I can no longer organize my drop down book mark list ,from the toolbar in alphabetical order like I used to Why ?

Used to, I could organize my drop down book mark list from the tool bar, in alphabetical order from A-Z by clicking on view, sort by, select . Now every time I add a new bookmark it goes to the bottom of my bookmark list in Unsorted bookmarks . I can go to the bookmarks and sort the menu in Alpha. order. However, when I go back and drop down the bookmark list from the tool bar, the new bookmarks are still in the Unsorted list at the bottom. The bookmark's menu may or not have them in assorted list. This occurred several updates back. Why can I no longer sort the drop down book marks list in A-Z alph. order? This is a major obstacle when trying to search for a particular bookmark that I have made in the not too distant past.

That did solve my problem. Madperson Thank You Very Much!!!!! I'm not real literate on the mechanics of working computers even though I use them all the time. Basically I'm a point & click kinda guy and beyond that I'm pure novice! This is going to save me a lot of wasted time.

On updating from FF3.5.10 (good :-) to FF3.6.6 (bad :-( ): No session-restore option; no menu drop-down "Recently bookmarked" list. (Sys=winXP sp3)
1. can a non-techy fix this? :-(
2. how do I recover to FF3.5.10? - I liked it very much ! - thanks to all at Mozilla :-)

Make sure that you not run Firefox in [[Private Browsing]] mode.

How does one come to know this..drop down in ALV in WD

Hello Friends,
                      I had a requirement of adding a drop down in ALV, i eventually got it but I have some questions about it
I used the following code and got the drop down
lr_column = lr_column_settings->get_column( 'BWART' ).
CREATE OBJECT lr_input_field
    EXPORTING
      value_fieldname = 'BWART'.
lr_column->set_cell_editor( lr_input_field ).
DATA : LR_DROPDOWN TYPE REF TO CL_SALV_WD_UIE_DROPDOWN_BY_KEY.
CREATE OBJECT LR_DROPDOWN EXPORTING SELECTED_KEY_FIELDNAME = 'BWART'.
LR_COLUMN->SET_CELL_EDITOR( LR_DROPDOWN ).
DATA: LT_VALUESET TYPE TABLE OF WDR_CONTEXT_ATTR_VALUE,
LS_VALUESET TYPE WDR_CONTEXT_ATTR_VALUE,
LR_NODE TYPE REF TO IF_WD_CONTEXT_NODE,
LR_NODEINFO TYPE REF TO IF_WD_CONTEXT_NODE_INFO.
LR_NODE = WD_CONTEXT->GET_CHILD_NODE( 'RETURN_NODE' ).
LR_NODEINFO = LR_NODE->GET_NODE_INFO( ).
LS_VALUESET-VALUE = '973'.
LS_VALUESET-TEXT = '973'.
APPEND LS_VALUESET TO LT_VALUESET.
LS_VALUESET-VALUE = '222'.
LS_VALUESET-TEXT = '222'.
APPEND LS_VALUESET TO LT_VALUESET.
LR_NODEINFO->SET_ATTRIBUTE_VALUE_SET( EXPORTING NAME = 'BWART' VALUE_SET = LT_VALUESET ).
My question is ... how does 1 know which class to use? how to use that class... most of concepts about OOPS are clear.. but i still cant figure out how does 1 find out which class to use.. is it all by expericence..

In short: Yes, by experience. Then again, for WD4A there is a class for each UI-Element available. Once you know this, you can easily search se24 for CLWD<UI-NAME>* or the like.

Drop-downs in ALV: display list of code & value

Hi All.
When you define a Drop-down in Screen-editor (SE51) you'll get a field that contains list of code & value (if you set the "Show key within dropdown lists" option in the SAPGUI).
I would like to see the same behaviour in ALV Drop-downs. Currently there are 2 options: create a list that shows codes only, or create a that shows the values and the codes are hidden.
Both these options are set via the tables in Method "SET_DROP_DOWN_TABLE" of the CL_GUI_ALV_GRID class ([this is an example of how to set it|List Box in ALV Grid;).
Any idea how to set it will be welcome and rewarded.
Regards.

Hi Ridhima,
I need a drop down field in ALV list for my ABAP report. The user will select one of them and the report will go with this selection. How do you make such thing? I need it too..

Hi Shashi,
Your code looks okay. Debug & check if everything goes fine and all the required list of values getting bound to node.
Is any code after this logic, which sets data to table ? if so, that logic is wiping out the drop down list values from context node.
Final check point:
Read the context node 'TABLE' and fetch records into internal table in WDDOMODIFYVIEW( ) method to make sure that, every row of your table contains the drop down list entries in "LEAVE_VALUES" attribute
Hope this helps you.

