Value help in a disabled field?

Hi all,
In a web dynpro Abap application I want to add a field with a search help(OVS).
The thing is that I don't want the user to enter data in the field but he should be able to select a value using the F4 functionality.
Do you think that it is possible with Abap Web Dynpro? If yes, how?
Thanks a lot for your help.

Up to my knowledge, I don't think it's possible in WDA. Alternatively, you can do one thing;
Create an Input field as read only mode and create a button say Get values after this Input field. In the Action event of this button you can call a F4 and then select the entry and pass this value in the Input field.
Hope it works for you.

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

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 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

Personalised Value Help in Select-Option field WD ABAP

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.

Value Help for Date in Z date field

Hi,
I am working on CRM 7.0 and am pretty new to the system.
My query is that i have created an assignment block with value attributes created in a Z table. In that particular Z table there is one date field.
I need to assign value help to that particular field and i am not able to do so.
Can anyone please help me in this regard.
Thanks in advance for the time you will be investing in answering my cause.
Best Regards,
Saurabh Garg

Hi,
      Make sure that the technical field type is a date type(say, DATS). Then also make sure that you have a m_getter for that attribute. For example,
method GET_M_START_DATE.
    DATA: attr    TYPE dats,
          dref    TYPE REF TO data.
    GET REFERENCE OF attr INTO dref.
    metadata ?= if_bsp_model_binding~get_attribute_metadata(
         attribute_ref = dref
         attribute_path = attribute_path
         name           = 'START_DATE'                      "#EC NOTEXT
*      COMPONENT      =
         no_getter      = 1 ).
endmethod.

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' ).

Selection Screen - Text instead of Key in the value help

Hi ,
I have implemented selection options for Web dynpro.
The value help for the selection fields displays the key of the selected value (standard).
I would like to know if there is an option to display the text (instead of the key) in the field.
Key Text
01    AAAA
02    BBBB
03   CCCC
So if I select say - 01 and 03 in the value help, Can I display AAA, CCCC in the field (or next to the field)
Thanks,
Sri

Hi jakob,
Thankyou for your quick response.
I did a basic model with the help of a documentation which i got from this forums.I created a iView and from there i used Bapi "BAPI_SALESORDER ".
I created a Input Form and a outpot form (table view).I tested model and am able to get the output.but when i try to deploy it is giving me the error.
And i think am not paring any formulas here.
Please guide me.

Value help.. in version 7.0?

Hello all,
I have VC 7.0 installed in the system. We have an option to provide the value help, for a particular field.
In the wizard, when we select the data service(i.e, RFC), it says not aple.plicab
Later, we get a value help button, but no value appears,even tho it enters the RFC.
Can someone tell me on the kind of RFC, for a value help fieldi.e, kind of import and export details for the RFC.

Hai,
if your providing value help for particular field u have select key and value field . then only the data will pouplate in the value help.

Dump in Value-Help Component for date

I created a Value-Help-Component for date fields. (I cannot use the standard value help, because I need the help to start in the month, the user is working on).
I am using the Date Navigator to select a date.
If I first change the month with an arrow of the date navigator and then select a date I get a dump in the method IF_WD_CONTEXT_ELEMENT~GET_ATTRIBUTE_REF in line
attr_info = me->node_info->if_wd_context_node_info~get_attribute( name_only ).
, because the element does not have a node_info.
If I just choose a date in the preselected month (without using the arrows of the date navigator) everything is fine.
Does anybody have an idea??
Many thanks in advance.

I found the "solution" to the problem myself.
I used the method bind_structure in the component containing the date navigator.
After I replaced it by set_static_attributes it worked without producing dumps.
Very strange!

Value help does not work for ONE person only !

Hi,
we have a strange problem. In the Web IC, we are using a standard value help for the country field for a Business Partner. This works fine for everyone (ie, it picks up the country and slots it into the field) except one person. For her, it never returns any value into the country field. We are guessing that it's not Web IC related but is something in her browser settings etc...but haven't been able to pin it down. Can anyone offer any advice on this ?
thanks for looking.
Malcolm.

Hello Malcolm,
If this error occurs for one user only it's definitely related to the clients PC.
Did you already delete all temporary files and the cookies on that PC? Usually this does the trick!
If this does not solve the problem, try to let that particular user login on another PC where the problem does not occur. (If the error does occur on another PC too it's probably profile/authorization related)
Hope this helps!

Joost
