Problem while using Component Usage

Hi,
I am using Component - BT116IT_SRVO/TableWindowOVE as component usage in my component - SRQM_INCIDENT_H. Added this as assignment block.
The problem is :
It is not showing any button as "Edit List" as it is showing in Service Order. And I am not able to see any values in dropdown to select "SHOW".
Can you please help me, how to enable Edit List and how to make it work as same in Service Order.
Thanks,
Sandeep

Hi Sandeep
Check whether you have added below formate to the ComponentUsages of SRQM_INCIDENT_H. If not add like below. It will get you out from the issue.
ComponentUsage :CUItemTable
Used Component : BT116IT_SRVO
InterfaceView: BT116IT_SRVO/TableWindowOVE
InterfaceView :TableWindow
Once you added component usage properly as mentioned above, you can able see below lines of code in Repository.xml of SRQM_INCIDENT_H. BUT Dont cahnge manually in Repository.xml

<Window id="SRQM_INCIDENT_H/MainWindow" default="TRUE">
<EmbeddedView id="CUItemTable.TableWindow"/>
</Window>
<ViewSet id="SRQM_INCIDENT_H/IncidentOV">
<EmbeddedView id="CUItemTable.BT116IT_SRVO/TableWindowOVE"/>
</ViewSet>
Now restart your browser and test the application.
Thanks

No component usage created in enhanced web dynpro component

Hi experts,
I am facing the following problem:
I'd like to enhance a web dynpro component in order to add a popup window. The popup is triggered by the process_event method. So far everything works just fine.
But the popup needs to know some context attributes from the main component, and I cannot create a component usage in order to set the context mapping.
Does anybody know how to solve this issue?
Thanks and regards
Jan Phillip Höft

Hi!
Thanks for your answers first of all.
I need the popup to be a stand alone web dynpro component, so I guess the assistant class doesn't do the trick because I can not access it in the popup component.
The popup is called when the business object is saved. So that the user is asked to notify other users that the document has changed. In this popup the user should fill in the message and click a button to send it and close the popup.
So I tried the OBN approach as well but with two problems :
1. I cannot close the popup component by coding (button click) because it has no direct parent component
2. The save event is not run through properly so the document stays locked by the user. But I didn't look into this yet.
So it would be perfect to have an embedded popup component which is based on a stand alone web dynpro application so it can be closed properly but it need at least access to the guid of the main component.
Anybody got an idea for this?
Thanks and regards

External component usage with interface node

Hi everyone,
I have component A , which has an interface node with Input element checked:
Nodes
Node Name     IF_HROBJID
Interface Node     1
Input Element (Ext.)     1
Dictionary structure     ZHR_HROBJID_LIST
Cardinality     0..n
I have another component: Component B Where I want to bind a table to this interface node.
In component B :
1. I definied the Componenet Usage of component B in the componenet controller.
2. I drag & drop the IF_HROBJID node to the component controller's context (the node is mapped)
But when I try to bind a table, I always get the " The Mapping to Node COMPONENTCONTROLLER.1.IF_HROBJID Has Not Been Completed. " error.
nd_if_hrobjid = wd_context->path_get_node( path = 'IF_HROBJID' ).
nd_if_hrobjid->bind_table( lt_if_hrobjid ).
Can someone tell me what is the problem, and how can I solve it?
Thanks
N.

Hi,
Here you are trying to use component A in component B right?
Then what you need to do is:
1. Declare the component usage of A say A_USAGE in properties tab of component B.
2. Create a node say 'DATA' in component controller of component B. The node 'DATA' would have the same structure as the node in your component A.
3. Fill the node 'DATA' in component controller's method.
4. Under your webdynpro component B, you will see Component Usages -> A_USAGE. open interface controller inside that.
    Goto context tab and drag the 'DATA' node from component controller of B on to the node in interface controller.
Hope this is clear!

How to switch between different instances of component usage?

