Interface View Enhancements

Hello,
I want to add inbound plug to one standard WebDynpro component.
I've tried to enhance a Window with one inbound plug, but this plug does not appears in interface view inbound plug list.
How to add inbound plugs to interface of standard components? Is it possible?

Hi,
I can't add neither outbount nor inbount plugs to standard component FITV_FPM_START.
I've double clicked in interface view APPLICATION_WINDOW, but I can't click to enhance button, because it is disabled.
Is it possible to enhance standard webdynpro component interface views plugs?

How to make a view created using enhancement framework as Interface View

Dear Experts.
I Created A new View and window by using Enhancement Framework for a standard webdynpro comp. Now i want to use the same window as a UIBB in FPM , since in window properties interface view check box is unchecked it's not allowing me to use a UIBB in FPM.
Kindly answer for the following.
1) Is there any way to make a view a interface ( whcih is by default in nature but while creating from Enhancement framework behaivng Strangly).
2) If there is no way then how to use enhanced (additional View Created in Standard WDA comp) further like in FPM ( UIBB ).
thanks in Advance.

Hi,
Please see [https://cw.sdn.sap.com/cw/docs/DOC-21546|https://cw.sdn.sap.com/cw/docs/DOC-21546]
windows created through enhancement are local to component and hence they are not visible outside.
You need to find other way to provide your interface view to UIBB.

[Solved]How to create ADF interface View

Hi All,
I have a design problem that I need some help with.
In one of the pages in our application, we have two drop down boxes one with account type and another with account name (label) and account number (value).
The account types are Escrow, Credit and Misc (some other types). all three types are in three different tables.
Now the problem is, in the page when the account type is selected, the second drop down box should be filled with respective account numbers.
So my question is Can I create an interface view and implement in all three different account type views and use it for second drop down box.
Thanks in advance for your help.
Thanks

You might do a VO with a union of the three tables - use a custom SELECT like this:
SELECT 'Escrow' account_type, account_number, balance, ... FROM escrow_accounts
UNION
SELECT 'Credit', account_number, balance, ... FROM credit_accounts
UNION
SELECT 'Misc.', account_number, balance, ... FROM misc_accountsUse NULL for any column in a table that does not have that column. I'm not sure if you can use Entity Objects (one EO per table) with such a VO to make the data updatable - it might have to be a read-only VO.
Or create a database view with this SELECT and base the VO on that view instead of a table. You can even make the view updatable with INSTEAD OF triggers and base an EO on the view.

Dynamically change embedded interface view in window

I have a Maincomponent M which embedds in its Mainwindow an interface view V_L from a component definition interface cid L. CID L handles the layout with several views and has two at runtime chosen variants (= cid_L-implementating components ) L1 and L2.
now my wd-application starts e.g. with layout L1 and I want to switch at runtime via a button or an event to L2. how can I achieve this?
Because M embedds in its window V_L (which can be filled by L1 or L2) I tried to delete the component in the usage of L1 and create the new component for showing L2.
but this doesn´t work. should I change some navigation links dynamically? because I thought when I create component L2 the interfaceview V_L is filled and I it´s automatically shown in its higher-ranking Mainwindow from M which embedds V_L.

