Changing of default values on the selection screen dynamically

[Former Member]

Hi,

I have 2 radiobuttons R_A & R_B and i have one text field like P_TEXT. Based on selection of radio button i have to change the default values in P_TEXT on the selection screen. like if i select R_A i have to display P_TEXT = 'A'. if i select R_B then it has to display P_TEXT = 'B'. I tried like as below

in AT SELECTION-SCREEN OUPUT EVENT.

IF R_A = 'X'

P_TEXT = 'A'.

ELSEIF R_B= 'B'.

P_TEXT = 'B'.

ENDIF.

But it's not working. it is working only for first radio button. when i select second radio button it is not giving the second value. can any one tell the sol.

Tks in advance.

IF R_A = 'X'
   P_TEXT = 'A'.
* ELSEIF R_B= 'B'.  " Radiobutton value will never be "B"
ELSE. " If one radio button of the group is initial the other is set.
   P_TEXT = 'B'.
ENDIF.

Try it this way...

PARAMETERS: p_rb1 RADIOBUTTON GROUP rad1 DEFAULT 'X' USER-COMMAND abc,
            p_rb2 RADIOBUTTON GROUP rad1,
            p_text TYPE char10.

AT SELECTION-SCREEN OUTPUT.
  CASE 'X'.
    WHEN p_rb1.
      p_text = 'A'.
    WHEN p_rb2.
      p_text = 'B'.
  ENDCASE.

Hi Pammi,

Update your code as follows

parameters: r_1 radiobutton group g1 user-command US1,

r_2 radiobutton group g1.

parameters text_1(10) type c.

at selection-screen output.

if r_1 = 'X'.

text_1 = 'R1'.

elseif r_2 = 'X'.

text_1 = 'R2'.

endif.

This will solve your issue. User command needs to be added as when ever you click on the radiobutton the at selection-screen output will be called, else you will have to trigger an event by pressing the execute or any button. With the addition user-command US1 the event will be triggered as soon as you click on the radiobutton.

Hi Pammi,

Use this code, its working:-

PARAMETERS : r_a RADIOBUTTON GROUP gp1 DEFAULT 'X' USER-COMMAND rb,
             r_b RADIOBUTTON GROUP gp1,
             p_text(20).

"we use user command with the radiobutton so that some event is occured in order to call AT SELECTION-SCREEN OUTPUT.

AT SELECTION-SCREEN OUTPUT.

  IF r_a = 'X'.
    p_text = 'Hello'.
  ELSEIF r_b = 'X'.
    p_text = 'Hi'.
  ENDIF.

In the above case 'AT SELECTION-SCREEN OUTPUT' will act as PBO of the selection screen and will change value of selection text as per condition.

Hope this solves your problem.

Thanks & Regards,
