A question about value help

[Former Member]

Hello Expert,

I wrote one program as below:

Report  ZJWU_TEST3

parameters: p_A   radiobutton group gp1 default 'X',
                  p_B   radiobutton group gp1.

parameters: p_var type disvariant-variant.

at selection-screen on value-request for p_var.
  if p_A = 'X'.
    p_var = 'A'.
  else.
    p_var = 'B'.
  endif.

Now my question is, when I run the program and click the F4 help for p_var, the value of p_var is alway 'A' no matter what I select, p_A or p_B.  That is, the program will never go to "else" statement.

Can any one help to give some idea and let me know how to fix the issue?

Thanks in advance,

Regards,

Johnny.

Hi Yongbo,

Kindly modify your code as follows and you will get your expected result.

Report  ZJWU_TEST3

parameters: p_A   radiobutton group gp1 default 'X' USER-COMMAND fcode1 ,

                    p_B   radiobutton group gp1 .

parameters: p_var type disvariant-variant.

at selection-screen on value-request for p_var.

   if p_A = 'X'.

     p_var = 'A'.

   else.

     p_var = 'B'.

   endif.

Hiii,

         now check with F4.

parameters: p_A   radiobutton group gp1 default 'X' USER-COMMAND cmd,
                   p_B   radiobutton group gp1.

parameters: p_var type disvariant-variant.

at selection-screen on value-request for p_var.
   if p_A = 'X'.
     p_var = 'A'.
   else.
     p_var = 'B'.
   endif.

Even if you change it to Y or Z in the selection screen, the value will not be implicitly assigned to p_a in PAI. The default value X gets assigned to the screen field in PBO.

You have to look into the documentation of function DYNP_VALUES_UPDATE if you need a solution.
