Hi ,
I think its not get updated because the external context mapping of the node is done at design time... so remove the design time mapping and do the dyanamic mapping .. once the attributes valueset is updated.. see the below code...
Instantiate ALV component
DATA: l_ref_cmp_usage TYPE REF TO if_wd_component_usage.
l_ref_cmp_usage = wd_this->wd_cpuse_alv( ).
IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
l_ref_cmp_usage->create_component( ).
ENDIF.
Pass context node to ALV
DATA: l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table .
l_ref_interfacecontroller = wd_this->wd_cpifc_alv( ).
l_ref_interfacecontroller->set_data( dyn_node ).
hope this will help ..............

Hi
In the transaction OAOR, you should be able to insert your company Logo.
GOTO - OAOR (Business Document Navigator)
Give Class Name - PICTURES Class Type - OT..... then Execute
It will show you the list, then select ENJOYSAP_LOGO.
On that list, you will find one control with a "create" tab.
Click std. doc types.
Select SCREEN and double-click.
It will push FILE selection screen.
Select your company logo (.gif) and press OK.
It will ask for a description- for instance: "company logo".
It will let you know your doc has been stored successfully.
You can find your logo under ENJOYSAP_LOGO->Screen->company logo.
Just run your ALV program, you should find your company logo in place of the EnjoySAP logo.
FORM TOP-OF-PAGE.
CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'
EXPORTING
IT_LIST_COMMENTARY = HEADING[]
I_LOGO = 'ENJOYSAP_LOGO'
I_END_OF_LIST_GRID ='GT_LIST_TOP_OF_PAGE'.
ENDFORM. "TOP-OF-PAGE
Here 'ENJOYSAP_LOGO' will replace by ur created logo.

F4 help for a dropdown field in ALV

I am trying to enable F4 help for a field in ALV (OO style) that also has a dropdown assigned to it.
If I enable the dropdown in the field catalog, the field does not respond to F4 event at all.
When I remove the dropdown attribute from the field catalog, the F4 help works, but obviously now there is no dropdown.
The reason I am trying to implement it this way is that my dropdown list (which is the same for all rows) is quite large while F4 help depends on the current line in the ALV (so the available values are limited).
I would like to try to avoid creating a dropdown handle for every row in ALV.
Does anybody know if it's even possible to have a dropdown and F4 help at the same time in ALV?

Hi
Linking F4 Help to Fields
For the last section, we will deal with linking F4 help to fields. It is easy. As usual, define, implement and register the event onf4 at proper places in your code. For F4 help, you must register the fields whose F4 request will trigger the onf4 event. For this you must prepare a table of type LVC_T_F4 and register this table using the method register_f4_for_fields. While preparing table you must include a line for each field which will trigger F4 event. For each field in the structure;
1) Pass the fieldname to FIELDNAME
2)Set REGISTER to make the field registered,
3)Set GETBEFORE to provide field content transport before F4 in editable mode
4)Set CHNGEAFTER to make the data changed after F4 in editable mode.
Preparing table for the fields to be registered to trigger F4 event
DATA: lt_f4 TYPE lvc_t_f4 WITH HEADER LINE .
lt_f4-fieldname = 'PRICE'.
lt_f4-register = 'X' .
lt_f4-getbefore = 'X' .
APPEND lt_f4 .
CALL METHOD gr_alvgrid->register_f4_for_fields
EXPORTING
it_f4 = lt_f4[] .
A sample onf4 method implementation
METHOD handle_on_f1 .
PERFORM f4_help USING e_fieldname es_row_no .
er_event_data->m_event_handled = 'X' .
ENDMETHOD .
Again, we set the attribute er_event_data->m_event_handled to prevent further processing of standard F4 help.

How to get selected-value of dropdown-field in alv ?

