CALL SEARCH HELP IN WEB DYNPRO

Description :
My web dynpro contains some buttons and allow some interaction...
One of the buttons is : 'LOAD DATA'...
I'd like to call a search help when the user PRESSES this button, how can i do that ? maybe a reusable component ???
Thank you...

Hi Stephan,
Well there is a way by which you can achieve this functionality... You need to call the static method HANDLE_VALUE_HELP of class CL_WDR_VALUE_HELP_HANDLER. To use it we simply need to pass in a reference to the context element, and the name of an attribute. It will then run the value help defined in the context for that attribute.
However being SAP internal, the method could change or disappear at any time. So this isn't a reliable approach. You would be better off following the approach suggested by the other users. I am however just quoting it for your inspection.
Suppose I have a context node by name NODE1 & an attribute MATNR under it of type MARA-MATNR. Now up on click on a button I want the search help MAT1 for MATNR to be displayed. Below is the coding for the buttons action handler:
method ONACTIONCALL_VALUE_HELP .
data: wd_node type ref to if_wd_context_node,
        wd_element type ref to if_wD_context_element.
wd_node = wd_context->get_child_node( name = 'NODE1' ).
wd_element = wd_node->get_element( index = 1 ).
CALL METHOD CL_WDR_VALUE_HELP_HANDLER=>HANDLE_VALUE_HELP
    EXPORTING
      CONTEXT_ELEMENT   = wd_element
      CONTEXT_ATTRIBUTE = 'MATNR'.
endmethod.

Search Help with Web Dynpro call on another system

Hi all,
I have to create a search help with web dynpro on a field but the database is on another system... How can I do?
Many Thanks in advance...

I would use a search help exit. Nothing WDA specific here, as this has been possible long before WDA came around. With a search help exit you define the search help like normal, but instead of database table or view being the source of selection, you have a function module. Within the coding of this function module you can call an RFC to read data from another system or call a web service if you need to bridge over to something that isn't ABAP based.

Search help for Web Dynpro using the SAP-search help

Hi,
Im trying to create a generic search help for Web Dynpro using the SAP-search help. It should working so, that I construct a Web Dynpro-component, that gets the data of the search help from the SAP-system, interpreted it and creates the ui-elements and the needed context generic.
The mapping between the Input field of the customerview and the right search help is to be made with an xml-file, which contains the information: name of the view, the input field, the search-help-name and the name of the field that will be returned.
The xml-file is reading from a helper-class. That helper-class contains any information, witch need the search help-component as well as the customer-component.
The initialization takes place in the method wdDoModify of the customer. The call of the search help from the customer should be implement with an Action, witch is bound to a Button(create dynamic in the helper-class behind the input field).
In a second foot should be create a plugin for eclipse, witch insert the used files (search help component, helper class, ) in the project. In addition it should create the call in the customer generic.
It would be great if someone can give me a feedback!

Hi Mike,
The BlanketAgreement.exe is a reference to the executable that will be created when you compile the solution you created in Part II - Part III. I think there is a mistake in the tutorial because it asks you to name the project 'Blanket' which means that by default the executable will be called Blanket.exe and not BlanketAgreement.exe. The tutorial also misses the step asking you to compile the Blanket project before you go on to create an installer. You should compile your Blanket project in Release mode before creating an installer. By compiling the project you'll get a Blanket.exe file in the bin folder of your Blanket project which you then need to add to the installer per the instructions.
SAP do offer development courses in some areas and there is training material here on the SDN and on the SAP partner portal (and maybe the customer portal as well). Try searching this forum for 'training' or 'tutorial' and you should get a few links. There's also a development certification.
Personally I'd recommend you give yourself a little project to work on and just get stuck in
Kind Regards,
Owen

Creating Search Help for Web Dynpro ABAP (FPM) Forms

Dear All ,
I am very new with SAP HCM P&F with FPM form. I am stuck with field search help functionality in FPM form. I have created on search help using
Web dynpro component to get all travel requests for all employees and linked it to FPM form field and its working fine....
But.... my requirement is how to filter travel request based on the PERNR (employee number) field in FPM form.
I think it can be achieved by using importing parameter LISTENER of interface IF_WD_VALUE_HELP_LISTENER but I am clueless how to pass PERNR to this interface to get travel requests for only employee number in field PERNR.
Kindly help me out in this issue.
Chohan

Use this code in set_value_help_listener
for e.g to read effective date.
wd_this->help_listener->f4_context_element->get_attribute( EXPORTING name = 'EFFECTIVE_DATE' IMPORTING value = wd_this->gv_eff_date ).

Search help in web dynpro

Hallo dear all,
i defined a search help in the ABAP Dictionary and want to use it in a web dynpro. The search help is based on the data base table /BIC/PSCPLPROD (selection method).
It shall be used in a web dynpro that presents select-options (among others) for the field /BIC/SFINCUST of the table /BIC/SCPLPROD.
How can i realize that the selct-options field can automatically use the predefined search help?
I must explain additionally that the mentioned select options field is alreday linked to an other search help which unfortenately is unseless in this case. So Iwant to "overwrite" this link with the link to my search help on the DDIC.
Your answer would really minimize my project troubles. Many thanks in advance.
Best regards Dorothea.

why can't you have another field and have the required search help attched to it.
if you can control this at Dictionary level then the Problems at WebDynpro side is minimum.

                      city.

How can I click to hande OVS and Search help for Web Dynpro

Once the F4 help is clicked, the event OVS of IF_WD_VALUE_HELP_FORWARD is triggered.
Here I would like to change the value list of F4 help list, I implemented a class and a method that handle that event.
Since event only has importing parameter, how can I change the exporting paramter?
Thanks
Xin.

hi,
when you click on F4 help, Event OVS is triggered.
now you can define an Event handler for OVS event.
Inside this Event handler , you can change the Value help list.
Inside the event handler there are three different phases to achieve this :
Phase 0 :configuration phase.
Phase 1 :Read values of the original context entered by user in Search Criteria.
Phase 2 : call business logic for a table of possible values.
Phase 3 : apply result.
Refer the SAP Standard Component : Demo_Value_help.

Search help in Web Dynpro in ABAP

Hi,
I am starting with WD for ABAP (NW04s). I am using PA0022 table as model and displaying these values on the view. By default most of the fields like country, education centre, Faculty, Branch, Score come with an F4 option. But the value displayed in these fields are always key fields(Numeric), which would not make any sense for the end user. Now I would like the Text/Descriptions to be displayed against each field.
Can anyone help me out.

Hi Guys,
I am new to ABAP WD. We are workin on ABAP Stack of the Portal with no DB Tables n data. we have to fetch the data from R/3 and display it on the Dynpro screen.
But here the problem is the Standard Search Help attached to the data elements cannot fetch any data, as by default it searchs the ABAP stack for the data. Is there any work around for the same wherein i can fetch the data from R/3 and display it when user requests for the search help.?
Please let me know.

Calling a Method in Web Dynpro ABAP

Hi Experts,
I have created a class in se24 and called its methods in web dynpro by simply creating its object. It is working fine. After that i came to know that method should be called through creating a service call in WD.
What is the standard way and why?
Thanks
Ravindra.

Hello Ravindra ,
I think the better way is to create an assistance class ( Say A1) and create an attribute (Say AC1) as object of your class ( Say C1 ).
In the costructor of you assistance class A1 you can instanciate the object of C1 .
Now inside a method of assistance class you can call the method of C1 any time because AC1 is already instantiated .
MVC architecture recommends you should have separate method to aceess the data and you write your business logic in assitance class methods .
Hope this will help you .
Regards
Vivek
