Navigation among iview of WebDynpro for ABAP

Hello Friends,
I would like to know, if Object Based Navigation is possible in ABAP stack, if yes, how ? would be nice if some one direct me to some good resource.
If OBN is not possible what are other ways, of doing navitation ( navigation among ivews and abap application, it means form one iview when calling other iview I could be able to pass the object ref so that in called ivew ( 2nd ivew ) I can retrive the corresponding information).
I came across an artical where its only mentioned that OBN is supported with both JAVA and ABAP stack, but did not find enough details to the topic.
One another thing which I saw was, there are inbound and outbound plugs for navigation ?? still did not get enough details.
Thanks for the kind inputs,
Regards,

Hi Shah,
Portal navigation can be triggered by using interface IF_WD_PORTAL_INTEGRATION. It can be obtained by calling GET_PORTAL_MANAGER of IF_WD_COMPONENT. This interface can be obtained by calling wd_get_api() at wd_this of the ComponentController. Regarding the usage of the IF_WD_PORTAL_INTEGRATION interface, there is some documentation available in the help portal. A quick google search revealed <a href="http://help.sap.com/saphelp_erp2005/helpdata/en/0e/a1e94205045604e10000000a155106/content.htm">http://help.sap.com/saphelp_erp2005/helpdata/en/0e/a1e94205045604e10000000a155106/content.htm</a> as the one to look at.
Best regards,

WebDynpro for ABAP iview

Hi All,
In my client portal there is no iview template of type "SAP WebDynpro iview" .
I created one from the list of PAR templates of type com.sap.portal.appintegrator.sap.WebDynpro
and embedded it in a webdynpro proxy page
i have given the following parameters.
Application
Application Namespace
configuration name
platform 'webdynpro for ABAP'
WebDynpro client 'plain HTML'
system
But at runtime when i login with the end user it gives a blank page.
Please advise.
Thanks,
VV

What happens when you try to test the same application you put in the iView from SE80. Sounds like the developer of the application might have forgotten to embed their default view in the window. A very common mistake on older support packge levels before the workbench started embedding the default view automatically.

Who can tell me how to find the leave request Webdynpro for ABAP iview

Hi,Expert,
As I know Portal only has Webdynpro for java iview for leave request iview in the past.
but someone tell me SAP portal has delivered some new standard WebDynpro for ABAP iview.
I have a requirement to create a employee role for new Leave Request service created by WD ABAP . Under Content Provided by SAP in Content Administration, I couldn't find the iView assocated to the leave request except the Java one. Is there have any Employee Self-Service Web Dynpro ABAP workset ?

Olivia

The business package for ESS based on Webdynpro for ABAP is available only for ECC 6.0 EHP5.
If you are on EHP5, you may choose to use this version of the BP.

Need to create a Calender in WebDynpro for ABAP

Hi,
Tcode SSC1 displays owner's calender. I need to create same calender in WebDynpro for ABAP. I couldn't find any standard component usage for the same. Is there any component usage for the same or is there any altenative to create the same?
It's quite urgent.
Thanks,
Mahesh

Hi
You have to use DateNavigator Control to get the left hand side screen in SCC1 and
for the right hand side one you have to work with table Control
for Date Navigator UI control see WDR_TEST_EVENTS
and to get the right hand side screen see WDR_TEST_TABLE see the view SingleMarkableCell.
Using both these standard components you can achieve this.

Webdynpro for ABAP - Popup apearing for userid and pwd

Hi Experts,
We have implemented ESS and gone live. Now we have created one custom application in webdynpro for ABAP and attached with portal.
Initially there was a problem, the application was not getting executed because of system configuration, then I have configured the host name, port number correctly. Then the iView is getting loaded in the portal.
The problem is, when I am trying to access the iView, the popup apearing for the user id and password. This is happening only the webdynpro abap application, this is not happening for all sap standard iViews.
Could anyone help me with this issue?
Thanks
Jay

Hi Jayanthi,
as you had mentioned this is not happening for sap standard iViews(do you mean simple transaction iViews for which you have used a system alias, which was the same you had used for ABAP web dynpro iview)?
Of courese ESS iViews works with their own JCOs which is no way helpful or connected with wd ABAP.
So I believe if your SAP id and Portal id are different(or if they are same but SAP Logon ticket is not configured properly) then only it woudl ask for the authentication again- for Wd ABAP to work fine, only the connector property and WAS to tbe configured in the system object(aka system alias) used for ABAP iview. Now once you enter the login credentials, it is working fine right, then could you please test the user mapping under the user you are logged in, select the alias that you had used while creating the abap wd iView and provide userid/password here, then run the wd ABAP application, it definitely would work.
N.B: if you had provided the credentials once, then it woud be stored in the browser cache, so if you perform the user mapping in user admin, log off from portal, close all your browser windows, then clear cache,(cookies etc). then login to portal, run the wdABAP application, I am sure this would work(it worked for me!!!).
Thanks,
Jakes.