Hello experts,
I have a alv-table with dropdown-field.
When I open the dropdown I am able to select another value.
Now I use method ON_CLICK with ON_CELL_ACTION, and when
I change value in my alv, system jumps into this mehtod.
But how do I get now the selected dropdown value in this method ?
I use following code in comp-wdini in order to declare the dropdown:
Dropdownfield
DATA: lr_dp TYPE REF TO cl_salv_wd_uie_dropdown_by_key.
DATA: lr_node TYPE REF TO if_wd_context_node_info.
DATA: lt_valueset TYPE wdr_context_attr_value_list.
DATA: ls_valueset TYPE wdr_context_attr_value.
DATA : lr_nodeinfo TYPE REF TO if_wd_context_node_info.
DATA wa TYPE cdbc_tj30t.
DATA: lr_drdn_by_index TYPE REF TO cl_salv_wd_uie_dropdown_by_idx.
SELECT *   FROM cdbc_tj30t INTO wa WHERE stsma = 'CRMOPPOR' AND
    spras = 'DE'.
    ls_valueset-value = wa-estat. " actual values
    ls_valueset-text = wa-txt30. " text displaying on the dropdown
    APPEND ls_valueset TO lt_valueset.
ENDSELECT.
LOOP AT lt_columns INTO ls_column.
    CASE ls_column-id.
      WHEN 'CONCATSTATUSER'.
        CREATE OBJECT lr_drdn_by_index
          EXPORTING
            selected_key_fieldname = ls_column-id.
        lr_drdn_by_index->set_valueset_fieldname( 'VALUESET' ).
        lr_drdn_by_index->set_type( if_salv_wd_c_uie_drdn_by_index=>type_key_value ).
        ls_column-r_column->set_cell_editor( lr_drdn_by_index ).
     ENDCASE.
ENDLOOP.
In view-ini I fill the table which is bound to my alv-table:
LOOP AT lt_list_opportunities INTO lstru_list_opportunities
      WHERE status = ls_opportunity_status-estat AND
     valid_to <= ls_input-bdate AND valid_from >= ls_input-vdate.
    ls_opportunities-valueset = lt_valueset.
    MOVE-CORRESPONDING lstru_list_opportunities TO ls_opportunities.
    APPEND   ls_opportunities TO ltt_list_opportunities.
ENDLOOP.
lo_nd_opportunities = wd_context->get_child_node( name =
wd_this->wdctx_opportunities ).
lo_nd_opportunities->bind_table( new_items = ltt_list_opportunities ).
HOW can I now get the slected dropdown values in ON_CLICK with ON_CELL_ACTION method ?
Thanks for answers !!
Gerd

Hello Abap,
when I have selected the value in the dropdown-box, then the event should start, and then I should have the
selected values of the dropdown box.
Hope you can help me !

Is it possible to have sorting by group and checkboxes in the same ALV

Hi there,
Does anyone know whether it is possible to have sorting and group on one field in ALV and checkboxes set on another field in ALV?
eg.
Fieldname
===========
Name----
Text
Allowance----
Numeric -> Sort & Group
Verified----
Checkbox
How do I code it if it is possible to have grouping and check box all in one ALV. Meaning I want some data that are the same to merge using sort, while still having the checkbox available for my other field (Verified).
Thanks in advance.
Lawrence

hi,
GROUP BY clause is used on database tables with select statement.
sort is used on internal tables.
can u clearly explain y u need group by and sort on the same field.
if u are extracting from dbtable using grou by clause on a field, then no need to sort it again.
if u want sort u can do it by giveing "sort itab by field". thats not a problem.
now coming to check box.instead of using SLIS type field catalog, u use LVC type.
in LVC_S_LAYO, u can fine box_fname.
while defining layout, u declare a variable of type LVC_S_LAYO
AND GIVE BOX_FNAME = internal table field name

Function code for dropdown on OO ALV Grid to trigger user_command

Hi Experts,
I know we can add a dropdown to a column of an OO ALV Grid, set values to the dropdown list and allow the user to select some these values.
However , what I'm not sure is that if we can *assign a function code to the dropdown * which would then trigger the event user_command ( PAI ) of the ALV class so I can handle the changes to when a particular value is selected from a dropdown list, just like we do in normal dialogs.
Now I know that I can register the 'Enter' event and handle the data changes in data_changed event, but that is something I want to avoid the user from doing as far as possible to make the report more user friendly.
Awaiting your valuable inputs and would really appreciate your help.
Thanks & regards,
Advait