Hi Thorsten.
Is your scenarion as follows.
You define an outbound plug in your main (e.g. 'OUT') at design time.
Then you start the application and you create a dynmic navigation using OUT
to L1 and embedd L1 in M this way.
Then you click a button and create again a dynamic navigation using OUT as outbound to L2 and embedd L2 in M?
If so you create 2 navigations which will be triggered when you fire OUT.
You can test this by setting the break point on the fire method. Somehow you will come to a point where you will see a table which stores the navigations and should contain 2.
I have a table with authorisation which contains all necessary data for the navigation to a corresponding component. I use the authoridation ID as name for the outbound which have to be created dynamically. And I use a Hashtable to store the value. This is of the type CL_C2S_SAPI_HASHTABLE. I create the object as attribute in view controller. Then each time a link is clicked I check whether the hashtable already contains a value for this authorisation. If not I call
prepare_dynamic_navigation and use the ID as outbound. Afterwards I store it in th hashtable.
lv_outplug = wd_this->outbound_plugs->getvalue( lv_auth ).
*   the navigation to the specified auth is performed
*   for the first time and have to be created.
    if lv_outplug is initial.
      lv_outplug = lv_auth.
      try.
          l_view_controller_api->PREPARE_DYNAMIC_NAVIGATION(
              source_window_name          = 'W_MAIN'
              source_vusage_name          = 'V_MAIN_USAGE_1'
              source_plug_name            = lv_outplug
              target_component_name       = lv_comp
              target_component_usage      = 'USED_COMPONENT'
              target_view_name            = 'W_MAIN'
              target_plug_name            = lv_plug
              target_embedding_position   = 'V_MAIN/UI_COMP_CONTAINER' ).
*         save outbound_plug for later usage.
          wd_this->outbound_plugs->setvalue(
           exporting
             name = lv_auth
             value = lv_outplug
        catch cx_wd_runtime_repository into lr_exception.
          data s type string.
          s = lr_exception->get_text( ).
          raise exception type cx_wdr_rt_exception.
      endtry.
    endif.
    l_view_controller_api->fire_plug(
     exporting
       plug_name = lv_outplug
Hope this helps.

Dynamically embed interface view in window

Hi,
I am reusing the same WD ALV component in different tabs on the same view
of my application. The WD framework does not allow to embed the same interface view of the same component usage more than once on the same view -> error message '... is already embedded in your view...'
So as I don't want to slow down the application and create 5 component usages of the ALV reuse component because of this, I would like to dynamically assign the same
instance interface view to the currently viewed tab. In each tab, there would be a view
container to embed the interface view. I tried calling the method below in both wdDoInit and on the plug handler of the default inbound plug, but no success so far
I implemented the method as far as I understood the saphelp correctly:
http://aiokeh.wdf.sap.corp:1080/SAPIKS2/contentShow.sap?_CLASS=IWB_EXTHLP&TMP_IWB_TASK=DISPLAY&_LOIO=4C60154219FCE12CE10000000A1550B0&_SLOIO=7C3545415EA6F523E10000000A155106&RELEASE=700&LANGUAGE=EN&_SEQNUM=71&_SCLASS=IWB_STRUCT
method EMBED_ALV_VIEW .
data: L_VIEW_CONTROLLER_API type ref to IF_WD_VIEW_CONTROLLER,
L_VIEW_CONTROLLER_API = WD_THIS->WD_GET_API( ).
L_VIEW_CONTROLLER_API->PREPARE_DYNAMIC_NAVIGATION(
              source_window_name          = 'RPM_DASHBOARD_WINDOW' "embedding app window
              source_vusage_name          = 'RPM_DASHBOARD_VIEW_USAGE_1' "own local view containing all those tabs
              source_plug_name            = 'DEFAULT' " inbound plug for the window above
              target_component_name       = 'SALV_WD_TABLE' "alv reuse component
              target_component_usage      = 'SALV_WD_TABLE' "usage name of this component
              target_view_name            = 'TABLE' "interface view name of embedded component
              target_plug_name            = 'DEFAULT' "startup plug for this interface view
              target_embedding_position   = 'CNT1' ). "own view container on view.
Thank you for your help!

Hi Robert,
Check out the following:
In the Wiki they have added a feature about inputfields/dropdownboxes.

