Integrate Freely Programmed Value Help in Select option WDR_SELECT_OPTION

Hello All,
I have created Freely Programmed Value Help name (ZVALUE_HELP) by using IWD_VALUE_HELP.I have develop an application(ZSELECT_OPTION) which uses the resubale component WDR_SELECT_OPTION for select option.i want search help for one of my select option input field .
i wrote the following code.
*initalise the used component
data lo_cmp_usage type ref to if_wd_component_usage.
lo_cmp_usage = wd_this->wd_cpuse_ci_serach_help( ).
if lo_cmp_usage->has_active_component( ) is initial.
lo_cmp_usage->create_component( ).
endif.
* add a new field to the selection
WD_THIS->M_HANDLER->ADD_SELECTION_FIELD(
I_ID = 'ZCI_STATUS'
IT_RESULT = LT_RANGE_TABLE
I_READ_ONLY = READ_ONLY
I_OBLIGATORY = ABAP_FALSE
I_VALUE_HELP_TYPE = IF_WD_VALUE_HELP_HANDLER=>CO_PREFIX_APPLDEV
I_VALUE_HELP_ID = 'ZVALUE_HELP'
when i execute the select option application n click on search help button i got error "Component usage ZVALUE_HELP does not exist.

hi Abhsilasha,
I think your code is some thing wrong.
you have to assign free value help like below method.
in the attribute( the select option field ) properties, you will find input help mode property, in that select 'freely programmed'.
then you willl get some more fields, there you have to provide ZVALUE_HELP
of follow reema suggestion in below link

How to created Freely Programmed F4 help in Select Options

hi,all
   I have a probelm about how to created a Freely Programmed F4 help in Select Options,and put help value into select options field
Thanks and Best Regards

Hi Haung,
You need to use FREE_HELP not the component name.
Modify you code as below:
   LT_RANGE_TABLE_V = wd_this->m_handler_V->create_range_table( 'ZCYPHDATE' ).
wd_this->M_HANDLER_V->add_selection_field(
      i_id                         = 'ZCYPHDATE'
      it_result                    = LT_RANGE_TABLE_V
      i_value_help_type            = if_wd_value_help_handler=>CO_PREFIX_APPLDEV
      i_value_help_id              = 'FREE_HELP'
      i_no_intervals               = abap_false ).
Hope this helps you.

POWL: Freely Programmed Input help for Selection Criteria possible

Hi,
is it possible to add a freely programmed value help to a POWL-selection field? In this case the use of OVS is unsufficient from the user perspective.
Can anybody guide me?
Thanks, Elke.

I dont intend to create another search help component for my 2nd input field because if let say i have 20 input fields that requires search help, does that means I need to create 20 search help components and embed 20 of them into my parent component?
NO need of creating 20 more search helps if you have these 20 attributes in the result table of the value help.
just check in the help from where the help is getting called and then pass the value accordingly.
here is a sample code where i am checking whether the search help is called from ID field or Location field and then passing
the required info back.
lo_listener = wd_comp_controller->value_help_listener.
lv_attrib_name = lo_listener->f4_attribute_info-name.
IF lv_attrib_name EQ 'ID'.
lo_listener->f4_context_element->set_attribute( value = lv_id
name = lv_attrib_name ).
ENDIF.
IF lv_attrib_name EQ 'LOCATION'.
lo_listener->f4_context_element->set_attribute( value = LOC
name = lv_attrib_name ).
ENDIF.
wd_comp_controller->fire_vh_data_selected_evt( ).

