Value help for select options  (pass the selected values to the select opt)

Hi everyone,
I created a custom value help for my select options.
It works fine, when the user clicks on the value help, my own view is displayed, and the user can select the required values:
lt_range_table =
  wd_this->m_handler->create_range_table(
  i_typename = 'ORGEH' ).
* add a new field to the selection
  wd_this->m_handler->add_selection_field(
  i_id = 'ORGEH'
  i_value_help_id = 'MYSO'
  i_value_help_type = IF_WD_VALUE_HELP_HANDLER=>CO_PREFIX_APPLDEV
  it_result = lt_range_table
  i_read_only = read_only ).
The problem is, how can I pass the values to the select option? When the user selects the values in my view, I have them in an internal table. But how can i pass these values to the select option?  I suppose there is declared method for this... but which one?
Thanks
N.

Sorry for the stupid question, but it seems I can't acces my attribute:
I create it in the component controller
NODE: 'APP_DATA'
Attribute: M_HANDLER TYPE IF_WD_SELECT_OPTIONS
Cardinality 1..1
Selection 1..1
Singleton = 'X'
I pass the values int he EDOINIT method of MAIN view:
* Get compnent controller API
  lo_component = wd_comp_controller->wd_get_api( ).
  lo_controller ?= lo_component.
* Get the controler context node
  CALL METHOD LO_CONTROLLER->GET_CONTEXT
    RECEIVING
      CONTEXT = lo_context.
*Get the root node
  lo_node = lo_context->root_node.
*Get the child node
  lo_child = lo_node->get_child_node( 'APP_DATA' ).
ls_app_data-m_handler = wd_this->m_handler.
lo_child->bind_structure( ls_app_data  ).
After this code I test it if the binding is correct:
DATA: ls_test TYPE wd_comp_controller->element_app_data.
CALL METHOD LO_CHILD->GET_STATIC_ATTRIBUTES
  IMPORTING
    STATIC_ATTRIBUTES = ls_test.
The lstest is correct_. It has the reference for the SelectOption
Now, in the SEL_TREE View:
* Get compnent controller API
  lo_component = wd_comp_controller->wd_get_api( ).
  lo_controller ?= lo_component.
* Get the controler context node
  CALL METHOD LO_CONTROLLER->GET_CONTEXT
    RECEIVING
      CONTEXT = lo_context.
*Get the root node
  lo_node = lo_context->root_node.
*Get the child node
  lo_child = lo_node->get_child_node( 'APP_DATA' ).
*Get the data from the node
  CALL METHOD LO_CHILD->GET_STATIC_ATTRIBUTES
    IMPORTING
      STATIC_ATTRIBUTES = ls_app_data.
  wd_this->m_handler = ls_app_data-m_handler.
The ls_app_data-m_handler is INITIAL. There is no value in it.
What did I do wrongly? 
Please help
Thanks

  • Filter Criteria in Value Help for InfoObject

    Hi,
    Is it possible to remove the value from Filter Criteria. When I use F4 for a Field (in Screen) , its showing a poup window (Value Help for Info Object) with some personal values. When I click "More Values" option its showing the General Value List, where I can see the Filter Criteria. When I click "Show Filter Criteria", its showing the Criteria with a Value (This value is coming from the field(Screen) from where I am coming). is it possible to avoid of passing value from my screen field to Filter Criteria ?

  • Initializu00EDng select options field with default values and with NO INTERVALS

    Dear All,
    I have used WDR_SELECT_OPTIONS technology within WD Abap.
    I also have added the fields which have to be taken into consideration.
    lt_range_table =
    wd_this->m_handler->create_range_table(
    i_typename = 'PLANT' ).
    wd_this->m_handler->add_selection_field(
    i_id = 'PLANT'
    it_result = lt_range_table
    i_read_only = read_only ).
    Can I assign two values to this field 'PLANT' whereby the user may take only these values.
    I mean kind of pre initializíng of this select options field with default values.
    Due to this handling it should be prevented that the user can give other values
    except this values.
    Additonally it should be fine whether it is possible to disable the second input field
    of this select options field like NO INTERVALS .

