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.

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

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( ).

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.

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

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' ).

Freely programed F4 help

Hello Experts,
i want to create a freely programed F4 help for one of the attribute in my context.
can anyone tell me how to go about it step by step.
Thanks,
gunjan

Hi Gunjan,
Below are the important points which you need to keep in mind while designing this 2nd component ( say COMP2) :
1) Your component which gets displayed as the search help must implement the Interface IWD_VALUE_HELP. (For this double click on your Web Dynpro Component & go to the "Implemented Interfaces" tab. Just specify IWD_VALUE_HELP under the "Name" column & press on enter. The "implementation State" would then display a green traffic light for you signifying that the interface has been successfully implemented.)
2) A window by name WD_VALUE_HELP would have been automatically added to this component when you implement the IWD_VALUE_HELP interface. You need to embed the view which you would like to appear on F4 help under this particular window. (Normally if you had created a MAIN view you would embed this view under the window with the same name as your component. But in this case you need to embed your main view under the window WD_VALUE_HELP )
Now below are the steps to be followed within your main component (say COMP1) in which you have your input field & up on pressing which you want the Freely Programmed Help to Appear.
1) You need to declare a component usage of your help component (COMP2) within your main component. (COMP1)
2) Specify a "Controller Usage" of the Used component within your components view. (Go to the "Properties" tab of your view & click on "Create Controller Usage" button & select the INTERFACECONTROLLER of COMP2)
3) Now change the "Input Help Mode" of your desired context attribute to "Freely Programmed".

How to add the IP address helper command to the switch

Hi
I am trouble shooting a SF 200-48P and I am a bit lost without a CLI not used to the GUI. What I need to know is how to add the IP address helper command to the switch?
I have a number of IP phones which are not getting an IP address from DHCP (PCs which are diasy chained off the phones are all working correctly). On the higher end switches I would have added the IP address helper command to the VLAN and that would have sorted it. However I can't seem to figure out how to do this on the small business switch.
Thanks
Lorne

Thanks Rizwan. I was banging my head wishing they weren't small business switches as I felt lost without the command line!

How to add funded program in report wirter in 4FBUDCON?

Hi!
How can I add the period/month and funded program in the report painter 4FBUDCON? I can't find the any characteristics values of them fromt he basic key figure of HSLT?
Thanks.

Hi Saurabh,
You need to create ABAP program in which you check the values for required process chain in
following table
RSPCLOGCHAIN (Feilds ANALYZED_STATUS LOG_ID)
Depend on values you can trigger next process or you can wait unitil this process chain complete.you need to check status from table using ABAP.
If you are not aware about how to write ABAP program then take help from ABAP Team.

How to add/delete programs.

I am a new mac user and I have just gotten a refurb ibook. It already has itunes on it, but I want to install iLife in order to use imovie. But when I use the install CD it says it can't because I already have a newer version of itunes running. I don't plan to use itunes so I don't care if my ilife is an older version. But I cannot find the way to delete the itunes already loaded so the ilife will install. I cannot find the equivilant of add/remove programs from Windows control panel. Can anyone please help? Obviously, I am FAR from being a computer whiz so any help is MUCH appreciated. Thanks

The other advice posted will help you understand how to install iTunes, but on a Mac, there is no add/remove control panel. The easiest way to get rid of iTunes: open your application folder and drag iTunes to the trash. You can also open the /user/music folder and drag the iTunes folder to the trash. This will get rid of all the music on the computer and the iTunes preference files.
After you install iLife, you can upgrade to the latest version of iTunes.
BTW, isn't there an option early in the iLife installation to choose which components you want to install? If so, just uncheck the iTunes option and install the other components.
