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

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

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.
Regards,
Murthy

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.
CALL METHOD cl_crm_uiu_prod_tools_search=>eh_onclosepopup_return_product
   EXPORTING
      ir_search_popup = search_popup

Default selection of dropdown value help in bp search for custom field

Hi guys,
i've problem setting a default selection of the value help. I appended a structure containing a field of type CRMT_BOOLEAN to the crmt_bupa_il_header_search and show it at the bp search page.
The default order of the value help is
[ ] false
[x] true
which means that the first entry (false) is selected by default. I want the second entry to become the default entry. I tried to sort the ddlb_table of this field in the get_v_xxx but this didn't had any effect to the value help.
DATA: lt_ddlb TYPE bsp_wd_dropdown_table,
lr_ddlb TYPE REF TO cl_crm_uiu_ddlb.
lt_ddlb = cl_crm_uiu_bt_tools=>get_strcmp_ddlb(
iv_structure = [structure]
iv_component = [my_zfield])
IF NOT lr_ddlb IS BOUND.
CREATE OBJECT lr_ddlb
TYPE
cl_crm_uiu_ddlb
EXPORTING
iv_source_type = 'T'.
ENDIF.
SORT lt_ddlb DESCENDING BY key.
lr_ddlb->set_selection_table( it_selection_table = lt_ddlb ).
rv_valuehelp_descriptor = lr_ddlb.
Is this approach not working at all? After sorting lt_bblb contains the values in correct sequence, the webui is showing the value help as before.
Is it possible to set a selected value in any way?
Thanks and BR,
Sven

Hi Sven Wagener,
what i understand is you want to set the default entry is second value right?
if this is your requirement then go for this procedure.
In redefine do_init_context method and fetch the collection in that collection get your field name and value.
make a condition like this if the value = 'first value of your drop down' then set to second value.
this method will execute only in the initial stage means when ever you login into your business role this method will execute.
example:
lr_col ?= me->typed_context->yournode->collection_wrapper->get_current( ).
check lr_col is bound.
lr_col->get_property_as_string( EXPORTING iv_attr_name = 'DROPDONWFIELD' RECEIVING rv_result = lv_dropdownfield ).
if lv_dropdownfield EQ 'FIRSTFIELDKEY'.
lv_dropdownfield = 'SECONDFIELDKEY'.
lr_col->set_property( EXPORTING iv_attr_name = 'DROPDONWFIELD' iv_value = lv_dropdownfield ).
IF this is not your requirement then give me some screen shorts.
Thanks & Regards,
Srinivas.

Initialising F4-Value-Help for date

I want the F4-Help for a date field to show a month different from the current one.
By default the month containing sy-datum is displayed.
I want the popup to start in another month.
I tried already to create a search help and setting the startdate in a function module of it's group.
This worked in SAPGui, but did not in Web Dynpro.
Does anybody have an idea, how to implement this.
Thanks in advance
Bernhard

You would have to create Freely Programmed Value Help and within the layout of the Value Help create your own Data Picker using the DataNavigator UI element. With the Freely Programmed Value Help approach, you can ignore the current value in the bound context and start with any values you want. The downside will be that it won't be quite a user friendly. Instead of the quick calendar pop in place, you will get the full value help popup window.

Search Help for Infotype Custom Field

Hi,
I have created a search help for a custom field in an infotype. What would be the best way of filtering the help selection based on infotype values such as molga, begda, endda?
Thanks in advance.
/Elvez

Hi Nishanth,
thanks for your reply, perhaps I should clarify my question:
1) I have a custom field in an infotype
2) I have a table containing the search help information
3) I assigned a search help to the custom field
4) I have activated a search help exit
The problem is that the information that I get from the custom field is not sufficient for making the selection. Therefore, I would like to somehow get hold of the addition information, such as BEGDA, ENNDA, MOLGA, to do a proper selection in the search help exit. How can I achieve that?
I read something about function module DYNP_VALUES_READ -would it be possible to call this function module from my search help exit and thereby reach my goal?

Change Search Help for Payment Terms Field

Hi,
I would like to change the Search Help for Payment Terms Field, in Customer Master (KNVV-ZTERM). and in Sales Document. I believe it is the same.
Default is From Table T052 / T052U
ZTERM and TEXT1 Fields
I would like to have
From Table TVZBT
ZTERM and VTEXT
PayT Own Explanation Field.
Can we change the Search Help.

Hi,
The search help for the payment terms is not coming from the DDIC search help..
It is coded in the process on value-request event...
The function module FI_F4_ZTERM is called for this..you have to change this function module in case if you want the values from a different table..
OR do implicit enhancement in the subroutine FORM HELP_ZTERM in the include MF02DFH0 to call your search help instead of the function module FI_F4_ZTERM ..And do the same for the sales order also..
Thanks

SRM Portal - Search help for a custom field

Hi,
I have added a custom field to the SRM Portal (5.0) shopping cart, by adding the field to structures INCL_EEW_PD_ITEM_CSF INCL_EEW_PD_ITEM_CSF_SC.
However, I need to filter the search help for that custom field, based on values & relationships stored in a Z table.
Is this possible? How? Please help.
Thank You.

Currently, my idea would be to create a search help for the custom field & filter the values in a search help exit. However, would I be able to get other field values (standard) from SRM into my search help exit?

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

Assign search help for a screen field in standard program?

Hi All,
Is there any other way to assign search help to a standard SAP screen field? (to be precise i want to assign search help to Recipient field in table control of components tab in transaction IW32/IW31)
I know we can do this by assigning search help through screen painter (by changing standard program, which is my last option).
Any advice/help will be greatly appreciated.

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

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.
