data : v_status(10) type c.

data : begin of it_status1 occurs 0,

connid(8) type c,

end of it_status1.

RichHeilman · ‎07-13-2006

Please redefine like this and try again.



data : begin of it_status1 occurs 0,
       connid type char08,
       end of it_status1.

Also, you may want to adjust your function call like so. This will enable the value to be passed back to the dynpro field.



  call function 'F4IF_INT_TABLE_VALUE_REQUEST'
    exporting
<b>      DYNPROFIELD     = 'CONNID'
      retfield        = 'CONNID'
      DYNPNR          = sy-dynnr
      dynpprog        = sy-cprog</b>
      value_org       = 'S'
    tables
      value_tab       = it_status1
    exceptions
      parameter_error = 1
      no_values_found = 2
      others          = 3.

Do you want an F4 dropdown box, or a listbox?

If you are looking for a listbox, make sure that you set it as listbox in the screen. Go to the screen, click layout, double click field, in the dialog box, in the "Drop Down" field, choose "Listbox".

I am in need of just LIST BOX...

Former Member · ‎07-13-2006

in screen layout, i have defined the dropdown box perfectly..

I have given it as LISTBOX...

Former Member · ‎07-13-2006

Hi Pavan,

module create_dropdown_box input.

v_status = 'CREATE'.

append v_status to it_status1.

v_status = 'CHANGE'.

append v_status to it_status1.

v_status = 'DELETE'.

append v_status to it_status1.

clear it_status1.

In the above code , after filling the internal table with values, why are u using the statement

CLEAR it_status1.

I think it will clear the entire internal table.

Just remove that statement and try.

Regards,

SP.

Hi Pavan,

You said you are setting the value list attribute in the screen painter as listbox.. In that case, you cannot use this FM F4IF_INT_TABLE_VALUE_REQUEST.

You can use that FM only if you don't specify anything in the value list attribute.

If you are specifying it as LISTBOX , then you have to use VRM_SET_VALUES.

Just go through this link.

http://help.sap.com/saphelp_nw2004s/helpdata/en/9f/dbabe435c111d1829f0000e829fbfe/content.htm

Also check your internal table if it is containing any values in it.

Reward points if found useful.

Hi Pavan,

Dropdown box usually refers to a listbox. If you want to fill data in a listbox, first fill the internal table with all the values you want to display and pass the internal table to the Function Module VRM_SET_VALUES.

Just go through this link....

http://help.sap.com/saphelp_nw2004s/helpdata/en/9f/dbabe435c111d1829f0000e829fbfe/content.htm

If you want to fill value similar to pressing F4 on a field, then different technique is used.
