How OO ABAP & ABAP WEBDYNPROS are Related??

HI,
i am new to WEBDYNPRO and shifting myself from OO ABAP to WEBDYNPRO IN ABAP.
Kindly let me know how OO ABAP and webdynpro ARE INTERRELATED.(in terms of coding or in terms of environment)
Regards,
Dev

Hi Dev,
Welcome to ABAP Dynpro!
Now I am 10 months old to ABAP Dynpro.I have explored a lot.Now you were asking about how much ABAP/OOPS one should know and topics one should know.
In my view you should be aware with fundamental of OOABAP like
class , methods , interfaces and static attribute.Being WD ABAP Dynpro guy you should be in position to use ABAP classes and methods in it.
Just take case if you want to access element from node in context ...such code by wizard Appears ....
DATA:
zobj_bbp_ior_util TYPE REF TO zcl_bbp_ior_util,
node_ztiornode TYPE REF TO if_wd_context_node,
elem_ztiornode TYPE REF TO if_wd_context_element,
stru_ztiornode TYPE zsior.
navigate from <CONTEXT> to <ZTIORNODE> via lead selection
node_ztiornode = wd_context->get_child_node( name = if_request_ior=>wdctx_ztiornode ).
get element via lead selection
elem_ztiornode = node_ztiornode->get_element( 1 ).
now you should be in position to understand and make use of classes like
' wd_context' etc. .You should know what it does then you will use it method
like get_child_no.
Hope I have cleared you doubt.
Cheers,
Darshna.

How does ABAP webdynpro architecture works......

Hi experts,
I am new to Abap webdynpro and i have a task to finish.
Basically i gone through many documents on WDA, but was able to understand very little.
I have following questions --
1. When u create component, what is the use of component controller?
2.. What exactly context and context node difference? Do we need to create an attribute(input box, button etc), under one context?
3. How can i read the date entered by user? where to read? If i want to read a particular iinput box data and save it to database table, how and where it has to be done?
4. How can i read the table data, complete table of UI?
5. What is an interface controller/component?
I still have lot of doubts about understanding MVC architecture, but I am so so sorry as I have little scope OO abap, so fining difficult to understand.
Kindly if someone explain me I would be greatfully thankfull to you.
Thanks in advance,
Niraja.

Hi Niraja,
I am replying to your questions 1 by 1.
+When u create component, what is the use of component controller?
+
Ans A component controller contains the context,attributes, methods etc for a component. No component can exist without this.Even a view has its own controller having same contents.
All the tabs which you see after clicking on COMPONENT CONTROLLER constitute the controller.
What exactly context and context node difference? Do we need to create an attribute(input box, button etc), under one context?
Ans: Context itself is a context node, but the only difference is that its the root and has unchangeable properties.It has a fixed cardinality of 1..1 where as a node can have different properties.
All nodes and attributes for different UIs are created in the context only.
How can i read the date entered by user? where to read? If i want to read a particular iinput box data and save it to database table, how and where it has to be done?
Ans: Data can be read in form of nodes and attributes. Every UI element for example an Input field will be bound to a attribute.
You can read these values by code ( use CODE WIZARD).
You can code in any methods given under method tabs.
You can create your own methods like event handlers for buttons and different events. You can write all your queries in these methods
+How can i read the table data, complete table of UI?
+
Ans: If u mean by reading the whole node data, I would suggest you to use code wizard and understand the code.
5. What is an interface controller/component?
Ans: If you want to share your component and make it available for use in other components you define your make your methods and context visible in this controller .
Please see the link below for whole Web Dynpro ABAP help.

I would suggest you to understand things and try them and then come with doubts.

Pass pernr from employee search iView to abap webDynpro in Related Activity

Hi All,
I have seen many threads explaining how to pass pernr from employee search iView to custom ABAP webDynpro application in the "Employee profile" page. Also seen sap note 1112733.
I am trying to launch custom ABAP webDynpro application from "Related Activities" view found in the employee information page in MSS. I want to pass pernr selected from Employee Search iView to the ABAP webDynpro application in "Related Activities" view.
In the ABAP webDynpro application, I am listening to the portal event (as per note 1112733) but the ABAP webDynpro can not catch the event.
Anyone has passed pernr from employee search iView to the ABAP webDynpro application launched from "related activities" view?

