1) Types of ABAP UI Technologies
Ans: Webdynpro for ABAP, BSP
2) MVC Architecture Concepts and usage of the same in ABAP Webdynpro
Ans: As per the MVC Architecture there is a clear separation between flow logic, view and the Business
Logic. View holds all the UI elements that are visible in the UI, Controllers have the flow logic.
Controllers are of different kind (Component Controller, View Conroller,Window Controller).
Business logic is held in the Model which is in the form of Assistance class
in webdynpro context.
3) Difference Between the View Container and the Transparent Container
Ans: View Container holds the views, there can be multiple views assigned to the view container but only
one view can be active(viewed) at a time. Transparent holds the webdynpro UI elements, A layout type
can be associated with it.
4) What does a Model Class Consists of
Ans: Model Class is the Assitance class in webdynpro. It contains the Business logic in the form of
methods, Global data & Constants in the form of Class Attributes. The Model class can be accessed in
webdynpro component using the attribute wd_assist->. Note: All the visibility properties of the
Class are applicable when accessing the class using the object wd_assist.
5) What is an Assistance Class and How is it Instantiated in Webdynpro
Ans: Assistance Class is the model class which would act as the data provider for the webdynpro
component and it is instantiated by the webdynpro component during the run time and no explicat
instantation is required.
6) Design Patterns in Webdynpro(GAF,OIF,QAF Etc)
Refer to the link:
FPM Concepts in Webdynpro
7) How do you debug an web based Application
(Could be from ABAP Webdynpro, BSP or CRM Web UI)
Ans: External break-points should be used to debug web UI's.
8) How do you create a ALV Report/Editable ALV in Webdynpro
Ans: ->Add the Standard ALV component to the web dynpro Component.
->Use Components tab: Ex: ALV_MATS type SLV_WD_TABLE
->Create a context node with the table field information to be displayed
->Write the ALV Default Code for table display
->Set the read only attribute to false to switch to editable mode using
the method set_read_only of the interface
IF_SALV_WD_TABLE_SETTINGS implementing class
CL_SALV_WD_CONFIG_TABLE).
Ans: Navigation between Views is through Plugs(Inbound and Outbound),
10) Usage of Plugs in Webdynpro
Ans: Plugs are used to Navigate between the views. Parameters can be passed using the plugs similar to
interface parameters of function module or a class method.
11) Usage of Webdynpro Component Controller
Ans: Component controller is used to the store the Global attributes and Methods of the component.
Attributes/methods declared in the component controller are visible through out the component and they
are accessed using the attribute wd_comp_controller outside of component controller(like
views,windows etc) All the context nodes defined in the component controller are
visible in all the views and windows of the component.
Ex: if a variable called gv_count is defined in the component controller, it can be accessed in the view
using the syntax wd_comp_controller->gv_count.
12) How do you access a Context Nodes and elements Programmatically
Code required for accessing the Context Nodes can be written using the webdynpro code wizard.
For Ex: if there exists a Node Node1 with cardinality 1:1 and has 3 Attributes to it Att1, Att2,Att3. The
attributes can be accessed using the below code.
data: lo_nd_node1 type ref to if_wd_context_node.
data: lo_el_node1 type ref to if_wd_context_element.
data: ls_node1 type wd_this->element_node1.
lo_nd_node1 = wd_context->get_child_node
( name = wd_this->wdctx_node1 ).
lo_el_node1 = lo_nd_node1->get_element( ).
**Read Node1
lo_el_node1->get_static_attributes(
importing
static_attributes = ls_node1 ).
**Write to Node1
lo_el_node1->set_static_attributes(
13) Message Areas in Webdynpro
Message areas are created in views to display messages (Error,Success,Warning,Info).
WD allows to have multiple Message errors in a view but throws an error when the view is displayed.
Use the code wizard to get code for raising error messages. Few of the message classes and methods
are: Interface: if_wd_message_manager.
methods: report_t100_message.(used to report message from the message class)
14) Concept of OTR(Online Text Repository) and its Usage
OTR's are similar to text elements in ABAP. OTR's are created for
UI texts and texts can be maintained in multiple language.
OTR's can be created using the transaction: SOTR_EDIT
15) Concept of Interface Views
If the views of a different components are need to be used in a webdynpro component mark the view as
interface view and use it in another component. It's similar to using a include in a program. A Interface
view of the component can be used in any no of components. this concept supports the reusuability of
the views.
16) Sequence of Webdynpro Events:
Ex: WDDOINIT,WDMODIFYVIEW,WDAFTERACTION,
WDBEFOREACTION etc
Sequence: WDDOINIT of the component controller,
WDDOINIT of the Window Controller,
WDDOINIT of the View Controller,
WDMODIFYVIEW(On Input/Display on any UI Element).
WDBEFOREACTION(Method for validation of user input,
Once the user action happens on the UI)
WDAFTERACTION(Method for non-action specific operations
before Navigation)
WDDOEXIT( Exit from the View/Window/Component Controller)
WDPOSTPROCESSING(used to perform exception handling for supply function methods)
17) Can a Component have Multiple Applications
Yes, For a given webdynpro component any no of applications can be created. Applications are similar
to transactions in SAP. You can associate different Interface views of the component to create different
applications using the same component.

You can use Interface views to navigate between components or create a navigation class and
do a explicit call.
20) Creating a tree in Webdynpro
Tree UI element is used to create Tree in Webdynpro. Tree can be defined as part of the table column.
21) Usage of Exit Plug in a Webdynpro Window
Exit plugs are outbound plugs used to close the webdynpro application. they can be called from the view
which are embedded in the window Note: Exit plugs won't work in portal environment.
Exit plugs can also be used to pass the call to another URL. Here is the sample code snippet of the exit
plug call:
method onexit .
data url type string.
data close_window type wdy_boolean.
url = 'url_name'.
close_window = abap_false.
wd_this->fire_to_exit_plg( url = url
close_window = close_window ).
endmethod.

Iam really satisfy by your information.
It's well-written, to the point, and relative to what I do.
I like it very much for giving information on
SAP ABAP Online Training
.
Hi Christi , Scope of Webdynpro is huge and it is growing in the market every day. New technologies is also adding into it. For the topic's list , please give your email id , I will share it with you.
Excellent piece of information on sap abap, I feel it is right place to get info on SAP ABAP. This was really something, I had been looking for days. Too excited to view your other blogs on ABAP. we provide SAP ABAP ONLINE TRAINING.
ABAP stands for Advanced Business Application Programming. It is a high-level programming languages used in the SAP software for customization and other development purposes. ABAP syntax is almost similar to COBOL language. It was the first language that includes the concept of Logical Databases.
SAP ABAP ONLINE TRAINING
ABAP (Advanced Business Application Programming, originally Allgemeiner Berichts-Aufbereitungs-Prozessor, German for “general report creation
processor”) is a very high level programming language created by the German software company SAP.
