hi Ranjitha,
Ensure that you are doing the following activities:
1-> in the field attributes, you have mentioned FCODE.
2-> use function module DYNP_VALUES_UPDATE to set the selected value to the field.
sample code:
put selected value into a dynpro field--
     IF dy_field-fieldvalue NE l_seark.
       REFRESH dy_field.
       APPEND dy_field.
       CALL FUNCTION 'DYNP_VALUES_UPDATE'
            EXPORTING
                 dyname               = sy-cprog
                 dynumb               = sy-dynnr
            TABLES
                 dynpfields           = dy_field
            EXCEPTIONS
                 invalid_abapworkarea = 1
                 invalid_request      = 2
                 no_fielddescription = 3
                 undefind_error       = 4
                 others               = 99.
Hope this helps,

Dropdown list in a module pool screen

Hi,
There are 2 radio buttons in module pool for 2 Plants.
Now another plant has to be added in the screen. The radio button has to be replaced with a drop down list for these 3 plants.
How can we acheive this?
Thanks,
Kumar.

Hi,
If u want a dropdown for the third plant you enter on the screen, You can use the FM 'VRM_SET_VALUES' to get the dropdown.
Just refer to this sample code to get a dropdown.
TYPE-POOLS: vrm.
PARAMETERS p_werks LIKE mseg-werks AS LISTBOX
VISIBLE LENGTH 20 OBLIGATORY.
DATA: t_werks TYPE vrm_values,
w_line LIKE LINE OF t_werks.
INITIALIZATION.
SELECT werks FROM mseg INTO table t_werks."(w_line-key, w_line-text).
*APPEND w_line TO t_carrid.
*ENDSELECT.
AT SELECTION-SCREEN OUTPUT.
CALL FUNCTION 'VRM_SET_VALUES'
EXPORTING
id = 'P_werks'
values = t_werks.
*END-OF-SELECTION.
WRITE: / 'Selected Carrid value:', p_werks.
Hope this is helpful.

Icon display in Module pool screen not visible to some users

Hi,
I have added an icon in one of the module pool screen with dynamic quick info. The page is rendered fine and the info is also displayed well for most users except some. I can't figure out why the icon is not being displayed for some users.
Do someone has any solution for this?
Thanks,
Sumith

As I recall, the icons are actually stored in a file on each PC so some users may have a corrupted or out-of-date file with the icons. You can look for posting on "how to add an icon" to see a discussion on this topic.
I found some useful info at:
Create and Add Icons to table ICON?

Problem with I/O field in module pool

hi experts,
        I am displaying some text in I/O field in module pool screen. I am giving the attributes of I/O field as "output only" type and no input. Initially the input was not enabled for it, only it should be in display mode. Once i click on 'CHANGE' pushbutton then only the input should be enabled and it should be in change mode.will u tell me how to do it programatically.

HI,
In PAI of that screen..
when the sy-ucom is 'Change' then use the Loop at screen--Endloop to modify the attributes value.
example..
LOOP AT screen
      CASE screen-name.
       WHEN 'Fieldname.
          screen-input = 0.
          screen-active = 0.
         MODIFY screen.
     ENDCASE.

Display Mode - Module Pool

Hi Friends,
Need help in Module Pool,
when button click want to display screen in Display Mode only.....

Hi Sharavan,
I hope you want to achieve the Toggle Display Functionality. To achieve this you have perform this following steps:
1. Define the names Properly for each of the individual Screen Elements. Like for Button you can do BTN_01.. etc etc...
2. In the PBO Module define a Module like MODULE screen_settings. In this you will run the following code:
LOOP AT SCREEN.
IF SCREEN-NAME = 'BTN_01'.
SCREEN-INPUT = 0.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
For a group of BTNs or Text Elements you can form a GROUP and can Enable and Disable all at once.
3. The Next step is the handling of the Table Control.In the PBO event there you will have the LOOPing the Table control.
There inside the loop place a Module and enable and disable each and individual rows.
You must keep a central Instance from where you can check whether you want the screen elements in DISPLAY/CHANGE mode.
Hope this will help.
Thanks,
Samantak.