Trigger GP process by giving process URL in Interface View outbound plug

Hi,
My Requirement is,
I have 1 GP process implemented in webdynpro.
From 1 of my view I am calling the process completeion(executionContext.processingComplete();) code, written in interface controller.
After this code I need to start the same process once again, without clicking any link.
For this I have created 1 outbound plug in the interface view of my window(out blug for WebDynproCOInterfaceView with parameter "Url").
Then after calling executionContext.processingComplete();, I gave
wdThis.wdGetWebDynproCOInterfaceViewController().wdFirePlugGotoUrl("Process Instantiation URL"); in my view.
but it is giving error,"WDRuntimeException: Cannot navigate from view WebDynproCOInterfaceView via non-existent outbound "
Also I tried to start the gp process througn coding also
what I tried is,
IWDClientUser wdUser = WDClientUser.getCurrentUser();
IUser user1 = wdUser.getSAPUser();
IGPUserContext userContext = GPContextFactory.getContextManager().createUserContext(user1);
IGPProcess process = GPProcessFactory.getDesigntimeManager().getActiveTemplate("EB0B28E08B6011DB0145EB416E0",userContext);
EB0B28E08B6011DB0145EB416E0 is the process ID.
This code I have tried by giving before and after the completion of the previous process(process9executionContext.processingComplete();)
But this also didn't work..No error came. But process didn't start again after thecompleted once.
Please help me out.
Thanks
smitha

Hi Rupam,
thanks for the reply
I have given EXIT type of outbound plug only. But it won't work if the view is in portal.
When I tried to create the process using GP API the process is creating in Background. For me , after the completion of one process , automatically next should trigger and the corresponding view should be visible for the user.
Process is triggering using GP API but, the view is not visible to user.
Please help me
Thanks
Smitha

Add Embed Interface View of a Componenet instance

In a WebDynpro project (not DC), we create two webDynpro components WA, WB.
WB is is declared as Used Web Dynpro Components in WA. When we want to embed the interface view, in the pop-out window, we can see the Component Instances node with a "+" , but we can not open the node to select. This case can be reproduced on some machine, but in another machine it works properly.
We use NW 2004 with SP11, any one know how to solve the problem?

Change Button for Interface View is Inactive

Hi,
I have created a Web Dynpro ABAP component & application.
Now I want to add URL parameters to it.
I went to interface view, I can see "change" button in menu but its not clickable.
Any idea why this is happening?
Thanks and regards,
Amey

Hi Amey,
IF you dont have any interface attributes or methods, there is nothing you can change in Interface View.
For Adding Parameters, goto your Application to add application parameters in Parameters tab.
You can chooose from existing set of parameters or Create a new parameter such as TEST1 & any default value like 1 or A etc .
Now goto your Window method HANDLEDEFAULT & frmo here you can access what value you are getting from the URL Parameter TEST1 by using below code...
data lv_configid type string.
lv_configid = wdr_task=>client_window->get_parameter( TEST1' ).
now IF for your application say zph_test02, if you are running URL as http://xxxxxx.xx/sap/bc/webdynpro/sap/zph_test02?sap-language=EN&TEST1=2
The value lv_configid will have value 2 now when application is launched with that url & parameter TEST1=2.
Thanks,
Phani Mullapudi

Help on Interface views

Hi,
I am aware that there is a 1:1 relationship with Interface view and a window.
1) But I am not sure for the purpose of the inbound plug "Default". What is the significance.
2) What does the plug type - startup / Resume/ Standard refer to ?
I am also aware that if a window has 'n' number of views and the user want to see a particular view on the startup, we have to enable the default option as 'True' in the view properties. There is only one view which can be made to have dafault as 'True'
Any suggestions to help me get clear would be welcome.

Gandolf

Regarding interface views inside a view.

Hi,
We have a screen in which a view uses interface views of two other components.
Depending on the link clicked anyone of the interface view should be displayed in the bottom of this main view.
I am using view container UI element for this requirement. Are there any ways of switching the interface view in a single view container element.. instead of creating two of them, each for one interface view.?
regards
Bharathwaj

Bharathwaj,
Yes, it is possible.
Create 2 outbound plugs in outer view, link them to corresponding inbound plugs of interface views.
Now on action fire one forementioned plugs.

