Hi,
does anybody know whether there is, and if what kind of support WDA provides for Mobile devices.
Is there Online and offline support and automatic device recognition provided?
Thanks in advance

Hi ,
The following will be helpful i guess.

Sorry, but I'm still confused. In many places here in the forum as well as in the wiki there are many commets that currently Web Dynpro for ABAP does not support any mobile devices. The presentation you mention clearly states that Mobile devices can be supported already using the Mobile Infrastructure.
Can anybody try to explain how these two statements correlate?

Hi Torsten.
Mobile Infrastructure is a completely different architecture and has nothing to do with
WD4A.
With Mobile Infratsurcture you can build mobile applications which synchronizes data
with the backend. SAP has already some custome applications like Mobile Asset
Management for Utilities which is built on this architecture.
But WD4A is not supported by PDAs. And you do not have the possibilties to write
offline applications which can be used to work in the field with WD4A. You always have
to be connected to the server to exchange data. With Mobile Infrastruture you can sync
the data and work offline with the mobile application and sync the data back later.
Hope this clarifies your questions.

Hi,
thanks for your answers. Let me explain how I have understood that:
based on SAP NW 7.0 WDA does not provide support of mobile devices, but only WDJ does supoort it.
If I want to make functionality which is implemented in JAVA or ABAP available on mobile devices, I can either use WDJ or Mobile Infrastructure. Is that about right?
Thanks for your patients

Hi Torsten.
Yes this is rite. Though I have never used WD4J I guess that you can only develop
online applications with it, so mobile devices need to have always connection to the server.
With MI you can develop offline applications based on JSP/or AWT running on the modbile device.

Okay so based on the implemented functionality I can build User Interfaces (UI)with WD.
If I want to use Mobile Devices as UI I can do that online and offline
- directly with WDJ or
- if I have used WDA I have to build UIs in the Mobile Infrastructure seperately
Is that right??
Does anybody know when WDA is supporting Mobile Devices? I heard it is planned for some time in the future?

Not fully ... I do not understand what you mean by the last point.
If you have used WDA why you should have to use Mobile Infrastructure.
Then you could transform to WDJ also.
The main usage would be:
WDJ - If you have an application that is online (PDAs are always connected like working in the plant via wireless).This could also be solved by using BSP.
MI - User are leaving the plant to e.g. delivery things offline with PDA. Then you use MI cause MI offers the sync functionality. You have a UI here which runs on the PDA and is independent.

Okay, maybe I have not made me clear.
Starting point: I have functionality developed which runs on the application server.
Requirements/Szenario: I need User Interaction ...
1. in a Portal: here I can use Web Dynpro (JAVA and ABAP) and BSP
2. with Mobile Devices (online mode only): here I can use Web Dynpro for JAVA, BSP and Mobile Infrastructure
3. with Mobile Devices (online and offline mode): here I can use only Mobile Infrastructure for
Is that right? I hope the question is now better structured and understandable)
Regards and many thanks
Torsten
P.S.: Does anybody know when the mobile support is provided with Web Dynpro for ABAP
Hi Thorsten,
I guess I did not gtive all info too.
You are right in all points except, that you would not create an online application with MI.
MI has an online server part, but this is just used for synchronisation of data.
In MI you'd develop only the UI for the offline part running on the PDA.
We had a scenarion were we needed online and offline part. We solved this by
using BSP for the online part. If the user did all necessary stuff online and was
ready to leave the plant we redirected to the locale running MI server on PDA,
synced the data and the user worked offline with MI then. When he came back to
the plant the data were synced again and the user was reduirected to the online
BSP application again.
I guess the link provided by Anzy explains in detail how MI works with all its parts.
Hope this helps.
Cheers,
Sascha
OKay
But basically today it would be also possible to use WD4J. Another question concerning an mobile scenario (online/offline).
Working with WD4ABAP wouldn't be possible to use interactive Forms whenever a Mobile Device is supposed to be integrated? In this case it would be possible to have online and offline supoort wouldn't it?
Thanks
Torsten