Hi All,
Need your help.
My application is about "Program Management", there is a table on the upper level which displays several program header data. in the lower level of the screen, I have a view container in which I embed another component to display program details.For instance,if you make a lead selection on one row of the table above, then the lower part will display the program detail.
Here is the problem: e.g. first, I make a selection on program '001', then I'll create a component usage of the program detail and I put it into a component uage group, second, I make a selection on program '002', then the same like above, I create another component usage and put it into a component usage group. Now I have two instances of program detail component usage, when I select program '001' again, how can I switch back to program '001' detail.
So, I'm trying to achieve multiple instances of program detail so that user don't need to wait for loading program details everytime.
Thanks in advance.
Regards,
Aaron

Hi Aaron,
As you are using two separate components, they would be having two separate views to display the required information.
In the onleadselect of your main view ( where you are using the individual views of the other components via the viewcontainerUI ), you have to embed the following code:
DATA lo_api_main TYPE REF TO if_wd_view_controller.
lo_api_main = wd_this->wd_get_api( ).
CALL METHOD LO_API_MAIN->FIRE_PLUG
 EXPORTING
 PARAMETERS =
 PLUG_NAME = 'OP_TO_TWO'
Create two outbound plugs in your window, and link them to the inbound plugs of the individual views of used components.
I am embedding the code of my onleadselection:
method ONACTIONSELECTED .
 DATA lo_nd_table_data TYPE REF TO if_wd_context_node.
 DATA lo_el_table_data TYPE REF TO if_wd_context_element.
 DATA ls_table_data TYPE wd_this->element_table_data.
 DATA lt_table_data TYPE wd_this->elements_table_data.
 data lv_selected_index type i.
navigate from <CONTEXT> to <TABLE_DATA> via lead selection
 lo_nd_table_data = wd_context->get_child_node( name = wd_this->wdctx_table_data ).
get element via lead selection
 lo_el_table_data = lo_nd_table_data->get_element( ).
 CALL METHOD LO_EL_TABLE_DATA->GET_INDEX
 RECEIVING
 MY_INDEX = lv_selected_index
case lv_selected_index.
when 1.
data lo_cmp_usage type ref to if_wd_component_usage.
lo_cmp_usage = wd_this->wd_cpuse_comp_one( ).
if lo_cmp_usage->has_active_component( ) is initial.
 lo_cmp_usage->create_component( ).
endif.
 DATA lo_api_main TYPE REF TO if_wd_view_controller.
lo_api_main = wd_this->wd_get_api( ).
CALL METHOD LO_API_MAIN->FIRE_PLUG
 EXPORTING
 PARAMETERS =
 PLUG_NAME = 'OP_TO_ONE'
clear lo_cmp_usage.
when 2.
DATA lo_api_main TYPE REF TO if_wd_view_controller.
lo_api_main = wd_this->wd_get_api( ).
CALL METHOD LO_API_MAIN->FIRE_PLUG
 EXPORTING
 PARAMETERS =
 PLUG_NAME = 'OP_TO_TWO'
data lo_cmp_usage type ref to if_wd_component_usage.
 lo_cmp_usage = wd_this->wd_cpuse_comp_two( ).
 if lo_cmp_usage->has_active_component( ) is initial.
 lo_cmp_usage->create_component( ).
 endif.
endcase.

Illegal component usage

Hello,
I created an SC, DC etc. on a fresh NWDI. Created the track on that SC, mde references and checked in SAP-JEE, SAP_BUILDT, SAP_JTECHS (7.00 SP7) (SDA I ttok from my Netweaver Server, had none on NWDI). And I created a new WebDynpro Project on that track with NWDS 7.00 SP 6 (may that be the cause of Problem?).
The Problem is I get on my still empty project after syncing all SC Archives:
Check for used DCs failed: Illegal component usage: compartment "MY_COMPONENT" does not use compartment "sap.com_SAP_BUILDT_1" of used DC "sap.com/tc/bi/bp/webDynpro"; using DC: myDC(MYComponent)
Any clue what that shall tell me????
I think in generell that procedure is much to complicated with going first to SLD for SC and Product, then to CMS to create a track, give references to SCs, you just have to know which you need. Then you have to check these SCs in and so on (I never understood that step at ALL why that is needed...). To much steps to make errors...
Best regards,
Frank

Sorry in the whole dropdown I see nothing of this three SCs. I'm at the right place to add the three SCs, but I just don't FIND them, because naming ist totally different here.
Documentation in the nice "do something but don't tell me how" style of SAP sais:
Create a product and software component in System Landscape Directory (SLD). Define the build dependencies required for J2EE development on the following software components:
+ SAP_BUILDT
+ SAP_JTECHS
+ SAP-JEE

Okay found them finally Its
+ SAP J2EE ENGINE <Release> (SAP-JEE <Release>)
+ DI BUILD TOOL <Release> (SAP_BUILDT <Release>)
+ SAP JAVA TECHNOLOGY SERVICES <Release> (SAP_JTECHS <Release>)
for all other who are searching for them. Found it at:

