Hi all New to WebDynpro for ABAP

Hi All,
I am New to WebDynpro.
I try to create an Hello world program for the first time.
I first created a WebDynpro by using SE80.
Then i created a view by right clicking on it.
but once the View was created at the Layout tab i am getting the error:
The Page Cannot be displayed.
as that we get on web browsers.
Please let me know is i have make some changes in settings.

Hi Lokesh,
Try this open the internet explorer .In the menu select tools -> internet options ->connections (tab) -> LAN settings ( Button ) -> Check the check box Use a proxy server for your LAN .
Also go to tcode SICF and choose SAP->bc->web dynpro
right click and select activate service from the popup menu.

New to Webdynpro for ABAP

Hi Experts,
I am working in Webdynpro Java and Portal Administration for the past three years.
I am very much interested in learning Webdynpro ABAP.
Please let me know what are the skills (in ABAP language especially) i need to know for working in
Webdynpro ABAP. What are the scopes in the coming days for Webdynpro ABAP.
Thanks a lot.

Dear Srini,
Welcome to Web Dynpro for ABAP forum!!!
Webdynpro ABAP is mainly for developing webapplications in ABAP.
WDA includes all the three things i.e. Programming, UI design & Settings (configuration).
As you said you have good experience of 3 yrs in Java. Try to gain some knowledge of ABAP Objects (OOP). It will be helpful to you.
There are lots of threads are available.
Plz chk the below links:

In webdynpro for ABAP alv table issue

hello gurus,
                  i am new for webdynpro for ABAP.i strucked at one point at designing time.anybody could you suggest me on this.
thanks in advance.
let me explain my scenario first.
in my webdynpro for ABAP developement i have one alv table having ten fields.i am featching the data for eight fields from one Ztabale and updating , for rest of two fields we need to fill after displaying output using the respective F4 help. Right now these two fields are in input editable mode.now i am getting the values successfully from F4 help and at the same time it is allowing MANUAL ENTRIES also but as per my requirement it should not allow any manual entries . for this i have made these two fields are in readonly mode as like as rest of fields to avoid the MANUAL ENTRIES but at this time i didnot get any F4 helpfor those two fields.
so how can i achive my goal in this thing could any one suggest me.
my final conclusion is we need to get only F4 help values into those two fields . it should not allow any manual values at any point of time.
best regards,
babu

Webdynpro for ABAP - interactive Adobe form - drop down lists not working

Hi all,
I'm trying to create an interactive form for a client using webdynpro for ABAP and I've viewed the demo "Create SAP Interactive Forms by Adobe with Web Dynpro for ABAP" by Thomas Jung, but when I implement it the form following similar steps the form is not interactive.
In the properties of the "InterativeForm", I've tried clicking the "enabled" flag both on and off. I've also tried setting the "displayType" property to both "ActiveX" and "Native". But none of this worked.
I though my problem might be with Adobe reader so I switched from 8.0 back to 7.0 but this didn't make any difference either.
The system we are using is NW04s WAS 700. Any hints would be greatly appreciated!
Thanks,
-tom

Thanks for the suggestion Dezso. I've downloaded a newer version of ACF as indicated by the OSS note and installed it. I'm still having the same issue.
My basic question is what options should I be using in the form and on the InteractiveForm component? It looks like because of the evolution of the product there are multiple options available. I recall reading somewhere that as of a certain SP level we should have ZCI (zero client install) available. The would be our preference. It will be a support nightmare if each user needed a manual download of ACF.exe installed.
Should I click the "enabled" flag on the InteractiveForm object? When I create the form should I use the "Native" drop down list or the one from the "Active X" tab? I would like to use the "List Box" control on the form as well but it is only available in the "Standard" tab. So does that mean I can't get the selections from a "List Box"?
Thanks,-tom

Webdynpro for ABAP and Workflow

Hi All,
I have few applications developed in WebDynpro for ABAP. Now I have the following requirement in one of my application. I am creating some new entries in the custom table based on the user inputs and actions. Before creating a new entry some one needs to approve that. Once the approval is done I have to create a new entry.
I came to know that this can be achieved using workflow. I have no much idea on workflow. Could someone suggest me how I can achieve that please?
Thank You,
Suresh.