Problem with DropDown List and ValueChange

Hi,
I have the following problem (I use NetBeans 6.1): I have a page, made with the Visual Web Designer, where there is a DropDown List component. The expected behaviour is once I select an item from the dropdown list, something (depending on the item I clicked) appears or happens (so, without any submit button or action link).
This is the code I have at the moment:
JSP (Pagina1.jsp):
<h:selectOneMenu binding="#{Pagina1.dataTypeDropDown}" id="dataTypeDropDown" immediate="true" onchange="return getSearchFields(this);" style="height: 24px; left: 192px; top: 24px; position: absolute; width: 744px" valueChangeListener="#{Pagina1.dataTypeDropDown_processValueChange}">
 <f:selectItems binding="#{Pagina1.dropdown1SelectItems}" id="dropdown1SelectItems" value="#{Pagina1.dropdown1DefaultItems}"/>
</h:selectOneMenu>
Bean (Pagina1.java):
public void dataTypeDropDown_processValueChange(ValueChangeEvent vce)
 String selectedValue = (String)vce.getNewValue();
 System.out.println(selectedValue); // nothing happens!
 System.out.println("Hello"); // nothing happens!
[...]My problem is that, whenever I select an item form the dropdown list, ehm... nothing happens.
What could I do? Isn't that a kind of "change of value"? JavaScript events work fine, but no way with the ValueChange.
And please consider that I'd like to obtain the same result with both Standard Components and Woodstock Components.
Any help would be greatly appreciated!
Thanks!

try adding "*this.form.submit();*" to your on change attribute of select menu.
Your on change will look like onchange="return getSearchFields(this);this.form.submit();"
This should work.

     WRITE / flightdate.
ENDSELECT.
CLEAR: wa_spfli-carrid.
This example switches to list processing during the screen processing for screen 100. Screen 100 has a single input field - the component CARRID from the ABAP Dictionary structure SDYN_CONN.
The flow logic of screen 100 is:
PROCESS BEFORE OUTPUT.
MODULE status_0100.
PROCESS AFTER INPUT.
MODULE cancel AT EXIT-COMMAND.
MODULE user_command_0100.
The PAI module user_command_0100 calls screen 500 using the CALL SCREEN statement. This screen encapsulates a basic list. It has the following flow logic:
PROCESS BEFORE OUTPUT.
MODULE call_list_500.
PROCESS AFTER INPUT.
The module call_list_500 defines the basic list and switches to list processing. Since the next screen after list processing is screen 0, screen 500 is a one-screen screen chain. After list processing, control returns to the position in user_command_0100 from which screen 500 was called.
If the user selects a line on the basic list, a detail list appears. This is achieved through the event block AT LINE-SELECTION. The program also contains event blocks for TOP-OF-PAGE and TOP-OF-PAGE DURING LINE-SELECTION, which define page headers for both the basic list and detail list.
Since there is only one list system in this program, there is no need for case distinctions within the list events.
With thanks & regards,
Sravani yendru.

Thanks ,

Hi,
Create a copy of PF-STATUS of the screen of the ALV grid which is displayed to your program.
Add the new button in the PF-STATUS.
Create a subroutine within your program.
In this subroutine SET PF-STATUS (copied pf-status).
Pass the form routine name for setting the copied PF-STATUS to the parameter I_CALLBACK_PF_STATUS_SET.
Create a new subroutine in your program to handle the oK_CODE for the new button.
Pass this subroutine name to the parameter I_CALLBACK_USER_COMMAND of the FM.
Pass the value of call back program (sy-repid) to the parameter I_CALLBACK_PROGRAM.

How to create dropdown list for custom remote function module

HI ,
       I created a custom remote function module for a ztable.table having four fields.But now the requirement is to maintain the dropdown list for input parameter .
For eg: I maintain Input parameter as action.For that Action we have to maintain a dropdown list(display,insert,update and delete values ) in function module.Is it possible.

Hi
Try using POPUP_GET_VALUES function module in the begining of the Function module this gives a POP to provide a value to you
In this you can provide a value
Check the import parameters of this Function module if it has COMBOBOX as parameter ( I dont have SAP access at this point of time) you can pass X to it so you get List box for the following fields
Create a domain to field and assing fixed values to it and use it in any table(As this works with only existing tables)
refresh fields.
DATA: fields LIKE SVAL OCCURS 0.
fields-tabname = 'MAKT'.
FILEDS-FIELDNAME = 'MAKTX'.
APPEND FIELDS.
CALL FUNCTION 'POPUP_GET_VALUES' " Try copying this in a Test program and execute
        EXPORTING
          POPUP_TITLE = 'Enter Mail Id here'