Required to Initialize interface view

Hello guys,
I am facing a strange issue while using viewsets in web dynpro java. The view set (Grid Layout)contains two columns, where the left side view contains the list of orders. when i click an order i navigate to the interface view of another component to display the details of the order. I ll also navigate to other views in the window of the interface view.
Now when i again click the order number on the left side to view the order details, the first view in the interface is not displayed. it only shows the current view which is active in that window. how can i resolve this issue.?
Kindly give me a solution..
Regards,
Karthikeyan R

Hi,
Please check whether the default property of the Interafce View is set to true.
Open the Window Editor -->right click on Interface View -->Check Default.
Thanks and regards

Component Usage / Interface Views

Hi Experts,
I have added two fields in CPGOE_DETAILS/ovefdetails view through AET.
Now I want to attach search help to those fields through compoent usage.
So I have created component usage of BP_HIER in the CPGOE_DETAILS.
I am able to call the search help view : SearchHelpNodesVs because it is default view in Interfave view SearchHelp for the first field.
for the second field i want to call the view : SearchHelpVS which is also available in interface view SearchHelp.
Please suggest the solution.

Hi Naresh,
the window SearchHelp has two different inbound plugs which you have to use.
- IP_SEARCH_NODES opens BP_HIER/SearchHelpNodesVS
- IP_SEARCH_TREES opens BP_HIER/SearchHelpVS
Just use the correct inbound plug to get the search you want.
Best regards
Matthias

Regarding navigation from Interface View

Hi All,
i am trying to pass data from one component to other component via exposing the interface view controller of second component to 1st component via Used Webdynpro Component concept.
I am able to navigate from one component view to 2nd component view with the action of fireplug from 1st to 2nd. but i am not able to do
vise versa.
What i got, after embedding the 2nd view in the 1st component window, inbound plug is created automatically. If in the same view(embedded interface view) i try to place out bound plug i m not able to do. how to get this navigation from 2nd view to 1st view.
Please help me out.
Regards,
Deepak

Hi deepak,
I didnt work on it but giving just an idea....
till now you did....
i am trying to pass data from one component to other component via exposing the interface view controller of second component to 1st component via Used Webdynpro Component concept.
I am able to navigate from one component view to 2nd component view with the action of fireplug from 1st to 2nd. but i am not able to do

now to do vis versa you have to do all this things for other component. I mean expose 2nd component via Used WD component concept. now embed 1st view in 2nd component window. just reverse of what you did till now.
and take a view set where in first view area show the first navigation, and in the second view area of view set show the second navigation.
Am I clear?

Firing the Suspend Plug of Interface View Controller of1 DC from another DC

Hi Experts,
Can you please let me know if it is possible to fire a suspend plug from a Component Controller?
I've been tried it before from View controller on some event and was able to fire the plug successfully but when I am trying to fire the same from the init method of the Component Controller or init method of the view controller, it gives me the below error:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Instance of interface view controller XXXXCompInterfaceView does not exist.
I believe that it is not possible to fire the suspend plug from the Init method of either Component Controller or View Controller.
So, is it possible to fire the suspend plug in one custom method of a component controller if the custom method is called from some another component?
Please let me know.
Thanks & Regards,
Anurag

Hi Prashant,
When I am trying to fire the Suspend plug from my view on click of a button, I am getting the following error:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Cannot suspend embedded component via outbound plug <Plug Name> of view <Interface View Name>
    at com.sap.tc.webdynpro.progmodel.view.ViewManager.fireSuspendPlug(ViewManager.java:209)
    at com.sap.tc.webdynpro.progmodel.view.View.navigate(View.java:533)
    at com.sap.tc.webdynpro.progmodel.view.View.navigate(View.java:462)
Earlier, when I used to fire the plug from my DC; it used to work fine but now my DC is being used as a used DC in another component and since then I am facing this issue.
Currently, my DC is being used as used DC. I am not sure if I use any used DC, it would work or not.
Please respond if anybody has any suggestions.
Regards,
Anurag