Freely-programmed value help for a single ALV cell

Greetings everyone,
I have a freely-programmed value help that works beautifully when attached to the context element of a single field, but now I'm needing to use it in an ALV for a specific cell. Is there a way to shut off the dropdown for all of the rows (cells) in the column where I don't need it? Or, is there an appropriate workaround that can deliver the same results?
I've found several posts that address similar issues, but nothing for this exact problem.
Thanks,
Jason Block

I take it from reading your description what you want is a little more complicated than just controlling the read-only property on the input field. If I read you properly you still want to have all the cells in a column to be open for input, just on some of them you want to disable the value help. Is that correct? See these screen shots for clarification:
If you focus on the the input field in the first row, you get the value help:
http://www.flickr.com/photos/tjung/2714133068/
However if you go to the second row and focus on the same input field in this column, you don't get the value help:
http://www.flickr.com/photos/tjung/2714133094/
If this is what you want, then buckel up because this was a challenging one. The problem is that the value help specification is not done at the UI element level, but instead at the context attribute level. Therefore it can't be as simple as controlling a property on the inputField itself. What you will need to do is extend the context node that you have bound to the ALV. You need to add a second version of the attribute that is bound to your input field. In this second version you can set the value help specification to Disabled:
http://www.flickr.com/photos/tjung/2713320505
Notice from the screen shot that I also added another attirbute called CVAR (type STRING). We will need that later. It will be used to store which cell variant show be used on a particular row.
Now we must go to the place in your code where you fill the context node with data. You will need to copy the data from your primary attribute to your secondary one. In my case I was copying the values from CARRID to CARRID2. Of course for update, you would need to merge the data back together before saving it back to the database. I also set a simple odd/even pattern of controller in the cell variant. I assume you will have some actual business logic that controls this:
data odd type boolean value abap_true.
   loop at lt_f_r_sflight[] assigning <ls_f_r_sflight>.
    clear ls_c_r_sflight.
    move-corresponding <ls_f_r_sflight> to ls_c_r_sflight.
    move <ls_f_r_sflight>-carrid to ls_c_r_sflight-carrid2.
    if odd = abap_true.
      odd = abap_false.
    else.
      odd = abap_true.
      ls_c_r_sflight-cvar = 'NOVH'.
    endif.
    insert ls_c_r_sflight into table lt_c_r_sflight[].
endloop.
lo_r_sflight->bind_table( lt_c_r_sflight[] ).
Next is the logic in the initialization of the ALV. We will need to create two input fields - each bound to the different context attributes. We will make the one the primary cell editor. The other will become the cell editor of the cell variant. We then tell the column where it can get its cell variant value from:
DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.
lo_cmp_usage =   wd_this->wd_cpuse_alv( ).
IF lo_cmp_usage->has_active_component( ) IS INITIAL.
    lo_cmp_usage->create_component( ).
ENDIF.
DATA l_salv_wd_table TYPE REF TO iwci_salv_wd_table.
l_salv_wd_table = wd_this->wd_cpifc_alv( ).
DATA l_table TYPE REF TO cl_salv_wd_config_table.
l_table = l_salv_wd_table->get_model( ).
l_table->if_salv_wd_table_settings~set_read_only( abap_false ).
DATA input1 TYPE REF TO cl_salv_wd_uie_input_field.
DATA l_column TYPE REF TO cl_salv_wd_column.
l_column = l_table->if_salv_wd_column_settings~get_column( 'CARRID' ).
CREATE OBJECT input1
    EXPORTING
      value_fieldname = 'CARRID'.
l_column->set_cell_editor( input1 ).
DATA input2 TYPE REF TO cl_salv_wd_uie_input_field.
CREATE OBJECT input2
    EXPORTING
      value_fieldname = 'CARRID2'.
DATA l_cv TYPE REF TO cl_salv_wd_cv_standard.
CREATE OBJECT l_cv.
l_cv->set_key( 'NOVH' ).
l_cv->set_editor( input2 ).
l_column->add_cell_variant( l_cv ).
l_column->set_sel_cell_variant_fieldname( 'CVAR' ).

