F4 help for select options

[HarshalVakil]

Hi,

I have two select options. 1) iblnr 2) ivnum

also on selection screen I have two radio buttons 1) inventory 2) ware house

when user selects inventory radio btn it will only display iblnr field for input and hide ivnum and when user selects warehouse only ivnum is displayed and hides iblnr.

I am hiding one of this field for input using at selection screen output event.

I am also providing F4 help for both this fields using 'F4IF_INT_TABLE_VALUE_REQUEST' using at selection screen on value request event.

Now when i execute program and press F4 for iblnr or ivnum it will provide search help. but after getting search help if i cancel and select other radio button program is generating error.

basically the problem is after pressing F4 if i change radio button it will generate error.

how to solve this?

Thanks,

Harshal

Hi Harshal ,

The problem is with ur at selection-screen output event.

Change it to at selection screen.

You have declared radio button with default value x.

So in Before output its set as x.

So u r getting f4 help properly .

So After that if you select another radio button also its reading for first radio button only so you are getting error.

Please change it to AT SELECTION - SCREEN.

Hi Harshal

Is it working fine.

[Former Member]

Hi Harshal,

If you debug the code you will come to know that error is coming at below statement.

   l_dynprofield = gs_ret-fieldval.

In perform routine you are passing the values IBLNR to l_dynprofield.you should pass s_iblnr-low instead of iblnr. Please try this.

L_dynprofield contains IBLNR and as per the logic it will try to store gs_ret-fieldval value.

As you have not written any code for second radiobutton . you will not get any error for that. but you will get error for  r_im radiobutton.

Please try my solution once and let me know if you require any further help. grant some reward points if it helps.

Hi gaurav,

Thanks for the help.

What you have said is somewhat correct.

I have removed below lines from form.

    READ TABLE gt_ret INTO gs_ret INDEX 1.

    l_dynprofield = gs_ret-fieldval

and now its working perfectly..

thanks.

[HarshalVakil]

I haven't tried the thing you provided I have posted the solution in comment below.

BTW thanks for the help.

Still I will try your suggestion and let you know.

thanks

Hi Harshal,

If you give

If radio1 = x.

F4 help.

else.

f4 help.

endif.

Change it to seperate if condition.