Hi Advait,
No problem. Yes, this functionality requires changing the focus to other cell.
I think there is other solution. As the dropdown is kind of F4 activity try this way:
data: it_f4 type lvc_t_f4,
        wa_f4 type lvc_s_f4.
        wa_f4-FIELDNAME = 'CONNID'.
        wa_f4-REGISTER = 'X'.
        wa_f4-GETBEFORE = 'X'.
        wa_f4-CHNGEAFTER = 'X'.
        append wa_f4 to it_f4.
"register F4 event
CALL METHOD g_alv_grid_ref->register_f4_for_fields
    EXPORTING
      it_f4 = it_f4.
"Once you try to pick the value HANDLE_DATA_CHANGED event will be triggered
"Definition
     methods:
     handle_data_changed FOR EVENT data_changed OF cl_gui_alv_grid
                              IMPORTING er_data_changed e_onf4 e_onf4_before e_onf4_after,
"Implementation
METHOD handle_data_changed .
    DATA: ls_mod_cells TYPE lvc_s_modi.
    IF e_onf4_before = 'X'.
      MESSAGE 'Data changed before F4' TYPE 'I'.
    ENDIF.
    IF e_onf4 = 'X'.   "if event triggered by F4
      MESSAGE 'Data changed on F4' TYPE 'I'.
    ENDIF.
    IF e_onf4_after = 'X'.
      MESSAGE 'Data changed after F4' TYPE 'I'.
    ENDIF.
   "here you know which cell was modified
    LOOP AT er_data_changed->mt_mod_cells INTO ls_mod_cells.
     "just example test case, here you can implement your code for modified cells
      IF ls_mod_cells-value >=5.
        CALL METHOD er_data_changed->add_protocol_entry
          EXPORTING
            i_msgid     = 'SABAPDOCU'
            i_msgty     = 'E'
            i_msgno     = '888'
            i_msgv1     = 'Only numbers below 5 are possibe'
            i_msgv2     = 'Please correct'
            i_fieldname = ls_mod_cells-fieldname
            i_row_id    = ls_mod_cells-row_id.
        CALL METHOD er_data_changed->modify_cell
          EXPORTING
            i_fieldname = ls_mod_cells-fieldname
            i_row_id    = ls_mod_cells-row_id
            i_value     = space.
      ENDIF.
    ENDLOOP.
ENDMETHOD.                    "handle_data_changed
This approach works fine for picking value from input help. Never tried it for dropdown list. You have to try it out.

How to avoid roundtrip to server on value select in dropdown box in ALV cel

Dear Experts,
I have WD ALV table where user edits values in the cels using dropdown by key element.
Then after edit he saves whole table. When value is changed in dropdown box the roundtrip to server occurs and it takes noticable time for every cell. My dropdown lists are fixed and are the same for all rows. It is not pleasant user experience and is annoying for user.
Is there a way to disable this roundtrip for each value selection for each cell and transfer all the data for whole ALV table only when I save whole table (separate button "Save")?
Help very much appreciated.
Dmitry

A lot of enterprises, however, actively avoid systems which are locked down to a particular server for very legitimate reasons. If my data center dies in the middle of the night, I sure don't want to have to call your mobile phone so that you can get to a computer, log in to the office network, and get me a new key so that I can finish my emergency failover. If I've got dozens of applications, I absolutely don't want to do that with dozens of different vendors.
It sounds like your problem, though, isn't that users are installing your software on multiple computers it's that they are accessing functionality they haven't licensed. That is generally a much easier problem to solve and doesn't require you to lock anything down to a particular machine. You can create a table LICENSED_CONTENT, for example,
CREATE TABLE licensed_content (
client_id NUMBER,
content_type VARCHAR2(30),
key RAW(128)
)In this case, KEY is, say, a hash (using the DBMS_CRYPTO or DBMS_OBFUSCATION_TOOLKIT packages if you'd like) of the client_id, content_type, and a bit of salt (i.e. a fixed string that only you know). When you sell a license to manage diamond content, you provide a script that inserts the appropriate row in the LICENSED_CONTENT table. When your application starts up, it reads the LICENSED_CONTENT table and verifies the hash before allowing users to access that type of content. This allows legitimate customers to move the software from one system to another but prevents them from accessing new functionality without a new license.