Hi Ashutosh,
can you tell me exactly what you did? I have the same issue.
Thanks,

How to call a RFC of a remote system from an ABAP webdynpro component

Dear Experts,
I am a newbie in ABAP Webdynpro.
I am working on a requirement where I have a webdynpro component on ECC system.I need to call a RFC located on CRM system from my webdynpro component on the ECC system.
How do I do that ?? Please help.
Regards,
Mamai.

Calling RFC from some other system is same as local except the difference is that you have to give destination name while calling.
And the regarding the method of calling it depends on your FM.
if it is big RFC with complex structure, you can create the service call for it with destination given as RFC desitination.
if it is simple straight forward RFC you can directly call it.
for creating RFC service call call use this method
1. Starting the Wizard
To start the wizard, position the cursor on the Web Dynpro component to be edited in the object list at the left margin of the
workbench window. Open its context menu and choose the entry Create->Service Call. The wizard is started and leads you
through the creation process.
Press Continue.
2. Choice of Controller
On the second dialog window of the wizard, you can choose whether the service call is to be embedded in an existing
controller or whether a new controller is to be created for this purpose. Service calls can only always be embedded in
global controllers u2013 that is, in the component controller or in additionally created custom controllers. It is not possible, to
embed service calls in view controllers.
a. Select radio button Use Existent Controller
b. Do not change the default entry for component: <CC name>
c. Enter for controller COMPONENTCONTROLLER
d. Press Continue.
3. Service Type and Service Selection
a. You now select, which service type should be used for this service call. Select radio button Function Module. Fill the
destination here. Press Continue.
b. Select the service: for Function Module enter <RFC name>. Press Continue.
4. The Required Methods and Context Elements
On the two subsequent dialog windows, default values are listed for giving names to the context nodes and attributes
required by the service call as well as to the required methods. The proposed names are based on the names of the
embedded service, but you can change them as required. However, heed the respective notes in the corresponding dialog
box.
a. Adapt Context: Select from Nodes/Attributes . Press Continue.
b. Specify Method Name: leave all entries as provided: Component: Controller: COMPONENTCONTROLLER Method: EXCUTE_ Press Continue.
5. Completing the Choice
When you have confirmed the last dialog box, the generation is triggered. Afterwards you now have the required methods
and contexts at your disposal for using them within your Web Dynpro component.
or if you want to call directly the use the call statement with destination

How to Trigger a Workflow from ABAP Webdynpro

Hi All Gurus,
I have the following urgent requirement, my client is implementing HR and there is a requirement, where is a ABAP Webdynpro component in which we have integrated a Adobe Interactive Form. When the user calls this from through Portal and fills out the relevant data and submits it, a Workflow in the backend ECC system should lauch,
I am not familiar with, this concept although I have worked in Workflow this is the first time I am interfacind with ABAP Webdynpro and Adobe Interactive From.
Can you please let me know in steps what needs to be done to make the workflow trigger for my scenario and also the specific settings to be done in the bacckend.
Regards,
Pratima Jain

Hi,
If you are using HCM Processes and Forms, the Workflow and form are not directly related, thats true.
But the method in the task calls the corresponding webdynpro application which responds to the action triggered by the user in turn to trigger the workflow and update the data in the HR Master Data.
There are 3 layers 1. UI (webdynpro which launches Adobe Interactive form based on ISR Framework)
2. Workflow
3. Backend framework (used for retrieving F4 helps, default values, save data in the infotypes).
for more documentation, please refer it on help.sap.com.
http://help.sap.com/erp2005_ehp_03/helpdata/EN/82/b6b94278560c31e10000000a1550b0/content.htm
hope this helps.

How to display HTML files using ABAP Webdynpro?

Hi,
I have a html index file and a bunch of other files accessed by the index file in a specific directory on the SAP server. I'd like to display the index file via ABAP webdynpro and allow the users to click on what they need to see. How can I achieve this using utilizing the ABAP webdynpro technology ?
Thanks!

