Value Help for Model in java webdynpro

I have created an OVS in web dynpro. I would like to query the database(ABAP Table in SAP R/3).
How do I do it in webdynpro.
Thanks and Regards,
Narayani

Hi Valery ,
I tried using the ICMIQuery but there seems to be a problem. I am getting the following exception:
"java.lang.UnsupportedOperationException: Not supported for generic queries"
This is the code that I tried for query.
Selectquery is the query model class that I have created.
I have even tried without the wdcontext also.
SelectQuery query = new SelectQuery();
wdContext.nodeSelectQuery().bind(query);
WDValueServices.addOVSExtension("OVSTEST",attributes,query,listener);
Thanks.

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.

I realise that this is rather a lot - so if you have any specific question please do respond - hopefully I or someone else will be able to clarify.
Thanks again for your help; additional info as well as code examples would be highly appreciated

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 ?
Thanks

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 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

How to implement Value Help for Product ID?

Hi,
I have a Z-Component where I want to use the value help of the Product ID. I found several components which use this value help for Products but I can't get it to work in my component properly.
Does anybody have a short tutorial how I need to proceed?
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.

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.

Some fields from R/3 have automatic value help for input field on WD

Hello,
we have imported a Model from RFC/JCo (ABAP) with several fields. One of them is "IWAER" of SimpleType Iwaer and "Built-In-Type" string in J2EE. Though the enumeration of this type is empty, WebDynpro mystically generates a value help if the type is assignet to an ImputField. On the ABAP-side component type is IWAER with data type CUKY and in domain WAERS which has a value table TCURC (instead of fixed values in a value range).
Where/why does WD find out that this is a currency-field and where do the values in the value selector come from?
Best regards,
Manuel

Hi,
at least for the ModelData-Connection (BAPI-Call) there is no data being transferred besides one value for each field.
I don't know if the MetaData-Connection of JCo is able to get more information (e.g. key-value-pairs for the domain or type the field belongs to,..) than just the structure of the interface.
-> Where and how do these EVS-values come from without doing something?
Best regards,
Manuel

How to disable calculator value help in Web Dynpro Java

Hello ,
Does anyone know if it's possible in CE 7.2 to disable the automatic help calculator when using input fields of the type integer or decimal?
I ve done SAP Note 1406153 in server. But it doesnt work.. value help is still appear..
Best Regards,
Rasim

1. Create a smart form in the R/3 side
2. Now create a function module with the corresponding export parameter:
3. Make sure that the function module is marked remote enabled.
4. In NWDS create an Adaptive RFC model which points to the FM created in R/3 under the webdynpro application
5. Now create an application and view inside it to display the PDF and Insert a frame inside the view
6. Create a value node and an attribute say url of type string inside that node and bind it to the source
7. In the doInit() method place the following code
>    ZTest_Pdf_1_Input input = new ZTest_Pdf_Input();
>    wdContext.nodeZTest_Pdf_Input().bind(input);
>    try {
>            wdContext.currentZTest_Pdf_InputElement().modelObject().execute();
>            }
> catch (Exception e) {
>                        e.printStackTrace();
>            }
> wdContext.currentInternalElement().setUrl(convert(wdContext.currentOutputElement().getBin_File()));
Inside that view create a method to convert the string to url so that it can be passed as a string to the setUrl method of the currentContextElement() , say convet(byte[] doc_content) which return a string.
Inside that methos write the following code,
>         String url = "";
>           WDWebResourceType webResType = WDWebResourceType.PDF;
>            IWDWebResource webResource = WDWebResource.getWebResource(doc_content, webResType);
>            try {
>                        url = webResource.getURL();
>            }
> catch (Exception e) {
>                        e.printStackTrace();
>            }
>            return url;
Hope It will be helpful

F4 help for Time field in Webdynpro Screen

Hi Experts,
I'm using TIMS data type for my Time field. In ECC we will have F4 function for the same data element, but in Webdynpro screen, am not getting the F4 help.
I got some information from SCN that I need to go for some custom search help. But with which reference to the table, am I want to create it.
Please let me know, is there any other possible way to create F4 for time field for webdynpro.
Even I tried to use some standard search help, but am getting an error as 'Sending of dynpro ' ' not possible. No window system type specified'.
Expecting valuable information from you experts.
With Regards,
RAM.

Hi RAM,
For time field, there is no SAP delivered search help in WDA , so we need to go for freely programmed search help.
Please refer the below link, in which Mr. Thomas, has provided the links for search help document you can follow and create new search help component
and also nugget of the component which can be imported using ZSAPLINK program.

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.

Value Help for Date inverval in Variable Form in Visual Composer

Hi all,
I have created a variable form which has Date interval with value help as one of the parameters.
when i click on the value help and select any date interval then it is displayed as say '20081015:20090101' but when i submit this value i get an error "INVALID_VARIABLE_VALUES".
this variable is working fine when i manually enter the interval as '10/15/2008:01/01/2009'.
is there any way where we can input the date interval value as '10/15/2008:01/01/2009' using the value help.
any help is highly appreciated.
regards,
RK,.

Hi Ramakrishna,
Value help is considered as a popup iview in visual composer. You can change the fields in popup iview like normal iview. Drill down the popup iview of the value help and change the date format using DSTR function.
Try the below link for change the date format.