Hello,
Use transaction : SWFVISU and maintain the task and the corresponding webdynpro application (parameters if any).
Register UWL with workitem handler and configure UWL.For details,

How can we benefit from WebDynpro for ABAP over Normal ABAP

Dear Guru's,
Please guide me what are +Ves of WebDynpro over Normal ABAP. Once all Applications are developed how can we organize them. For Example In SD module there is sequence of Tcodes to be executed this is true for all modules . Is there any concept involved in this new technology.
For What purpose we can suggest someone to implement in an Organization.
Many Thanks in Advance.
Regards
Ram

Hi Ram,
Here Are some comparisions I made w.r.t Webdynpro for ABAP (also some benifits over Java):
1     "Pros:it will be easier to move your development project through the system landscape if both the UI and business logic are in the same development environment.(Update: This is is less of a concern now that CTS+ lets you bundle your WD Java UI developement with ABAP development objects into a single transport, with SPS13. )
2     tons of custom ABAP business logic is easier to access via WD for ABAP
3     WD for ABAP has a code wizard, so easy to build
4     SAP List Viewer and ALV handled better
5      The biggest thing is the NWDI. Most of the SAP customer have ABAP stack, but not everyone has the Java stack. To develop WD Java you need to set up the NWDI envrionment, like SLD, CMS, CBS, DTR, etc. which is a huge effort if you don't have them in place. While for WD ABAP, the environemnt is normally there as given for most of customers if they have the right version.
6     If your business is in SAP system, I would prefer WD ABAP. There are many WD components available in WD ABAP like select-option, Alv table, F4-help which are not available in WD Java. Beside in WD ABAP you can deal the context node in form of internal table which is much more performant than dealing with the contextelement which is the case for WD Java.

Monitor usage of Webdynpro for Abap Application

Dear all,
How does one monitor how many times a Webdynpro for Abap application is called by users? We have an i-view in the portal that calls a WD4A program in the back-end system. Is there anything in the portal or back-end that will give us the usage information?
Thanks, Neeta

Hi Thomas,
We are not necessarily looking for performance data but how many times a bsp and/or function module is called. The idea is to try and determine how many calls are made to SWN_WIEXECUTE BSP via a URL (http://<hostname>:xxxx/bc/bsp/sap/SWN_WIEXECUTE/MAIN.DO to track a usage of a new workflow approval/rejection process.
We also want track how many calls are made to SAP_WAPI_WORKITEM_COMPLETE function module to track approval/rejection of a workflow process via Portal UWL.
Best Regards, Neeta

Portal using Webdynpro for ABAP

Hi Gurus!
    I am using one portal using 'Webdynpro For ABAP'. It contains Contextual Panel as well as ViewUIContainer. Contextual Panel contains all the reqd options available for user; while ViewUIContainer contains diff views as requested.
   Now, I'm trying to make a copy of that Webdynpro with some other name. What happens is --
Application is not there and when I try to make one - it says
"Interface View Does Not Exists."
Further, when I try to make an Interface View with the new name - it says
"Interface View Does Not Exists."
   Therefore, what I could conclude about the case is -- may be Interface View is default to certain Webdynpro components/interface. Hence, my question is how can I make use of same webdynpro application with some other name. This requirement arises due to the fact that we have to add some more functionalities to that and I dont want to play with the efforts made so far.
Kumar Saurav.

Issue Resolved.

Web Dynpro ABAP
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/db22242d-0701-0010-28a2-aeaa1fefd706
Hope that the following also helps you.
Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web
applications in the ABAP environment. It consists of a runtime environment and a graphical
development environment with special Web Dynpro tools that are integrated in the ABAP
Workbench (SE80).
Web Dynpro offers the following advantages for application developers:
The use of declarative and graphical tools significantly reduces the implementation
effort
Web Dynpro supports a structured design process
Strict separation between layout and business data
Reuse and better maintainability by using components
The layout and navigation is easily changed using the Web Dynpro tools
Stateful applications are supported that is, if the page is changed and the required
data remains intact so that you can access it at any time throughout the entire
application context.
Note that stateless applications are not possible.
Automatic data transport using data binding
Automatic input check
Automatic operation of the Web Dynpro application using the keyboard
User interface accessibility is supported
Full integration in the reliable ABAP development environment
Web Dynpro Architecture
Definition
Web Dynpro is the SAP NetWeaver programming model for user interfaces (UIs).
The Web Dynpro model is based on the Model View Controller paradigm, and has the
following features that build on the classic dynpro model:
Clear separation of business logic and display logic
Uniform metamodel for all types of user interfaces
Execution on a number of client platforms.
Extensive platform independence of interfaces
Structure
Metamodel Concept
Web Dynpro provides support for developing Web representation of a business application.
You use specific tools to describe the properties of a Web Dynpro application in the form of
Web Dynpro metadata. The necessary source code is then generated automatically and
executed at runtime. In addition to the events offered by the framework, you can also define
your own events for a Web Dynpro application. However, the event handling must always be
programmed in separate source code areas which are executed automatically when the event
is triggered at runtime.
In Web Dynpro, each user interface is always made up of the same basic elements. These
elements of the metamodel can be statically declared using Web Dynpro tools.
It is also possible to implement elements of the metamodel at runtime and to change them or
reintegrate them at runtime. Using these implementations, you can make any changes or
enhancements to a user interface that has been created by declarative methods by
generating new interface structures at runtime.
This means that you can combine declarative processes and the implementation of source
code.
Graphical Development Tools
To support this declarative concept, both the SAP NetWeaver Developer Studio and the
ABAP Workbench contain a range of Web Dynpro tools. You can therefore generate a large
proportion of a Web Dynpro application using the tools provided, without having to create your
own source code. This applies to the following parts of the application:
Data flow between the front end and back end
Layout of the user interface
Properties of user interface elements
The Web Dynpro tools enable you to create source text areas manually within generated
source texts. These areas are not changed if the source code is regenerated.
Separation of Business and Application Logic
Using Web Dynpro enables a clear separation of business logic and display logic. A Web
Dynpro application runs on the front end and has local or remote access to the back end
system via a service. This means that the display logic is contained in the Web Dynpro
application, while the business logic and the persistence of the business objects run in the
back end system. The following options are currently available for connecting Web Dynpro
applications and the back-end system:
An interface generated using adaptive RFC, through which BAPIs of an SAP system
can be called
An interface for calling Web services
A self-generated interface
The source code required for connecting the Web Dynpro application can be generated
from a UML definition of the Web Dynpro interface. A UML definition can be imported
into the Web Dynpro tools as an XML file.
Conversion of the Model-View-Controller
Conversion of the Model-View-Controller Programming Model
Every Web Dynpro application is structured according to the Model View Controller
programming model:
The model forms the interface to the back end system and thus enables the
Web Dynpro application access to data.
The view is responsible for the representation of the data in the browser.
The controller lies between the view and the model. The controller formats
the model data to be displayed in the view, processes the user entries made by the
user, and returns them to the model.

