Time Trigger in Web dynpro

How to use time trigger in web-dynpro without refreshing the page?
If it's not possible then is there any alternate way to run a timmer in an web-dynpro application?

HI,
You can use "TIMED_TRIGGER" UI elemant provided by WebDynpro. You can Bind Delay property to the interval of autorefresh.
Please use below link for more information.

Time outs in Web Dynpro

Hi,
How does SAP applications handle sessions time outs in Web Dynpro for ABAP when the processing takes a long time. Can we change some configuration settings so that we can have a Web Dynpro application can run for a very long time without getting into time-outs?

WDA uses a Dialog Work Process just like a SAPGUI session and is subject to the same timeout limit on continuous processing within this work process.
In addition there is also a separate timeout parameter at the ICM level. This controls how long the HTTP connection is held open while wiating on the Diag Work Process to complete its work. The ICM time out is generally set shorter than the dialog WP timeout - default is set to 60 seconds.

Real time scenarios where Web Dynpro is used

Hi Experts,
I am a beginner with Web Dynpro (ABAP ), i have developed a couple of simple web dynpros for practice purpose. I would like to know the below things to get a better idea on the technology
1. Can anyone who have worked on Web Dynpro share the real time applications which you worked on.(I am not expecting any technical details, i want to understand the scenarios in real world where this technology is used).
2. If some one can link web dynpro's with CRM/SRM that would help me more.(Once again i need the business scenario)
Thanks in advance.

Hi Sharath,
Thanks for your response, it was really a useful link. But once again they all talk about technical details but what i was looking for was business scenarios where web dynpro can be used effectively.
When i was searching for this i found one such scenario where web dynpro gets the quotation details from the CRM system and creates a sales order with reference to the quotation in the SAP R/3.
I was actually looking for scenarios like the above with some technical details for implementing the same.
Please let me know if you know scenarios something like the above one.Thanks.

Time estimation for Web Dynpro development

Hello all,
i would like to know if someone could tell me how much time do we have to estimate when using web dynpros to recreate R/3 transactions (with the convert tool) ?
In fact we must make an offer for a customer and would like to use Web Dynpros (since this customer wants that all developments are J2EE based and not related to R/3).
Since we don't yet have any experience with this, it's not easy to make an estimation of the effort that it would take.
So if you know what is the average time to make an R/3 transaction Web Dynpro enabled, please let me know.
Thank you in advance,
Xavier

Hi Xavier,
what i know so far about the convert tool is, that it allows to convert classic ABAP dynpros to Web Dynpro, but not between the ABAP Web Dynpro runtime and the Java Web Dynpro runtime.
Among other things, the PAI and PBO modules of the classic dynpro are reused including possible input validations which may directly access some tables of the ABAP dictionary.
Since all these things are not at all directly accessible by Web Dynpro for Java and the J2EE engine in general, the only thing, that might be transferrable IMHO is the layout information (buttons, inputfields...).

Excessive Time to launch Web Dynpro iView

Hello,
I have an interesting problem here: When I launch the web dynpro Java iView in Portals 7.0, its taking 5-6 seconds to launch the iView. After that its calling the web dynpro application. I couldnt understand why there is such delay?. Has anyone experienced this kind of problem?.
If you have any suggestions, please let me kow. I appreciate your help.
Thanks,
Raj Peddisetty.

Yogesh,
I am not making any RFC calls or JDBC Calls. Yet it is taking around 6-7 sec to launch.
Any idea on how to reduce this?.
Thanks,
Raj Peddisetty.

Context not updated from adobe from fields to ABAP web dynpro every time

Hi,
I work through a turtorial for interactive adobe form in web dynpro. The turtorial link is as following:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/media/uuid/c766e918-0b01-0010-99b1-c2b78cd059b3?prtmode=navigate
I use Active X adobe form display type and submit button. Basically, it works.
My problem is the 1st time I change the out_amount in adobe form and click 'Submit'. Everything OK. The corresponding context field in Web Dynpro is updated and showed in my own web dynpro field.
Then, I change the out_amount again in Adobe form and click 'Submit' again. The context is not updated.
The interesting thing is when I click 'Submit' the 3rd time, it works again. Same situation happens for 4 and 5 times click 'Submit' and so on.
It seems I need to click 'Submit' two times and the web dynpro context is then updated.
Is there anyone have any clue about my problem?
Thank you in advance!

