Table Control - Dropdown List

[Former Member]

Hi,

I have a Table Control Element on a Dynpro. Some colums are displayed as a Dropdown List (Listbox).

How can I put values into this listbox? I have looked at this thread http://scn.sap.com/thread/764416 and tried to use the FB F4IF_INT_TABLE_VALUE_REQUES. But it did not work. The Dropdown Box is still empty.

Every example I looked at, used a reference to DDIC Objects. But my table structure has no DDIC Referenz. I is defined in the report by TYPE statements. How can I build the DropDown List with a structure without any DDIC Reference?

Thank you very much in advance!

Best regards.

Hi Daniel,

Can you try this code?

Global Data Def.

DATA : GT_VALUES TYPE VRM_VALUES.

DATA : GS_VALUES LIKE LINE OF GT_VALUES.

in  PROCESS BEFORE OUTPUT.

loop at gc_control.

MODULE INIT_LISTBOX.

endloop.

           GS_APACT-TEXT  TO GS_VALUES-TEXT.

    APPEND GS_VALUES TO GT_VALUES.

  ENDLOOP.

  PERFORM VRM_SET_VALUES

Hi,

In the PBO create a module for the  listbox.Use the FM VRM_SET_VALUES to set initial values to list.

MODULE LISTBOX.

x_drop-KEY = '001'.

x_drop-TEXT = 'Test1'.

append  x_drop  to t_drop.

x_drop-KEY = '002'.

x_drop-TEXT = 'Test2'.

append  x_drop  to t_drop.

CALL FUNCTION 'VRM_SET_VALUES'

  EXPORTING

    id                    = 'X_TAB-TYPE'      --->Table Control fieldName

    values                = t_drop

EXCEPTIONS

   ID_ILLEGAL_NAME       = 1

   OTHERS                = 2.

ENDMODULE.

Hi!

Thanks for your reply!

Here are the properties of the table control and the field, which should get DropDown. I'm working in a German system, unfortunantelly se80 don't show me the english property labels even if I log in with english. Therefore I have translated the Properties by my own, hope you can see which one I mean.

Table Control TC_KRITERIEN

Type of Table:
X With Column Heading
X Configurable
No Title

Resizing:
X Vertical
X Horizontal

Separator:
X Vertical
X Horizontal

Row Markers:
Multiple

Column Markers:
No

With Marking Column:
WA_SEL_KRITERIEN-LFD_NR

Fixed Columns:
0

Input/Output Field for DropDown WA_SEL_KRITERIEN-QUELLSYSTEM
Dropdown: Listbox

FktCode: empty

Format: Char; No DDIC
No SET/GET Parameter

Inputfield: Yes
Outputfield: Yes

Input Assistance: Yes
Value List: Space (From Dict. / Flow Control)

Best regards,

Hi Daniel,

In the top include of the program declare internal table and workarea like this.

TYPES : BEGIN OF ty_value_tab,
          TEXT TYPE char100,
        END OF ty_value_tab.

DATA : return_tab TYPE STANDARD TABLE OF  ddshretval,
       t_itab     TYPE STANDARD TABLE OF ty_value_tab,
       x_itab     TYPE  ty_value_tab.

And in the flow logic of your screen write the code like this.

"New event

PROCESS ON VALUE-REQUEST.

FIELD LV_LIST MODULE f4_help_test.

"LV_LIST is a input field that we declared it in the layout.

"f4_help_test is a module that we are going to create in which we are going to write the logic.

Double click on the ""f4_help_test" and create a new module

Inside the module write code like .

  x_itab-TEXT  = 'alen'.
   APPEND x_itab TO t_itab.

   x_itab-TEXT  = 'lee'.
   APPEND x_itab TO t_itab.


   x_itab-TEXT  = 'mj'.
   APPEND x_itab TO t_itab.

   CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
   EXPORTING
     retfield        = 'LV_LIST'
     value_org       = 'S'
     dynprofield     = 'LV_LIST'
   TABLES
     value_tab       = t_itab
     return_tab      = return_tab
   EXCEPTIONS
     parameter_error = 1
     no_values_found = 2
     OTHERS          = 3.

"Hope this helps.

"Change the code according to requirement. I am saying about the internal table and all.