Webdynpro for ABAP materials

anyone please send me materials for webdynpro for abap which covers webdynpro architecture like mvc controller and everything

Hi Ganesh,
Welcome to Web Dynpro ABAP !
In web dynpro ABAP we follow MVC(Model View Controller) architecture.
In this object oriented ABAP is used to provide background functionality. Here, your ABAP skills can be utilized to the fullest. Programming in web dynpro ABAP is different than conventional ABAP programming. Here we strictly follow MVC architecture in terms of controller interface. Also there are many wizards available so that we can directly pick the code from wizards.
e.g We can call BAPI through a service call in web dynpro application. Thus automatically backgroud code for BAPI execution will be generated.
To start with Web dynpro ABAP you can try following tutorial:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a282c952-0801-0010-1eb5-87953e036712
You can start with tutorials and all. There are around six tutorials in SDN library.
Web Dynpro for ABAP
http://help.sap.com/saphelp_erp2005/helpdata/en/a5/1a1e3e7181b60ae10000000a114084/frameset.htm
best tutorials in wbdynpro for ABAP to start with :
https://www.sdn.sap.com/irj/sdn/developerareas/webdynpro?rid=/webcontent/uuid/fed073e5-0901-0010-4eb4-c9882aac7b11 [original link is broken]
1) This is basic Info of WD ABAP
As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.
2 ) I can give you links that can help you a lot.
First of all start doing SAP SDN tutorials .
Create some compenents with BAPI , Component usage and ALV .
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/02e1fa45-0801-0010-10a0-f1cf47e8c943
/people/marilyn.pratt/blog/2005/12/20/web-dynpro-for-abap
Try to Download demo tutorials from SDN library & Try to search WebDynpro ABAP WebLogs .
Also, SAP has provided you with ample demo example of WD ABAP already bundled with SAP . Just Try out Components starting with WDR . I can tell you few like WDR_TEST_EVENTS ( It shows how every UI elments to use )
See packages like SWDP_DEMO , SALV_WD_DEMO
there are many more .
Hope I have helped you .

Comparison between WebDynpro for ABAP vs. WebDynpro for Java ??

Hi,
Can someone tell me when should we go for WebDynpro for ABAP and when WebDynpro for Java. Is there any link where SAP recommends the one for the other.
Thanks in advance
Regards
Mukesh

Hi Mukesh,
Both are having its own strengths!! )
I think it all depends on your project requirement and the availabel resources.
If the developer is good in OOPs ABAP then he must go for Web Dynpro ABAP. But if anyone is good in JAVA then that person should go for Web Dynpro JAVA.
*In Short almost all Features supported in webdynpro ABAP are also Possible in webdynpro Java.
1] Webdynpro Java
Supports,
webservice
RFC Models
Accessing Portal information in Java
Easy sending E-mail
Strictly follows MVC architecture which seperate Business logic and Process flow.
Webdynpro Java is webbased programming model to develop SAP Applications.
Easy to learn
Easy to integrate in Enter prise portals.
Dynanamic Programming
*Easy access to R/3 Via RFC technology (Models)
2] Web Dynpro ABAP
As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java.

The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.
Hope this helps and solve your Problem
Cheers,
Darshna.