Rama

Drop Down in ALV ABAP and NOT in OO - ABAP

Hello Everyone....
I m workin on an ALV which is in simple ABAP and not in OO-ABAP. There is some selection criteria on the first screen , as soon as the user fulfills the requirement an ALV GRID is displayed in which the last column is editable.
But the Problem is that i wanna make that editable field in ALV as drop down which would contain values from the database table.
Suggest me some method , so that i dont have to do much changes in my code .
A Sample code will be very benificial .
Thanx n Regards,
Harpreet.

Hi Harpreet,
[compiled from sap online help - always a good chice]
To make an input/output field into a list box, you must set the value L or LISTBOX in the Dropdown attribute in the Screen Painter. The visLg attribute determines the output width of the list box and the field. You can assign a function code to a list box field. In this case, the PAI event is triggered as soon as the user chooses a value from the list, and the function code is placed in the SY-UCOMM and OK_CODE fields. If you do not assign a function code, the PAI event must be triggered in the usual way that is, when the user chooses a pushbutton or an element from the GUI status.
If you have assigned a list box to an input/output field, you can use the Value list attribute of the screen element to determine how the value list should be compiled. There are two options:
Value list from input help (recommended)
If you do not enter anything in the value list attribute, the text field uses the first column displayed in the input help assigned to the screen field. The input help can be defined in the ABAP Dictionary, the screen, or a POV dialog module. It should be laid out in two columns. The key is automatically filled.
Value list from PBO modules (not recommended).
If you enter A in the value list attribute, you must fill the value list yourself before the screen is sent (for example, in the PBO event) using the function module VRM_SET_VALUES. When you do this, you must pass an internal table with the type VRM_VALUES to the import parameter VALUES of the function module. VRM_VALUES belongs to the type group VRM. The line type is a structure consisting of the two text fields KEY (length 40) and TEXT (length 80). In the table, you can combine possible user entries from the KEY field with any texts from the TEXT component. You specify the corresponding input/output field in the import parameter ID.

ENDMODULE.
The next screen (statically defined) for screen 100 is 100. The only input field on the screen is the component SDYN_CONN-CARRID. Its Dropdown attribute is set to L, and it has the output length 20. The Value list attribute is empty, and it has the function code SELECTED. The function codes of the buttons EXECUTE and CANCEL. CANCEL are defined in the GUI status as having the function type E.
The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
MODULE status_0100.
PROCESS AFTER INPUT.
MODULE cancel AT EXIT-COMMAND.
MODULE user_command_0100.
PROCESS ON VALUE-REQUEST.
FIELD sdyn_conn-carrid MODULE create_dropdown_box.
Users cannot enter any values into the screen fields. When they choose the input field on screen 100, the system displays a list box. The Value list attribute is empty, so the system launches the input mechanism. In this case, the event block PROCESS ON VALUE-REQUEST is created in the screen flow logic. This event block controls all other mechanisms. A two-column internal table is filled in the appropriate dialog module and passed to the input help using the F4IF_INT_TABLE_VALUE_REQUEST function module. The system inserts the two columns of the table into the list box.
When the user chooses a line in the list box, the PAI event is triggered using the function code SELECTED and the value in the first column of the internal table is copied to the input field.

Clemens

Check box and Drop down in ALV

Abt Drop Down For ALV Data cells

Hi,
I m unable to create drop down for each cell of ALV table.
Reply me as soon as possible.
Thks.

You need to create an object of type CL_SALV_WD_UIE_DROPDOWN_BY_KEY, which is the UI element for dropdown by key, and set that to be your individual cell editor.
For whichever column you want a dropdown box, use the method set_cell_editor to make the editor as a dropdown box. Hope this helps.

Drop down in ALV for Webdynpro ABAP

Hi Experts,
I was trying to implement one Web dynpro ABAP application that will show one ALV and ALV will content one dropdown so that user can select data from the drop down. Addtion to that, my dropdown should have data based on another column of ALV.
I have followed one article which is available in Net.
At the end of development, ALV is displayed with dropdown. Also dropdown has data binded. However, no data is visible in dropdown.
I have created one context node having four dictionary element and one elemt for dispplaying the dropdown.
In the DoInit method of view, i have written below code:
Data Declaration
DATA:
        lo_node_cskt TYPE REF TO if_wd_context_node,
        lo_el_cskt    TYPE REF TO if_wd_context_element,

    CLEAR ls_cskt-ktext.
    DO 3 TIMES.
      lv_count = lv_count + 1.
      CONCATENATE 'TEST' lv_count INTO ls_value_set-text.
      CONCATENATE 'TEST' lv_count INTO ls_value_set-value.
      if lv_tabix = 2.
       if sy-index = 2.
         EXIT.
       endif.
      endif.
      APPEND ls_value_set TO ls_cskt-valueset.
    ENDDO.
    MODIFY lt_cskt FROM ls_cskt INDEX lv_tabix TRANSPORTING ktext valueset.
ENDLOOP.