Please provide the solution.......

Automatic time zone conversion in web dynpro

We have a WDA running on top of a SAP system that is running on US time. The data from the WDA must be stored in SAP using US time. The WDA will however run in England and needs to display English time to the users. Is there any mechanism or concept in web dynpro that provides automatic time conversion when reading from and displaying time and when writing data back to the database? Some kind of screen exit or other?
I am not asking how to convert the value of a single field from one time zone to another, I am hoping for some general solution to the problem of time zones in web dynpro.
Thanks!

I don't really have anything useful to say, but couldn't help to add my two cents here...
Whenever you work in a system that supports users or other parties spread among different time zones you start wishing for some better time zone support. It's not just the user's time zone that is relevant, just imagine for example a service call to a call center in India, where probably the customer's time zone is even more important than the user time zone.
I know that in principle we have some design issue here, because standalone dates (without any time details) are impossible to convert among different time zones. It would be nice though if the system would provide a framework where any date/time fields can be registered and linked to some time zone field. Changing the time zone field, would automatically update all registered date/time fields.
Ideally the field for choosing time zones would have the ability to show a list of preferred time zones with (changeable) explanations. One could for example imagine that by default it's populated with the two entries for user time zone and system time zone. Each application should be able to register additional time zones, e.g. sold-to time zone for an order, etc.
Another (workaround) option I used in applications (for automatically filled read-only fields, like creation date/time) is to settle on one reasonable default time zone (e.g. user) and then have tool tips showing dates/times in other relevant time zones.
Anyhow, lots of half-baked gibberish, essentially I just wanted to say that it would be nice to have some better time zone support, so I'm voting for that as well (good point Chris). And ideally this would not be limited to web dynpro. I'm sure some smart person should be able to come up with something nice...

Notification Service in Web Dynpro for Java?

Hello Experts,
I'm new on the topic "web dynpro for java" and have a question about a real-time-notification of web dynpro clients.
In web dynpro for abap ther is apparently a new solution called "Notification Service" (since NW 7.0 Ehp2).
Details: http://www.sdn.sap.com/irj/scn/elearn?rid=/library/uuid/f0802995-3433-2c10-2787-d7db51352891&overridelayout=true
But I found no hints how to solve the problem of a real-time notification in web dynpro for java.
Requirements for short: The server can trigger a refresh in one or more web dynpro clients.
Requirements a liitle more extended:
1. A web dynpro is running in a browser and shows data it gets from a DataBase table1
2. Now a function module1 is started by an event and changes the data in table1 on the server side, the web dynpro does not know about this event or the changes made by external components.
3. These changed data should be visible immediately in the running web dynpro after the event occurd --> trigger a refresh of the web dynpro from the function module1?
All I actually know is that: The web dynpro can update its context with the new data from table1 after a refresh of the gui (wddomodifiyview). Using a timed trigger I can get new data after x seconds (same way --> context update and gui refresh). Is there another way to refresh the web dynpro (that noticed requirements of #3) ?
Regards,
Anja Hormann

I recommend that you create another Web Dynpro application with this Timer to execute an RFC. This application would be in a Web Dynpro iView hidden from your SAP EP and shoot an event that would be captured by another application.
However I would take great care with this type of application.
And to answer your question at the moment, to my knowledge, there is no solution for this kind of integration between the ABAP and JAVA.

