New to Webdynpro for ABAP

Hi Experts,
I am working in Webdynpro Java and Portal Administration for the past three years.
I am very much interested in learning Webdynpro ABAP.
Please let me know what are the skills (in ABAP language especially) i need to know for working in
Webdynpro ABAP. What are the scopes in the coming days for Webdynpro ABAP.
Thanks a lot.

Dear Srini,
Welcome to Web Dynpro for ABAP forum!!!
Webdynpro ABAP is mainly for developing webapplications in ABAP.
WDA includes all the three things i.e. Programming, UI design & Settings (configuration).
As you said you have good experience of 3 yrs in Java. Try to gain some knowledge of ABAP Objects (OOP). It will be helpful to you.
There are lots of threads are available.
Plz chk the below links:

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

Hi Experts,

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

how can I achieve this? Is there any such feature in ALV component?
Any code sample will be really helpfull.
Please help!
Thanks

Display HTML code in WebDynpro for ABAP

Hi, I would like to display a html page in a WebDynpro View, ie: I have the html code in a "string" variable and would now display this string now not with the html tags visible, but as a "real" html page.
I found a thread in WebDynpro for ABAP but I am a little bit lost in converting the logic to ABAP world.
Thanks

>I found a thread in WebDynpro for ABAP but I am a little bit lost in converting the logic to ABAP world.
I'm a little bit confused by this statement. Do you mean you found a thread in Web Dynpro Java, perhaps?
Regardless the approach is possible using the iFrame UI. The warning about the iFrame is that it is deprecated in NetWeaver 7.0 and 7.01 and my not be usable depending upon your support package level. However in NetWeaver 7.02 the iFrame returns to fully supported status.
If you have the HTML content in a string, you can simply place it into the ICM cache. This will provide a temporary URL for the content (you supply the lifetime of the URL) that can be referenced via the iFrame URL or even the LinkToURL if you want to open in a new window.
Here is the code for placing the string into the ICM Cache:
****Create the cached response object that we will insert our content into
data: cached_response type ref to if_http_response.
create object cached_response
    type
      cl_http_response
    exporting
      add_c_msg        = 1.
try. " ignore, if compression can not be switched on
      call method cached_response->set_compression
        exporting
          options = cached_response->co_compress_based_on_mime_type
        exceptions
          others = 1.
    catch cx_root.
endtry.
****set the data and the headers
data: l_app_type type string.
      cached_response->set_cdata( lv_html_text ).
      l_app_type = 'text/html'.
cached_response->set_header_field( name = if_http_header_fields=>content_type
                                     value = l_app_type ).
cached_response->set_status( code = 200 reason = 'OK' ).
cached_response->server_cache_expire_rel( expires_rel = 60 ).
data: guid type guid_32.
call function 'GUID_CREATE'
    importing
      ev_guid_32 = guid.
concatenate '/sap/public' '/' guid '.' 'html' into lv_iframe_url.
****Cache the URL
cl_http_server=>server_cache_upload( url      = lv_iframe_url
                                       response = cached_response ).
wd_context->get_element( )->set_attribute(

In webdynpro for ABAP alv table issue

hello gurus,
                  i am new for webdynpro for ABAP.i strucked at one point at designing time.anybody could you suggest me on this.
thanks in advance.
let me explain my scenario first.
in my webdynpro for ABAP developement i have one alv table having ten fields.i am featching the data for eight fields from one Ztabale and updating , for rest of two fields we need to fill after displaying output using the respective F4 help. Right now these two fields are in input editable mode.now i am getting the values successfully from F4 help and at the same time it is allowing MANUAL ENTRIES also but as per my requirement it should not allow any manual entries . for this i have made these two fields are in readonly mode as like as rest of fields to avoid the MANUAL ENTRIES but at this time i didnot get any F4 helpfor those two fields.
so how can i achive my goal in this thing could any one suggest me.
my final conclusion is we need to get only F4 help values into those two fields . it should not allow any manual values at any point of time.
best regards,
babu

Portal Password Reset Application In webdynpro for ABAP

Hello Friends,
I am new to WDA . I want to create a Password Reset application in WDA like this
[http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0c09b9d-52e0-2d10-3981-86bfa8e19dc3?quicklink=index&overridelayout=true]
Can someone pls give the solution , how to start??
Thanks in advance
Himani

I am afraid that this is not going to be possible for you. From WebDynpro for ABAP, you do not have portal API's to do that.
May be an idea ,If you have SSO in place you could try to call some FM's in r3 side to change the password in r3 system and this would synchronize the UME in portal.