I am still finding the answer why data in drop down is not visible. However, I can select by clicking dropdown and blank elements (since data is not visible) can be selected.

Hey
i am using the same code except i have just modified little bit the select statement to restrict the number of entries.
and also besides writing the code in wddoinit i have added the compenent usage of alv component and added the node
having the structure ckst and after that deleting the dictionary reference to add the attribute valueset in both places
component controller and view controller and mapped them and mapped the data node of interface controller of comp
usage to this node in comp contrlr.
and adding the view container and embeding table view of alv comp there.
that's it
and here is the code which is almost same as yours except small change in select statement.
method WDDOINIT .

lo_node_cskt TYPE REF TO if_wd_context_node,
lo_el_cskt TYPE REF TO if_wd_context_element,

Down loading ALV List to local file /print

hi ,
We have a program that displays data on an ALV list. Then, when you click on the 'Print' icon, or try to download to a local file, it gives a short dump with a message 'OBJECTS_NOT_CHARLIKE'.
Any solutions on the same ....
thanks

Hi,
i hope you have all your data in and internal table.
If this is so use the following code,
*--- Down load the file
CALL FUNCTION 'WS_DOWNLOAD'
EXPORTING
filename = lv_file
filetype = 'DAT'
TABLES
data_tab = gt_excel1
EXCEPTIONS
file_open_error = 1
file_write_error = 2
invalid_filesize = 3
invalid_type = 4
no_batch = 5
unknown_error = 6
invalid_table_width = 7
gui_refuse_filetransfer = 8
customer_error = 9
OTHERS = 10.
IF sy-subrc = 0.
MESSAGE i000(zf) WITH text-017.
ELSE.
MESSAGE e939(zf) WITH lv_file. "Errors while downloading.
ENDIF.
Following should be passed,
v_file --> file path with file name (provide filename with '.xls' extension)
gt_excel --> Internal table which has to be downloaded to excel.
thanks

In FF4 there is no drop-down with a list of pages just visited as there was B4 for easy and quick return to a specific page.

It was located just to the right of the backward/forward buttons in the upper left of the screen. This was very convenient and allowed one to go directly to a past screen without having to click on the "back" button repeatedly until there.
If I am right and this has been eliminated, how can I replace FF4 with the previous version?
Thanks!

You can get the drop down list by either right-clicking on the back/forward buttons, or holding down the left button until the list appears.
If you want the drop-down arrow you can add it with the Back/forward dropmarker add-on - https://addons.mozilla.org/firefox/addon/backforward-dropmarker

Drop down like behavior list in a query

I would like to have drop-down list behaviour in a query. I could do it using with a UDF (U_TipoMat) with 2 valid values set in a user table.
DECLARE @TM Float
SET @TM=(SELECT T0.U_TipoMat FROM .[@PARAMETROS] TO WHERE T0.U_TipoMat = )
here it lets me select one of the 2 values stored in these UDF but it does not pass the value to the query
Any ideas?
Edited by: Héctor Ramón Santos Anaya on Mar 13, 2008 1:36 AM

Hector,
Can I know what is the end result you are trying to achieve.
What are you trying to do with the value in the variable @TM. Where are you planning to use this query?
Also [dbo\].[@PARAMETROS\] TO ...you have use TO instead of T0.
DECLARE @TM Float
SELECT @TM = T0.U_TipoMat FROM [dbo\].[@PARAMETROS\] TO WHERE T0.U_TipoMat = '[%1\]'

Adding a "blank" selection for drop-down menus under list items.

A lot of people on this form are accidentally selecting items that shouldn't be selected and need to be able to change the drop down menu back to blank if they have made a mistake and selected a wrong drop down item in the wrong area.
Please help,
Thanks!

Add an item to your Dropdown list with Blank as text and some value to it.
When you want to rest to blank, just simply set the rawValue to the value against the blank text.
For example if I add a blank text and assign a value "1" to it.
Then in the code I may use like below to rest it to Blank Text.
DropDown1.rawValue ="1";
Thanks