Problem in Concurrent usage

Hello friends
I have a group of 25 users in SAP BW 3.5 and I want them to create their own InfoArea. However the problem here is that when one starts creating his InfoArea, all the other users are denied access or locked i.e only one user can create a InfoArea at a time. How can I enable concurrent access so that all of them can create their InfoAreas at the same time.
As of now the roles assigned to the users are:
IDES_BW_ACRM_DEMO, IDES_BW_ALL, IDES_BW_CO_MANAGER, IDES_BW_RETAIL.
Thanks in Advance

Error: Component Usage MODEL Cannot Reference Component Usages

Hi,
I have a scenario where my main component acts as a place holder for views from several view components, all of which implement a common component interface.
The data (contexts) for all of these views are obtained by context mapping from a common component (model component). Hence, I need to pass reference of model_comp to each of the view comp's through "enter_referencing_mode" done in a method called set_model( ) in each view comp's component controller.
I have taken care not to explicitly instantiate the model in any view comp., but instantiate the model only once in my main comp and pass its reference around.
However, I get a dump "Component Usage MODEL Cannot Reference Component Usages" . The CX_WDR_RT_EXCEPTION is raised in the method ENSURE_NO_REFERENCING_MODE of class CL_WDR_COMPONENT_USAGE.
(If I remove data-binding of any UI elements placed on the view components (i.e, model context values never used), it no longer dumps! But that's not possible.)
Please help!
Best regards,
Adithya

Hi Sascha/Regina,
Thanks for your replies. As far as re-modelling my application goes, we are too far ahead with this to re-think on the refactoring of model into assitance classes. I will take into account for all subsequent developments.
However, could you please provide me with some tips which could help solve my problem: Model component context is used first as the view is loaded as soon as I navigate to the next step in the Roadmap. I am not instantiating explicitly or having any reference to model component's cotnext in WDDOINIT of comp. controller of any view component.
The code for the set_model method (to pass the model comp's reference around) is as follows:
method SET_MODEL( )
DATA: l_ref_model TYPE REF TO if_wd_component_usage.
l_ref_model = wd_this->wd_cpuse_model( ).
l_ref_model->enter_referencing_mode( model_usage ).
Also, suppose I have two component usages (one for the model comp, one for a custom-built value help comp) in each view, should both be instantiated in the main comp. first and the instances of both be passed around? If so, how do I do this, using the same method -(above)?
Many thanks,
Adithya

Need some help regarding the component usage

Dear ALL,
I have one scenario something like this .
I have a main component say ZComp1 and in it i have created one view in which we two drop downs and i have 28 view containers depending upon the drop down values these view containers will be visible here all the view container i am using for displaying by means of component usage (i.e 28 compoenents i am calling into my main ). So now when i run my main application it is taking minimu of 2 mins to display the screen . To test whats the problem i have written some code in the handle default of main window and set the break point what i observed is quite surprising that when i run the apllication it takes hardly 2 mins of time to reach my handledefault method (which is the first one to trigger when i run the apllicatin) . Please suggest me what can be doen to overcome this issue. or suggest some alternative to improve performance.
Note : When there is less amount of data in the screen then it takes less time to execute or else it takes hell lot of time plz suggest :(.
Awaiting for your valuable suggestions.
Regards,
Sana.

Hi Misbah,
28 VCO are too much in a view.
So, try to revamp teh design and reduce the VCO's in a view.
Another thing would be, Every WDDOINIT, and WDDOMODIFY view of the used components would be called when you try to load the component at first.
In your case that is happening, and please check and confirm it.
A proper modular design would be a better approach in handling the situation.
Good day!

SPRO Define My Messages Widgets Define Widget Component Usage / Custom MyIncidents*