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

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_read_only = read_only
                      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

F4 Value Help in select option

Hi ,
I have created one WD component as value F4 help to use into another component's select option. I am able to use this component in the Input Field UI element by selecting free programming as input help mode and name of this component used as input help component usage . I dont know how to pass this component in select option . can any one help me please to do this functionality.
Thanks ,
Aashish

I have not tried them out please check it -
IN IF_WD_SELECT_OTPIONS~ADD_SELECTION_FIELD parameters list
I_VALUE_HELP_TYPE     Importing     Like     IF_WD_VALUE_HELP_HANDLER=>CO_PREFIX_NONE
I_VALUE_HELP_ID     Importing     Type     WDY_VALUE_HELP_ID
I_VALUE_HELP_MODE     Importing     Type     WDY_MD_VALUE_HELP_MODE_ENUM
I_VALUE_HELP_STRUCTURE     Importing     Type     DDOBJNAME
I_VALUE_HELP_STRUCTURE_FIELD     Importing     Type     FIELDNAME
I_HELP_REQUEST_HANDLER     Importing     Type Ref To     OBJECT
we have to use them -
pass the FVS type to I_VALUE_HELP_TYPE = IF_WD_VALUE_HELP_HANDLER=>CO_VH_TYPE_BACKEND (check for teh other attributes in IF_WD_VALUE_HELP_HANDLER) or IF_WD_VALUE_HELP_HANDLER=>CO_PREFIX_APPLDEV
to this I_VALUE_HELP_ID i think we have to either pass the FVS comp usage name or FVS webdynpro component name
I guess this is also used I_HELP_REQUEST_HANDLER - i think we need to pass the object reference of FVS or somethihg like that..
Make sure you given them in CAPS for these parameters.
Just try them out....Hope this helps

Personalised Value Help in Select-Option field WD ABAP

Hi
I would like to know how I could provide the user with generic value help. I am using the Select Options in a Web Dynpro(ABAP) Application.
Regards

Hi
The key word here is "generic value help". This means the values that I want to fill the drop down with changes all the time based on various criteria. I need to fill the help values within the ABAP code based on the values in internal tables.

Freely Programed Help for select-option field

Hi,
how can i set freely programmed help for select option field, i mean while adding selection field what are the parameters that are important for freely programmed help.
i have implemented iwd_value_help in one component comp1 and declared the usage of comp1 in comp2 where i actually defined the usage of select-option component.
i used parameter i_value_help_type = if_wd_value_help_handler=>co_prefix_appldev while adding selection field, however when i presss F4 icon, the following message is coming
View WD_VALUE_HELP does not exist within the component WDR_SELECT_OPTIONS
Please suggest where i am doing wrong??

Hi Kranthi,
Please help me to understand your design.
Why would you like to create a Freely programmed value help for select-option?. why not use wdr_select_option directly ?

Search Help in Select - Options for Time field

Hi,
I have a select option which is a time field.
For date field the F4 help is automatically generated.
How to get F4 help for time field.
Regards,
Remo

Selection-Options or normal field - it doesn't matter. There is no system delivered value help for a time field. This is documented in the online help:
There is no automatic F4 help for data element TIMS.
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/47/9f724642314aabe10000000a42189b/frameset.htm
You would have to create your freely programmed value help if you want something like the time value help available in the SAPGUI.

How to add Freely programmed input help in FPM Search UIBB?

Hi Experts!
We have a requirement to create search UIBB in which the input field should have a freely programmed input help.
I see that WD_VALUE_HELP parameter can be set to the component name and it displays the freely programmed help as well in the application.
However, I am still digging to implement the search help open and close events of the component.
I have used the Freely programed value help standard demo object " FREE_VALUE_HELP " which shows the value in the help popup however, the selected value is not returned in the input field.
I am also unable to find any Interface as provided for implementing OVS in search UIBB as well...
Please help.

