON 26(9) bt2 USER-COMMAND fc2.
  SELECTION-SCREEN SKIP 2.
  SELECTION-SCREEN PUSHBUTTON 26(9) bt3 USER-COMMAND fc3.

SELECTION-SCREEN END OF BLOCK blk1.

INITIALIZATION.
  bt1 = 'Calculer'.
  bt2 = 'Reset'.
  bt3 = 'Sortir'.

AT SELECTION-SCREEN.

  CASE sy-ucomm.

    WHEN 'FC1'.

      v_sum_angle = p_angle1 + p_angle2.
      v_angle3 = 180 - v_sum_angle.


      IF p_angle1 > 178.
        message  'Number not allow' type 'E'.
      ELSE.
       write:  'L angle est de:',v_angle3 LEFT-JUSTIFIED,'degré' LEFT-JUSTIFIED.
      ENDIF.

    WHEN 'FC2'.

      CLEAR : p_angle1,
              p_angle2.

      MESSAGE 'Les Champs ont été effacés' TYPE 'I'.
    WHEN 'FC3'.

      LEAVE PROGRAM.

  ENDCASE.

Thanks you folks to read so far here you are a love...

Remove OBLIGATORY and do:

IF p_angle1 = 0.
  MESSAGE 'p_angle1 is obligatory' TYPE 'E'.
ENDIF.

You can modify your program as below:

This will smoothly gives message even though they enter 0.

  PARAMETERS: p_angle1 TYPE i ,     "Remove obligatory
              p_angle2 TYPE i .

In case section, add the wrapper IF statement as below

    WHEN 'FC1'.
     
     IF ( p_angle1 > 0 and p_angle2 > 0 )                "<=====Add a global if statement. 

      v_sum_angle = p_angle1 + p_angle2.
      v_angle3 = 180 - v_sum_angle.

      IF p_angle1 > 178.
        message  'Number not allow' type 'E'.
      ELSE.
       write:  'L angle est de:',v_angle3 LEFT-JUSTIFIED,'degré' LEFT-JUSTIFIED.
      ENDIF.
    ELSE.                                               "<=====Add a global if statement. 
      message  'Check your input' type 'S'.
    ENDIF.                                              "<=====Add a global if statement.

fotso

Write will be displayed after completion of the program.

So use message statement.

I have another question about the following:

message  'Check your input' type 'S' DISPLAY LIKE 'S'

Why use "DISPLAY LIKE 'S' " in this case as TYPE is already 'S' ?

I know that the difference is the type of icon which ll display ?

Thanks

🙂 Display like is optional. Not necessary.. I removed it.

It could help newbie..

This is how you display message with parameters

message i002(ZPOANGLE) with v_angle3.

Before you need to create a Message Class, by going to T-code SE91 Message Maintenance