Hello everybody,
I am trying to add a custom component usage into
Tx: SPRO > Define My Messages Widgets > Define Widget > Component Usage
like this
Is there an howto somewhere available for this that I can use it in the configuration of the start page widgets "my own messages / incidents":
Kind regards
Update:
In the meanwhile I found that BSP component AIC_HOME is including componentusages named like the standard component usages given in the customizing table under "Define Widget". So I guess I have to enhance the component by my own componentusage with a similar functionality.
I don't know if anyone will ever respond of any of my posts one day but here is
Update 2:
I am stuck now at that Component Usage. When I try to delegate OP SINGLESELECTION to DYN_NAV and visa versa it does not show me an entry to select from.
Update 3:
Well, I first had to add the view within Runtime-Rep. editor > ViewSets > Ov.Page <add< like the standard view of the "MyMessage..."-kind. Now I have all possible selections. Was this the final solution? .... tbc ...
Update 4:
At least in the UI configuration tool i can save now permanently based on one component usage:
BUT the filter which should come along with the component usage does not work.
Last update due to success and problem solution:
Finally there is a need for enhancing the AIC_HOME Component-Controller @
WD_USAGE_INITIALIZE
Just modify the code like this:
CASE iv_usage->usage_name.
 WHEN 'ZMyMessageWidgetITTicket'.
 cl_ai_crm_mymsg=>set_active_switches( iv_usage ).
 cl_ai_crm_mymsg=>set_defaults( iv_usage ). " Reported By My Organization
 WHEN 'MyMessagesReportedByMyOrg'.
 cl_ai_crm_mymsg=>set_active_switches( iv_usage ).
 cl_ai_crm_mymsg=>set_defaults( iv_usage ). " Reported By My Organization
Now your custom component and all stuff around that should work with all the filters and extra drop down buttons, etc..
Nice to see that I started with a big question mark around the component usage (unfortunately described as "Define Widget") and on my way to the finishing line I found out that I had to make myself a hole new assignment block.
Hint:
If you stumble over this error:
Exception-Klasse
CX_BSP_WD_INCORRECT_IMPLEMENT
Fehlername
Programm
CL_BSP_WD_OVW_VIEWSET=========CP
Include
CL_BSP_WD_OVW_VIEWSET=========CM00A
ABAP-Klasse

Zeile
27
Then you have forgotten to edit BSPWDV_EHSET_ASG via sm30. There you connect your enhancement-set (which you use to enhance AIC_HOME) to the client.

Solved by myself..
Used the set_changed_by_client method of the IF_WD_CONTROLLER.

Illegal component usage: compartment

Hi experts,
We have a Track on NWDI for CAF and WebDynpro development that depends on 12 SAP SCs, those are: CAF, CAF-MF, COMP_BUILDT, ENGFACADE, ENGINEAPI, ESCONF_BUILDT, ESF, FRAMEWORK, MMR_SERVER, MOIN_BUILDT, SAP_BUILDT, WD-RUNTIME. Our CAF DC /caf/ejbmodule is not compiling with build error message:
ERROR: Check for used DCs failed: Illegal component usage: compartment "mycompany.com_COMPONENTSERVICES_1" does not use compartment "sap.com_COMP_BUILDT_1" of used DC "sap.com/bie/sca/scdl/contributors/ejb"; using DC: com.sap.tc.devconf.internal.DCProxyMake@152d5de
Build failed with errors.
At CBS, the COMP_BUILDT is not compiling as well, even after the reimport of the DCs on CMS Transport Studio. On CBS Details of build are "USAGE IS FORBIDDEN BY SOFTWARE COMPONENT".
Searchig on SDN I´ve found this Wiki (NWDI)(CMS)Problems-P0007 that leads to SAP Note 669669. After the update of SLD CIM to model version 1.6.16 and CR Content SAP_CR 7.0 we made "Update CMS" and also reimported the SAP DCs on that track, but the error didn´t disappear.
What am I doing wrong?

Did you manage to solve the problem?

Dynamic create Component usage and embed it in view container

There is a view_container_uielement VC_TEST in view V_MAIN, in wd component ZTEST.
I created a web dynpro component named ZWDR_TEST and add it into the wd component ZTEST.
    gr_comp_test = component->create_cmp_usage_group(
      name = 'TEST_GROUP'
      used_component = 'ZWDR_TEST' ).
    lr_comp_usage = me->gr_comp_test->add_component_usage(
      embedding_position = 'V_MAIN/VC_TEST'
      name = 'TEST'
      used_component = 'ZWDR_TEST' ).
    if lr_comp_usage->has_active_component( ) is initial.
      lr_comp_usage->create_component( component_name = 'ZWDR_TEST' ).
    endif.
    ifc_test ?= lr_comp_usage->get_interface_controller( ).
I thought the wdr ZWDR_TEST was embeded in the view V_MAIN in the position VC_TEST by the embedding_position parameter.
But in the result web page, there is no ZWDR_TEST in the position of VC_TEST.
Could any one explain why?
Thanks

Actually it is pretty simple. From the embedded view you can use the APIs to get access to the hosting window object.
data l_api_v_new_attachment type ref to if_wd_view_controller.
l_api_v_new_attachment = wd_this->wd_get_api( ).
data window_controller type ref to if_wd_window_controller.
window_controller = l_api_v_new_attachment->get_embedding_window_ctlr( ).
data window type ref to if_wd_window.
window = window_controller->get_window( ).
window->close( ).