Hi Aliaksandr,
Thanks for your response.
I have checked this WDA application demo_value_help .... but it is a normal WDA application.
However, I want use freely programmed search help in Search UIBB using FPM.
I found that we can provide the component name used as freely programmed search help in the attribute WD_VALUE_HELP of Interface IF_FPM_GUIBB_SEARCH.
https://help.sap.com/saphelp_nw74/helpdata/en/03/f2474b6d9a49f4b5a3ed6f04decf22/content.htm?frameset=/en/56/d151c3ba7b4b2e82068a084cb991f3/frameset.htm
And it displays the search help as well when I do F4 on the field of Search UIBB. But, we need to provide event handler for events - VH_WINDOW_CLOSED and VH_WINDOW_OPENED of the search help component (Component which is provided in WD_VALUE_HELP) some where in the Feeder class, in order to get the selecteed data from the search help, which I am unable to do.
Do you have any idea of such implementation?
Appreciate your response!

Help required on Freely Programmed Input help

Dear all,
I have developed a component, say comp1, in which i have implemented the interface IWD_VALUE_HELP.
In the respective view(MAIN) of Comp1 i have a dropdown which contains a list of company codes fetched from T001 table.
Apart from these two, I have also embedded the Main view into the window WD_VALUE_HELP.
Now, I have created another component, say Comp2, in which i Used the dynpro component Comp1, and also in the MAIN view of my Comp2. Now in the MAIN view of Comp2 I have created a input field from the node T001 in the context which contains the single attribute BUKRS type String. In the properties of the BUKRS attribute I have also changed the Input help to "Freely Programmed" and linked to the component for the Input help.
After this, I have created the application for my component Comp2. When i run the application and when i press F4 on the input field i am able to get the window from Comp1 component, and a dropdown with values.
Now the question is, How can i pass the value selected in that window of Comp1 into the input field of Comp2? we do the same in OVS, when ever a value is selected from the Hitlist, it will be cascaded into the input field, just like that i want to do here.
Please suggest me how to do this, and also please tell when to go for Freely programmed Input help and its advantages.
Thank you,
Shashi.

You can do as suggested already and use interface nodes and cross component mapping; but that is all really not necessary. It creates a situation where you calling application is too dependent upon the freely programmed input help. You want to try to avoid the situation where the calling application needs code or mappings to communicate with the input help.
That is easy to do because the framework passes all the information you need into the freely programmed input help via the value_help_listener object.
Part of the Freeley Programmed Input Help Component should be the component interface IWD_VALUE_HELP. This comes with a component controller method called SET_VALUE_HELP_LISTENER. This allows your freely programmed value help to capture this object called listener of type IF_WD_VALUE_HELP_LISTENER. I generally just store it awa into a component controller attribute.
With this listerner object you have direct access to the context attribute in the calling component. You can query information about the calling UI element and of course set values directly back into it. The listener is a hugely helpful object and should be the way you interact with the calling component whenever possible. Here is small example:
set single attribute
wd_this->value_help_listener->f4_context_element->set_attribute(
exporting
name = wd_this->value_help_listener->f4_attribute_info-name
value = l_time

Problem in Select Option Freely programmed F4 Help

Hi All,
I had a Component 'A' where i used select option. I used Freely programmed search help for the select option field.
If i click F4 in the select option field it will call one component in which i have one more select option in component B.
In component B select option field if i manually entering value and search and click apply values button the values are comming in the select option field in component A.
But if i pressing the F4 in Component B and search and click apply values the value are not comming in the Component 'A'.
If i open again component B and closing it without any action the value is coming in component A.
If i debugged and see the WDDOMODIFYVIEW of tHE WDR_SELECT_OPTION is not getting called for component A.In which it has Rendering delta method of CL_WDR_SELECT_OPTION.
Any idea about this.
Regards,
Ganesh.

hi Ganesh,
i have read your post several time and i am still not able to get hold on your problem. Probably it is to do with your complex approach of nested select_option, i can not judge why you did this way. I would advice you to step back and see it for yourself
1)if it is need to have nested select_option
2)check component initialization and destroy
2)check event subscriptions