  • Limiting the value help for a user input variable as required

    Hello Gurus,
    I have a requirement :-
    Restrict the value help for a user input variable in a query to only a required set of values instead of the default behaviour. ie instead of having all the values in the master data of that characteristics in the value help.
    How do I go about it? - Do I have to explore the precalculated value set feature?
    If so, please tell me how to go about it in BI 7.I would appreciate if you could explain it in detail rather than sending me a URL because I have gone through most of them but Iam yet to figure out how to create the broadcast setting and subsequent steps.
    Thanks for your time.
    Regards,
    Kris_Hitman

    I believe if the User doesn't want to see any particular values in F4 help then it means they are not intrested in viewing the transaction data related to those values.
    So why don't you restrict that object with the required values. Then the F4 help will automatically display only those values.

  • Dynamic value help for a table field to fill two fields, how to?

    Hi all gurus,
    In SRM 7 I defined a dynamic value help for a single field (ZZ_PROLE_R3) of my header custom table.
    That's the code from WDDOMODIFYVIEW in the webdynpro /SAPSRM/WDC_DODC_CT, view V_DODC_CT:
    DATA: lo_tabnode        TYPE REF TO IF_WD_CONTEXT_NODE.
          DATA: lo_tabnode_info   TYPE REF TO IF_WD_CONTEXT_NODE_INFO.
          DATA: tab_value         TYPE WDR_CONTEXT_ATTR_VALUE_LIST,
                wa_value          TYPE WDR_CONTEXT_ATTR_VALUE.
          lo_tabnode = wd_context->GET_CHILD_NODE( name = 'THCUS' ). "the custom table node
          lo_tabnode_info = lo_tabnode->get_node_info( ).
          wd_this->GET_VALHELP_ZZ_PROLE_R3( EXPORTING iv_guid = lv_guid
                                            IMPORTING ZZ_PROLE_R3_VALHELP = tab_value ). "this method returns the dyn value table
          lo_tabnode_info->set_attribute_value_set( name = 'ZZ_PROLE_R3'
                                                     value_set = tab_value ).
    The method GET_VALHELP_ZZ_PROLE_R3 dynamically builds the value help table tab_value; such table is made up by two fields:
    value : contains the value of the field
    text   : contains a description of the value
    The above solution works; now I'd like to enhance it. The custom table THCUS contains also a field called ZZ_PROLE_R3_DESC, which represents the description of ZZ_PROLE_R3. It is, exactly, the TEXT field in tab_value.
    So I'd like to do as follows:
    - the user clicks on the search help for ZZ_PROLE_R3 field of the table;
    - the above described value help appears;
    - after the selection, both ZZ_PROLE_R3 and ZZ_PROLE_R3_DESC are filled with the selected couple value - text chosen from the value help.
    Could anyone help me achieving such a behaviour?
    Again, a little request... when I open the above value help dialog box, the window itself has a label "Floorplan Manager application for OIF.." that obviously I'd like to redefine (e.g. "Role selection value help"). Is there any way to do that?
    Thanks in advance