Angelo

Web Dynpro component - Flat file upload

Hi,
We have a requirement to upload a flat file to Planning cube (real time cube) through Web Dynpro component.
Web Dynpro component which we have developed is able to read the records from the flat file.
Now, the issue is u201CHow can we save the records read from the flat file to planning cubeu201D?
If anyone has worked on the similar requirement, pls reply. Thanks in advance.
Note : We have a planning sequence which will be executed on the click of UPLOAD button.
This planning sequence has a filter on Infoprovider (cube which we are using for planning) and a planning function of type u201CFile uploadu201D in which we have defined the flat file format.
Aggregation level is made on Multiprovider which has 2 underlying cubes (One is realtime and other one is standard).
Is there any function module in which we can pass the name of the flat file so that it will be uploaded in planing cube?
Regards,
Ankur

Web DynPro Versioning

Hi,
I'd like to know if there is a system to include in the HTML of the web dynpro a comment in which to put in a number or string that represent the current version/changeset number/last modification date of the web Dynpro.
I need this "trick" because sometimes the transport of the activities does not go as expected and Web DynPros are not properly updated. Sometimes the changes between two consecutive versions are not GUI changes but code changes and there is no way to see at a glance if the transport completed successfully.
Any ideas how to do this?
Thank you,
Pietro

Hi Ajay,
if Netweaver keeps track of the current build number (i.e., a version number that is incremented by 1 every time the Web DynPro is built) and stores it as a special readable property or even as a number written in a plain text file, it still will be possible to read and display it. The important thing is that this number is incremented automatically by Netweaver and that is indicative of the "current version" of the Web DynPro (i.e. the 276-times-built Web DynPro is an older version in respect to the 321-times-built same Web DynPro).
So if I transport version 222 and then I build the WDP three times locally and transport it again, the "build number file/property" now reads 225 and the method embedded in the code is still the same ("read the number in that file/property and show it").
I hope that explains what I meant.
A number like that, if Netweaver uses or creates it, is the simplest way to see what "version" a Web DynPro is. Alternatively the last build date should do the same trick. The problem is that I need to get, in the code, some sort of "marker" that Netweaver uses to keep track of the version of the Web DynPro.

Pietro

also go through the following
Using the FunctionKey
Use
The FunctionKey allows you to trigger a Web Dynpro action using a specific key on the mobile device. In the following example, this UI element is used to navigate to another view via a specific key.
Prerequisites
●     The SAP NetWeaver Developer Studio is installed on your computer, and you can use it to create your mobile Web Dynpro application
●     You have access to a SAP NetWeaver Application Server, where you are running the Web Dynpro application
●     You are using a Pocket PC with special scanning equipment manufactured by Intermec Technologies or Symbol Technologies
●     You have created two views in a Web Dynpro project and called them StartingView and TargetView.
Procedure
       1.      Navigate to the StartingView and double-click the view or choose Edit from the context menu.
       2.      Insert the mobile UI element FunctionKey.
       3.      Switch to the Plugs tab, create an outbound plug with the name fromFunctionKey and define the navigation link to the TargetView.
       4.      Switch to the Actions tab page and define an action called NavigateToAnotherView.
       5.      Assign the value IBrowse_OnKey49 to the keyCode property of the FunctionKey.
       6.      Assign the NavigateToAnotherView action to the onAction event of UI element NavigateToAnotherView.
       7.      Switch to the Implementation tab and add the following source code to the implementation of the view controller. The read data is passed to the context and the relevant context attribute is set.
public void onActionNavigateToAnotherView(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
   //@@begin onActionNavigateToAnotherView(ServerEvent)
   wdThis.wdFirePlugFromFunctionKey();
   //@@end
Result
By pressing press key 1 on the mobile device, you navigate to the TargetView.

Call ESS FPM CATS Working time application from non FPM web dynpro application on click of button

Hi,
My requirement is to launch ESS Working time application HRESS_AC_CATS_1 from custom web dynpro application.
ESS CATS working time application is configured in LPD_CUST launchpad.
I tried using method cl_hr_navigation_services=>navigate in my custom web dynpro but it did not work.
Regards,
Ibrahim

In case you want to use Launchpad, you can use ABAP class CL_APB_LAUNCHPAD_API. If choose not to use Launchpad, you can use method CONSTRUCT_WD_URL of ABAP class CL_WD_UTILITIES to generate the URL. Specify Web Dynpro application and Web Dynpro Configuration as parameter. Finally create an external window using method CREATE_EXTERNAL_WINDOW that points to that URL.