Webdynpro for ABAP - interactive Adobe form - drop down lists not working

Hi all,
I'm trying to create an interactive form for a client using webdynpro for ABAP and I've viewed the demo "Create SAP Interactive Forms by Adobe with Web Dynpro for ABAP" by Thomas Jung, but when I implement it the form following similar steps the form is not interactive.
In the properties of the "InterativeForm", I've tried clicking the "enabled" flag both on and off. I've also tried setting the "displayType" property to both "ActiveX" and "Native". But none of this worked.
I though my problem might be with Adobe reader so I switched from 8.0 back to 7.0 but this didn't make any difference either.
The system we are using is NW04s WAS 700. Any hints would be greatly appreciated!
Thanks,
-tom

Thanks for the suggestion Dezso. I've downloaded a newer version of ACF as indicated by the OSS note and installed it. I'm still having the same issue.
My basic question is what options should I be using in the form and on the InteractiveForm component? It looks like because of the evolution of the product there are multiple options available. I recall reading somewhere that as of a certain SP level we should have ZCI (zero client install) available. The would be our preference. It will be a support nightmare if each user needed a manual download of ACF.exe installed.
Should I click the "enabled" flag on the InteractiveForm object? When I create the form should I use the "Native" drop down list or the one from the "Active X" tab? I would like to use the "List Box" control on the form as well but it is only available in the "Standard" tab. So does that mean I can't get the selections from a "List Box"?
Thanks,-tom

Webdynpro for ABAP and Workflow

Hi All,
I have few applications developed in WebDynpro for ABAP. Now I have the following requirement in one of my application. I am creating some new entries in the custom table based on the user inputs and actions. Before creating a new entry some one needs to approve that. Once the approval is done I have to create a new entry.
I came to know that this can be achieved using workflow. I have no much idea on workflow. Could someone suggest me how I can achieve that please?
Thank You,
Suresh.

Hello,
Use transaction : SWFVISU and maintain the task and the corresponding webdynpro application (parameters if any).
Register UWL with workitem handler and configure UWL.For details,

How can we benefit from WebDynpro for ABAP over Normal ABAP

Dear Guru's,
Please guide me what are +Ves of WebDynpro over Normal ABAP. Once all Applications are developed how can we organize them. For Example In SD module there is sequence of Tcodes to be executed this is true for all modules . Is there any concept involved in this new technology.
For What purpose we can suggest someone to implement in an Organization.
Many Thanks in Advance.
Regards
Ram

Hi Ram,
Here Are some comparisions I made w.r.t Webdynpro for ABAP (also some benifits over Java):
1     "Pros:it will be easier to move your development project through the system landscape if both the UI and business logic are in the same development environment.(Update: This is is less of a concern now that CTS+ lets you bundle your WD Java UI developement with ABAP development objects into a single transport, with SPS13. )
2     tons of custom ABAP business logic is easier to access via WD for ABAP
3     WD for ABAP has a code wizard, so easy to build
4     SAP List Viewer and ALV handled better
5      The biggest thing is the NWDI. Most of the SAP customer have ABAP stack, but not everyone has the Java stack. To develop WD Java you need to set up the NWDI envrionment, like SLD, CMS, CBS, DTR, etc. which is a huge effort if you don't have them in place. While for WD ABAP, the environemnt is normally there as given for most of customers if they have the right version.
6     If your business is in SAP system, I would prefer WD ABAP. There are many WD components available in WD ABAP like select-option, Alv table, F4-help which are not available in WD Java. Beside in WD ABAP you can deal the context node in form of internal table which is much more performant than dealing with the contextelement which is the case for WD Java.

Monitor usage of Webdynpro for Abap Application

Dear all,
How does one monitor how many times a Webdynpro for Abap application is called by users? We have an i-view in the portal that calls a WD4A program in the back-end system. Is there anything in the portal or back-end that will give us the usage information?
Thanks, Neeta

Hi Thomas,
We are not necessarily looking for performance data but how many times a bsp and/or function module is called. The idea is to try and determine how many calls are made to SWN_WIEXECUTE BSP via a URL (http://<hostname>:xxxx/bc/bsp/sap/SWN_WIEXECUTE/MAIN.DO to track a usage of a new workflow approval/rejection process.
We also want track how many calls are made to SAP_WAPI_WORKITEM_COMPLETE function module to track approval/rejection of a workflow process via Portal UWL.