    It seems to me - given that your code is in wddomodifyview that you are trying to have different dropdowns per row
    - I'm not sure where you are populating lv_guid - but I'd guess it is an attribute of the row selected? If it isn't then I can't see any reason that you would do this code in wddomodifyview and not wddoinit.
    Hi Chris and thanks for your help,
    lv_guid is the GUID of the document's header; I need to pass it to the method that populates my value help table because the values in it are derived from some fields on the document. (the situation actually is more complex; there's an RFC call on the backend for which the document is intended for to retrieve the data that populate the value help...).
    I'm quite unexperienced on webdynpro and terminology; if dropdown menus are fixed selection option that appears on a field, I guess this is not my case. I did a pair of screenshot to provide an idea of what the solution by now is, and what "I would like to have":
    [Pre-selection (F4 icon on the field in table)|http://imagebin.ca/view/npIsaqF.html]
    [Value Help popup for the field ZZ_PROLE_R3|http://imagebin.ca/view/8fZUh3T.html]
    [Result by now |http://imagebin.ca/view/3PaqdvE.html]
    [Result I'd like to have.|http://imagebin.ca/view/dExR0J.html]
    Chris Paine wrote:
    However - by your comment on the "value help dialog box" I am guessing you are using an input field? If this is the case then I would strongly suggest that you change/enhance the structure of the context node THCUS (btw, better coding practise to refer to it as wd_this->wdctx_thcus when using the get child node construct) so that you refer to an actual SAP ddic search help, if you then associate in the structure the value and text fields then populating the text field should happen automatically. Also you'd have the nice side effect that your value help dialog would be named after the associated ddic search help.
    Thanks for the code suggestion, I'll apply that. For what concerns the context node THCUS... It is, by standard, a node which I can't explictly find in the context for the view V_DODC_CT. The problem is that ZZ_PROLE_R3 and the corresponding description field ZZ_PROLE_R3_DESC of the table must be filled with data retrieved dynamically @ runtime from the backend. So I guess I can't populate a val help referring to a dictionary table/field; I'd rather do as follows:
    - retrieve what's the target backend for the document (to do so, I have to process the document .. that's why the header guid passed to my method);
    - RFC call to a custom method that extracts possible values for the specific backend;
    - bind the ammissible values to the value help.

  • PCH: Value help for Object ID

    Hi Experts,
    I have a question regarding Logical Database PCH.
    We know LDB PCH is OM based and we have  default "Object ID field " and "Reporting period field " at the selection screen.
    I have kept "Reporting period" as "Key date" 31.12.2010. I  wanted to select an Org unit from the "Org. Structure Search" at the ""Object ID field " value help . But I can see the "Org. Structure"  corresponding to  "Today's date" all the time.
    For eg: Org unit 1111111 was delimited on 01.01.2011.  I wanted to se the Org. structure for 31.12.2010. So I put the key date as 31.12.2010. Since the above org. unit is delimited on 01.01.2011, it was expected to see in the Org. Structure at the "Object ID" value help . But unfortunately, it is not displayed, since the Org. Structure is shown based on Toda's date.
    If anybody comes across such a scenario, please provide your inputs .
    Thanks in advance,

    There is a search component that can be used for this purpose.
    This is one function out of several. I don't have the complete implementation at hand but this will give you the first idea.

  • F4 Value Help for Bex Variable (BRAIN646)

    Hi ,
       I set a authorization variable which allow user to select in a Bex query . When I run query and click value help on that variable, the system keep send a warning msg like :
    Value if variable ZVAPLAMS is automatically converted
    Message no. BRAIN646
    Is there any way to suppress this warnning msg?
    Thx,
    Jeff

    Hi Sims,
    I had also the same Problem (BRAIN 646). I've debugged the Query with transaction rsudo -> Execute User as "User with warning" -> Possible Transaction "RSRT" -> Start Transaction.
    The Transaction RSRT is opened and you can now debug your Query by klicking on "Execute + Debug" -> Expand "Variables" and activate "Customer Exit Variable (Before)".
    Don't forget to enter your Queryname.
    You are in Debuging-Mode and set Break-Points (see screenshots)
    1. Set break-point on FORM VALUE_FROM_AUTHORITY_FILL then F8 and get in with F5
    2. Set break-point on  IF l_i1 <> l_i2. then F8 and you get your cursor on IF l_i1 <> l_i2.
    You may see, if internal tables "l_i1" and "l_i2" have the same count of rows. If not take a look at   "l_i1", if there Interval value exist, if internal value do exist. If interval values do exist and in "l_i2" doesn't than you have replace your variable " ZVAPLAMS" with another Variable (selection option). It has to be "Selection Option", than only selection option variable accept single values and interval values.

