Display attachments through WebDynpro Abap

Hi all,
I am currently working on the Generic Object Services and I manage to create attachment and retrieve them. however I can't find how to display attachments into a WebDynpro interface.
The context:
I have two applications which communicate with RFC:
- The first application is the business application. It contains some RFC functions to handle data, business objects and attachments. This application is under SAP R/3 4.6.C environment and attachments are stored via GOS linked to standard transactions (VA03 / CV03 / IW53).
- The other application is a WDA interface for the final users which calls, via RFC, the functions implemented in the first application. This application is under SAP R/3 ECC6.0 environment.
The goal:
I would like to implement the possibility to display some documents (PDF, DOC, XLS) stored with GOS in the first application (SAP R/3 4.6.C) via the web application (SAP R/3 ECC6.0). To do this, I will use RFC functions but I don't know the functions/methods I have to call to perform this process.
Does someone know the information that I need? Please do not hesitate to ask me should you need further information.
Many thanks.

Hi.,
For Displaying PDF use interactive form UI and bind data source to context attribute. Now set the downloaded data from RFC to the context attribute. It will display the PDF.,
let the experts reply for ur query..
Thanks & Regards

Calling transaction through webdynpro abap applicatoin

hi,
Is it possible to call an EWT transaction or an transaction from a webdynpro abap application.
Regards,
Divya

The example demo listed works under special circumstance ONLY.
Logon to SAP.
At main menu add a favourite of type WDA.
Choose application wdr_sapgui_demo1 .
Now run demo.
The WDA app appears inside an SAP GUI screen.
Now the when the runtime API call the sapgui manager, a handle to the GUI is available.
The new transaction can now be fired. EG navigate away to new transation.
If the GUI is not already active you have another issue.
I suggest you search the forum for the use of SAPGUI shortcuts and other
such tricks . There has been a few topics and solutions discussed.
Cheers
Phil.

Displaying Smartforms in Webdynpro ABAP

Hi All,
I have to display smartforms in WDA. For that I'm using following link.
[http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0de1eb8-0b98-2910-7996-8a3c2fcf6785?quicklink=index&overridelayout=true]
Now, in my case --
Form Name - 'ZFORM'
Importing Field - 'VBELN'
But, my problem is I'm unable to understand some of the fields, used in Tutorial in the link above, which are --
element_zinput
pernr = stru_input1-zpernr
reinr = stru_input1-zreinr
pdvrs = stru_input1-zpdvrs
I can understand that these must be user-defined. But, it has not defined in tutorial and hence, I'm confused.
Can anyone tell me what are these fields and from where are these coming?
Thakns.

Display Word Document in ABAP WebDynpro

Hi All,
We have a number of word documents stored in the Business Document Navigator (Transaction OAOR) that we would like to display within a simple ABAP WebDynpro. Demo program SAPRDEMO_FORM_INTERFACE shows how to retrieve a document from BDS via class cl_bds_document_set. However, I am not seeing a similiar program for ABAP Web Dynpro.
I was hoping that WebDynpro test application IOS_TEST_SIMPLE_MS would do the trick; however that appears to only work for a MIME repository object. Is there a way to display these documents through ABAP WebDynpro? Can anyone point me to a sample program? Thanks.
John

Hi John
Have a look at this thread [ Approach content repository other way then URL approach |Re: Approach content repository other way then URL approach;.
Thomas Jung delivers some (as always) excellent answers to a very similar problem. If the document is in DMS or BDS really doesn't matter so if I were you I would follow the "cached response" path.
Also, do a google-search for -- abap "cached response" -- and you will find some additional links here (Thomas has even more to offer...).
If you do follow this path please share some details as a follow up in this thread for the benefit of the community at large.

How can we display photo of particular person on webdynpro abap view

hello gurus,
i am very new to webdynpro abap.i have one requirement.could any one can suggest me to overcome my requirement.
in my requirement i have one view.in that view i need to display one photo image which ever saved on my desktoop.if i click on save button i should generate one doc number and update what ever the photo image i have displayed in the view against this doc number.after some time if give the doc number in to docnumber field and click on display button it should display what ever the photo we have saved previously against this doc number.this is my exact requirement.i think for this we need to maintain one Z table to stroe the photo and respective doc.number.for this how can we stroe photo against doc number in ztables.what is the type i supposed to give for photo image field.
could you please any one suggest me on this and could any one send me the sample code if possible.
regards,
babu.

Hello Babu,
I doubt whether you can directly display the image from your desktop into the webdynpro application using Image UI Element. Only solution what I can think of is to load the image into the MIME folder and then bind the path of image in the Source property of the image UI element. But if you ask me this is not a good solution. Let me propose my solution. If no one get back to issue with better approach then you can follow the same
1. whenever the image the is uploaded from the desktop, create this image in the MIME folder ( you search in SDN for creating objects in MIME folder )
2. then bind the path of the image in Mime folder to the Source property of the Image UI Element
3. Once the image is persisted in the DDIC table, delete the image from the MIME folder.
4. to persist the image in DDIC table, create an attribute of type RAWSTRING.
5. Whenever you want to display image from DDIC table into the UI, then again create the image in MIME folder and delete the image from MIME folder when you are existing from the application.
Alternative would be to use the Mime repository for storing the image and in the DDIC table just maintain the Mime folder path for the document number.
Hope this helps you.

Standard program to display which tables are used by Webdynpro ABAP program

Hi Gurus,
I am working on a couple of enhancements in SAP Promotion Management for Retail (SAP PMR) which works on the principle of Floor Plan Management.
I was wondering if anyone would know of a standard program to display the tables used by Webdynpro ABAP?
(or)
Where can I get info of SAP Tables associated to SAP PMR?

Hi,
I am not aware of any standard reports that displays the tables.
If I have to view the tables, I would go to se80, give the package and view all the tables in the package.

Display RSS flows in WebDynpro ABAP

Hi,
I was surprised that my search in this topic on "RSS" did not return any result.
I need for a customer to develop a couple of WebDynpro ABAP screens (without any portal) and to display information coming from a RSS flow inside these WD4A screens.
Any idea how to achieve this, standard solution preferred or via custom coding?
Thanks
Yann

Your question isn't really Web Dynpro ABAP centric. The process to consume and parse the RSS is indepent of the use of classic dynpro, BSP, or Web Dynpro ABAP as the UI. You are probably just going to use the CL_HTTP_CLIENT class to make the HTTP call from ABAP and then parse the RSS with XML or an XSLT. Brian McKellar wrote a nice blog on this some time ago.
/people/brian.mckellar/blog/2004/06/25/bsp-programming-rss-httpclient-xml-xslt
He does his output in BSP, but that part can easily be adapted to Web Dynpro.

WebDynpro ABAP iview display problems

Hi everybody,
I am new to Portal and need some help with the display of a webdynpro iview in the portal. We use portal 7.0 and wish to insert a new webdynpro iview for ABAP in the portal. The webdynpro application displays well the first time, clicking on all options within the applications returns everything as intended and everything looks great. However the second time when we click on a particular option in the application, some icons do not get displayed.
It is as if the second time the iview gets the contents from cache or something. We switched off all cache options within the iview, but it doesn't seem to have any effect.
Has anyone had any experience with this? Does anyone know the solution?
Thank you.
Vedad
