Trigger Automatic Search Help in WebDynpro for ABAP

I have a WDA application for creating a Purchase Order. The first screen has 2 options - one for creating a PO from scratch; and one for copying an original PO.
The second view ('Copy PO') for copying a PO has a single field (PO document) with a Search Help attached (freely programmed). The Search Help works well.
Now for the question:
When firing the second screen ('Copy PO'), I would like to trigger the Search Help without actually entering the view. Is there some way of firing an event that triggers the Search Help without entering the 'Copy PO' view?
Any help would be gratefully accepted.

hi gareth.......
            a solution for you.....
               instead of triggering a search help....
              in you wddoinit method... call a popup which ahs a table with all the required values...
             so when the user selects one... it has to be bound to an attribute....
             which is then passed to the po field.

Hi,
You have the on_save event in the Office Control. This event will be triggerd when you press ctrl+s or press the save button.
see the help here
[https://cw.sdn.sap.com/cw/docs/DOC-45207|https://cw.sdn.sap.com/cw/docs/DOC-45207]
on the event handler you have the changed copy of the document available in your context attribute of type xstring.
You can use the put method mime-repository like Abhi described.

Great article. I also had this probelm a year ago. My problems questions are:
Is it possible to select more then one entry in the tree?
What about selecting all childrens with one click?
In my solution I inserted this tree, into a table and the table had a checkbox, row, so the user can check the required org units, (more then one) and there was a separate button, for "select all children"

How to create an editable table in webdynpro for ABAP? Help!

Hi Experts,
I have a requirement where I have to create a webdynpro for ABAP table for new row/rows entry, delete row/rows and update row/rows data. This is something like table control in normal ABAP.
how can I achieve this? Is there any such feature in ALV component?
Any code sample will be really helpfull.
Please help!

Clear error message on F4 standard search help in webdynpro abap

Hi Gurus,
We have a check on the data entered by the user in our webdynpro producing a error message if the data are not correct. My problem is that this message is also diplayed in the search help afterwards when the user clicks on the search help. I know how to clear an error message but I can't find the event triggered by the F4 search help to put my code. The search help is a standard search help and thus I can't modify it.
All I want is to find the event triggered when the user clicks on the search help. The field is in an alv but the alv click or alv action are not triggered when the user clicks on the search help.
Thanks for your help in advance guys.

Yes. It is called a Freely Defined Value Help if you want to have complete control of the UI that is displayed in the dialog:

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.

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 .

/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 .

Webdynpro for ABAP vs WD for Java

How different is WD for ABAP from WD for Java?
I have a good knowledge of WD for Java and I know ABAP. But how good and efficient is WD for ABAP? Would it be better to use WD for ABAP or WD for Java for SAP based portal development?
Thanks in advance,
Reena


1. We can embedd the Web Dynpro for ABAP applications in SAP screens in ABAP environment. I don't think it is possible using java web dynpro.

Yes, you probably can, since the application can be fired simply by a URL, there is not reason that you couldn't have an HTML control in your dynpro and point to this URL.
To answer the original question, the development model for each is pretty much the same, just two different flavors. I think that some things make WDA better, one being that it is totally integrated into the ABAP development workbench and the Transport/change control system. On the WDJ side, you development locally and "deploy" your changes using the DTR and CBS. I'm not exactly comfortable with this quite yet, which is why I like WDA better..
Another thing is that we have some built in stuff with WDA, like automatic search help functionality, ALV Grid, and Select-option functionality. I do believe that SAP is working on some of these for WDJ.

How to create an elementary and collective search help in webdynpro

Hi all,
my requirement is i have to create an collective search help. and that should be same as other tcode search help functionality.
and now the ztcode is in r3 system and my webynpro development is going on bw system how to copy that tcode from r3 to bw system. and then for my input field is cost center and for this input field i should create the search help functionalty.kindly help me how to achieve this functionality i am new to this webdynpro so kindly send me the detail steps.
Thanks & Regards,
Naveen

Hi Naveen,
There's no difference to using a collective search help or a regular search help.
in the attribute of the context that you want the search helps to appear for - specify that the input help is of type dictionary search help, then specify that the input help is your collective search help.
Search helps in WDA, if search help is available at dictionary level, no need to create any search help, you get automatically.
If you want to create search help for any input field, another option is using OVS. we have WDR_OVS component for search helps, you need to reuse this component in your custom component, just change some coding according to your requirements you get search help.
Go through these documentation and helps...

Web Dynpro ABAP

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.

What is used for WebDynpro for ABAP?

hi all friends,,
what is used for WebDynpro for ABAP?
Thanks,
S.Suresh.

Hi
Web Dynpro for ABAP - Getting Started
Web Dynpro for ABAP is SAPs new standard UI technology for developing user interfaces in the ABAP environment. In the long term Web Dynpro for ABAP will be the successor of the traditional screen (Dynpro) based user interface technology which is based on the SAP GUI. Available with NetWeaver 7.0 (2004s) Web Dynpro for ABAP provides the same declarative UI development paradigm as Web Dynpro for Java directly out of the NetWeaver ABAP Application Server. Web Dynpro for ABAP allows the development of user interfaces directly within the ABAP Workbench (SE80) and the Web Dynpro runtime environment is a central part of the ABAP server and can be used in any SAP solution based on NetWeaver 7.0 (2004s) without the need of an additional server installation.
Web Dynpro for ABAP allows the development of user interfaces in a declarative way by providing a mighty framework which abstracts the rendering technology from the core UI definition tasks. The Web Dynpro developer declares the layout and behavior of the UI without caring about HTML, JavaScript, browser specifics or the HTTP protocol. Instead the focus lies on designing graphically Web Dynpro components based on the Model View Controller model, which enforces a clear separation between the UI layer and the underlying business logic.
This declarative Web Dynpro programming model enforces the developer to focus on the tasks of
Designing the layout of the visible views (where should the table be placed, do I need tabs, how should the button look?)
Declaring the flow and behavior of the application (flow between views, which event is triggered by which button click, etc)
Defining the data binding (which internal table is displayed in a specific table, etc)
Implementing the event handlers and controller methods.
Without making any assumption about the used rendering technology, like which browser should be supported or if the Web Dynpro application will be later displayed in a web browser via HTML at all or in another kind of client with completely different rendering capabilities.
The Web Dynpro Frameworks provides all important UI features directly out of the box:
All elements (tables, buttons, trees, dropdown list boxes, etc) necessary for state of the art user interfaces are provided by the Web Dynpro Framework in the form of predefined UI element libraries.
Complex features and behavior of UI elements.
Internationalization of the UI. All visible strings in a Web Dynpro ABAP UI are handled by the translation system and are translated in the same translation environment like other ABAP language dependent resources. All texts are displayed automatically at runtime, dependent of the users credentials.
Accessibility features are directly built into the framework and UI elements.
A unified rendering engine generates at runtime the data which is sent to the specific client application, which is not limited to browsers but includes the NetWeaver Business Client.
All this is available in the established environment of the ABAP application server and well known capabilities like the transportation and change management system, security environment, test and performance analysis tools or remote debugging can be used like in common ABAP development.