How to integrate WebDynpro for ABAP application with SAPEnterprisePortal7.0

Hi WebDynpro for ABAP Experts,
We developed an WebDynpro for ABAP application on R/3, and now we are planning to show this as an iview on SAP Portal EP7.0 (SAP j2EE Engine--Java stack). is it possible to integrate this application with portal?
If so can you proviode me the way how can we achieve this?
ADV Thanks
Regards
Phani

Hi Alex,
Thanks for your response.
I already created the system object R/3 Backend.
Actually some WebDynpro java applications/iViews are currently running on Portal. and the developers developed these in NWDS and deployed the .sca files on the Portal server and we created Webdynpro for java iViews.
but now the requirement is creation of webDynpro for ABAP views.
The developers developed WebDynpro for ABAP on the R/3 system. So what are the parameter values we need to give at teh time of creation of WebDynpro for ABAP iview like the Namespace, Application name etc which are mandatory values and how the Portal server detects the application, this means no need to deploy the application on the Portal server?
Shall we need to maintain any JCo Destinations or not?
Pl share your ideas.
ADV Thanks

Phani

Webdynpro for ABAP and Portal Integration

Hi Experts,
we created a WebDynpro for ABAP application for portal. The application will modify/update few fields in backend sap HR table PA0006 (infotype 6) . The end user (portal user) should be able to update his data in backend with the iview created on this application.
I have below two questions in my mind.
1. Do we need portal eventing for this? It's a single iview in portal which will fetch and update his data through this WebDynpro for ABAP application.
2. It is for 10 countries of almost 1000 users (with same userid in portal and backend). How can I make sure that the enduser updates and fetch his records only. The SSO is already set up between Portal and Sap ECC system. Do I need to again pass the enduser portal id to the sap in coding to fetch and update the data or sso will take care of itself.
Thanks
Ajay

1. Do we need portal eventing for this? It's a single iview in portal which will fetch and update his data through this WebDynpro for ABAP application.
Answer: If you use, for exemple ITS to access this Webdympro, you will not need any action on portal for sure. Actually you will just need actions on portal, if you want to make some customization on portal side. If you want just show the Webdympro how it is, your action are all on backend..
2. It is for 10 countries of almost 1000 users (with same userid in portal and backend). How can I make sure that the enduser updates and fetch his records only. The SSO is already set up between Portal and Sap ECC system. Do I need to again pass the enduser portal id to the sap in coding to fetch and update the data or sso will take care of itself.
If you access via ITS, te custome will acess the backend with the user you have set on the SSO or user-mapping. The portal there is nothing to do in this regards, you must just take care of this on backend.
Please evaluating the answer you are contributing for the SDN keep growing.

Can we determine the CAPSLOCK is ON in a webdynpro for ABAP application?

I have a pwd field in a Webdynpro for ABAP application. If the CAPSLOCK is on then I need to prompt user either via popup or a static text on the page that "CAPSLOCK is ON". Is there way a to determine the caps lock is on when the user enables CAPSLOCK? Thanks for help in advance
Regards,
Madan.

Thank you for your response. I am already prompting the user if the pwd is incorrect. But user is expecting to receive a prompt if the CAPSLOCK is ON to avoid typing incorrect pwd. If it is not possible to identify whenever the CAPSLOCK is turned ON, atleast is there a way to identify the CAPSLOCK is ON whenever user is navigated to this page/webdynpro application.
Regards,
Madan.

Eventing in Portal page between Team Viewer and Custom Webdynpro for ABAP

We are trying to implement a new Portal page that contains a Team Viewer Iview and a custom Webdynpro for ABAP iview.
The idea is that the when a manager select one of his direct report in the Team Viewer, the custom Webdynpro for ABAP would pick up the selection_changed event and retrieve the data for the selected employee.
We followed the instruction provided by SAP in note 1112733 and it worked in our development environment. When we moved the iviews to our testing environment it stopped working.
I also used the Diagnostic Iviews provided by SAP and I get the same result: Works in Dev, does not work in QA or in Prod.
We also followed the troubleshooting steps of note 945516 and it still did not help us. We can not find a difference in our system set up.
We are therefore looking for pointers as to what could be our problem.
Thanks!
Edited by: Benoit Fortin on Feb 20, 2009 2:28 PM

Problem was solved internally:
The reasons the eventing worked in Dev and not in QA or Prod, was that we had a different level of patch for ESS/MSS between instances, which I was not aware of.
Dev was on ESS/MSS version 600 SP14 and QA and Prod was on a different level. Once we implemented ESS/MSS SP 14 accross the board, everything was good.

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.

How to create a node with attributes at runtime in webdynpro for ABAP?

Hi Experts,
         How to create a node with attributes at runtime in webdynpro for ABAP? What classes or interfaces I should use? Please provide some sample code.
I have checked IF_WD_CONTEXT_NODE_INFO and there is ADD_NEW_CHILD_NODE method. But this is not creating any node. I this this creates only a "node info" object.
I even check IF_WD_CONTEXT_NODE but i could not find any method that creates a node with attribute.
Please help!
Thanks

CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition

Follow-up webdynpro for abap using portal theme nw2004s, sp12

Hello,
I wanted to get a follow up to this thread,
Re: webdynpro for abap using portal theme nw2004s, sp12
We are having a problem with the way reports developed in Web Dynpro for ABAP displayed in the portal (the pop-ups and dropdowns look out of wack). The issue appears when we wrap the reports into portal themes (either standard or custom). As per the thread (the link for which I posted above), the suggestion was to apply WDFORCEEXTERNALSTYLESHEET parameter to the WDP, however our system doesn't have this parameter in the system, but it seems like I can create my own parameter. Can some on give me all of the properties assigned to WDFORCEEXTERNALSTYLESHEET in table WDY_APP_PROP_DEF.
Thank you

Hi Brad, I was trying to apply the note 1033496 but our ABAP servers does not have the WDFORCEEXTERNALSTYLESHEET parameter available in WDY_APP_PROP_DEF table. All other notes are not applicable to our issue.
The portal is NW2004s SP12, the ABAP server is NW2004 SP11
Regards.