  • Implementation of F4 value help for a search field which is an EEWB field

    Hi...
                I am trying to create a F4 value help for a search field which is an eewb field.The f4 value help jus need to be a pop up containing the values of the field existing in the system.Since this is a search field the GET_V method cannot be used. I tried implementing it by creating a search help and then using it in the GET_DQUERY_VALUEHELPS method.But the problem when u use the search help is that all the values including the null values and duplicate entries will be populated when f4 is clicked.Is there any way to filter the values that get populated when f4 is clicked?If any other method can be used to implement the functionality please let me know..Thanks in advance....

    Hi,
    the GET_V methods worked for me most of the time. Even in advanced searchs. Only time they do not is if there is a different aproach considered in the GET_DQUERY_VALUEHELPS.
    As the GET_V_ you created obviously was called I suppose you found the correct place to Populate it to be used in the search.
    I do not know what the problem with the NULL values and duplicate entries is you talked about, but it sounds to me the creation of your valuehelp class is flawed. Not the integration into the UI.
    Maybe have a look at SAPs' standard implementations of Search Components. You should get a feeling for how search helps work. See. BT111S_OPPT, BP_HEAD_SEARCH

  • Value help for select-option not filling selection field

    I'm having some problems with a value help on a select-option. I've managed to get the value help displaying the correct values but for some reason can't get it to populate the selection field after I've selected a record.
    I have the following call:
      wd_this->m_handler->add_selection_field(
                          i_id = 'SHORT_D'
                          i_description = 'Program'
                          it_result = lt_range_table

                          i_value_help_type = IF_WD_VALUE_HELP_HANDLER=>CO_PREFIX_SEARCHHELP
                          i_value_help_id = 'ZPROGSTUDY' ).
    where ZPROGSTUDY is a new search help I've set up with an exit to retrieve the values.
    Any ideas ? Thanks.

    Hi Malcolm,
    The code you have is OK. I copied your code into a test program and it worked as expected.
    I used a search help where the possible values are populated in the search help exit, exactly as in your case. The only time it did not work was when read_only = X, but that is obvious also from a visual point of view since the input field is greyed out in that case. The popup also tells you is in RO mode...
    Does your SHLP work when you test it from SE11? Returns values?
    SAP provides a lot of WD4A sample code, see for example component WDR_TEST_SELECT_OPTIONS look for
    select-option fields > special cases > input helps > Non field-specific input help using search help

  • Field in the selection screen as a select option with two default values

    Hi All,
    can anybody tell me how to put field in the selection screen with two defaul values.
    for ex:  selection screen the Account Group KNA1-KTOKD as a select option. The defeault value should be Y001 and Y005.
    please reply ASAP. Its urgent.
    Thanks in advance,
    Madhu

    Hi Madhu,
    Since Select options are nothing but ranges, you can use the following code to add two distinct values to the select options by default.
    s_ktokd-sign = 'I'.
    s_ktokd-option = 'EQ'.
    s_ktokd-low = 'Y001'.
    append s_ktokd.
    s_ktokd-low = 'Y005'.
    append s_ktokd.
    clear s_ktokd.
    However, if you want to mention a range like all the values between these given two values to be considered then u may use,
    select-options : s_ktokd for KNA1-KTOKD default 'Y001' to 'Y005'.
    or
    s_ktokd-sign = 'I'.
    s_ktokd-option = 'BT'.
    s_ktokd-low = 'Y001'.
    s_ktokd-high = 'Y005'.
    append s_ktokd.

  • Value help for a custom field, ENTER press after selection wanted

    Hi all gurus,
    my requirement is quite simple; in an SRM 7 system, a value help (control table Z_V_EKORG) is associated to a custom (input) field, ZZ_EKORG.
    By pressing the search button on it, some fixed values appears in a list but then, after the selection of a value, no refresh/badi is triggered.
    To trigger a refresh (and passage thru CHANGE and CHECK BADIs) the user is forced to press the ENTER key on the inputfield.
    I'm wondering if there's a way to automatically set an action/event (e.g. ENTER key pressed after input) to the selection from the list; I guess it should be a property of the selection for that value help, but I cannot find explicit information on how to do that.
    Waiting for your suggestions and support, thanks

    Hi Matteo,
    Would recommend you to handle this refresh in the post exit of the WDMODIFY method.

    Murthy