Hi Thomas,
Thanks for taking the time to answer my question.
I have the main html file and all other files needed by the main file in one directory on the application layer of SAP. I'd like to provide the user with a link, by clicking on which they should be able to get to the main html file using the browser. This is just a standalone application.
I can try the approach using BSPs, however, I'm new to that area. Could you point me in the right direction to get started?

How to create interactive forms in ABAP WebDynpro

Hi Experts,
we are trying to create our first interactive form with the "how to guide for ABAP WebDynpros".
Unfortunatelly we have a big problem on Step 17, where we want to save the created WebDynpro Application. After safing the system shows a pop up with following error message:
"you are not authorized to use function - Netzwerkadministration". Although we have all the necessary access rights in the system (ERP/Developer User).
But if we go on and create a service call (it's a guided procedure) for an existing BAPI, we can't select the function module interface parameters that we want to add to the context via checkboxes. There are no checkboxes available. but the how-to-guides shows checkboxes.
is maybe the first error the reason that we can't select the function modules? Please help. If you need the how-to-guide, please give me your eMail and I will provide it to you immediately.
Thank you very much in advance and regards,
H.-J. Kersten

How to open a brfplus Catalog from abap webdynpro screen.

How to open a catalog from abap web dynpro application. and also what roles are to be provided to a user for restricting access only to the objects in the given catalog.

Hi Pratik,
do you use NetWeaver 7.0, Enhancement Pack 2 (or higher)?
Then you can then define an own UI mode class and set it via SET_UI_MODE( ) in IF_FDT_WD_UI_EXECUTION before you call EXECUTE_CATALOG_BROWSER().
An explanation how to define a UI mode class is available in the chapter "Configuration through a UI mode class (7.0/7.1 EHP2)" of the document [Embedding a BRFplus Object in an ABAP WebDynpro Application|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/50e44bf9-9135-2d10-2ea2-b13e5be8661d]
Hint: With help of the interface IF_FDT_WD_USER_CONFIGURATION you have the possibility to hide views in the navigation view by using the respective, listed parameters (e.g.. GC_PARAMETER_FAVORITES_VIEW). Please be aware of that the configuration is just available to adapt the UI, it does not fulfill the requirements to act as an authority concept. If you do not set the parameter GC_PARAMETER_HIDE_SETTING_DLG of the interface IF_FDT_WD_CONFIGURATION to false, the user is also able to change it via the configuration dialog in the BRF+ workbench.
With the current available BRF plus standard authority concept you can prevent that the user can see the content of objects like applications but you have no influence to prevent the user from seeing UI artifacts like the repository tree. Please consult the documentation to learn more about its capabilities.
Kind Regards,
Marco

Hi Thomas:
It worked fine the 1st time. Second time when the user clicks on the button to open up the popup it dumps.
Here is the code in the action for popup:
data: l_cmp_api type ref to if_wd_Component,
        l_window_manager type ref to if_wd_window_manager,
        l_api type ref to if_wd_View_controller,
        l_text type string_table.
l_cmp_api = wd_comp_controller->wd_get_api( ).
l_window_manager = l_cmp_api->get_window_manager( ).
if wd_this->m_popup is initial.
    wd_this->m_popup = l_window_manager->create_window(
             window_name = 'DOCQSOW'
             button_kind = if_wd_window=>co_buttons_ok
             message_type = if_wd_window=>co_msg_type_none ).
           component_usage_name = 'DOCQUERY_USAGE_1'
    l_api = wd_this->wd_get_api( ).
    wd_this->m_popup->subscribe_to_button_event(
          button = if_wd_window=>co_button_ok
          button_text = 'Transfer'
          action_name = 'POPUP_CLOSED'
          action_view = l_api ) .
    wd_this->m_popup->SET_REMOVE_ON_CLOSE( abap_true ).
   endif.
wd_this->m_popup->open( ).
Second time when the popup tries to open, I get the following error:
Method: RENDER_WINDOW of program CL_WDR_WINDOW_RENDERER========CP
Method: RENDER_WINDOW of program CL_WDR_CLIENT_SSR=============CP

Is there a way to destroy the instance of the m_popup?
