As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.

Are there any standard web dynpro ABAP or JAVA for material creation(mm41)?

Hi SDN,
I have got the requirement to provide Web Dynpro application for material creation (transaction code is MM41) and I would prefer to enhance standard Web Dynpro more than develop from scratch. Now I got only the Web dynpro ABAP component for create sales order called "LO_OIF_MAIN_COMP" and GUI HTML for purchasing order that come with business package Eh4.
Anyone who know please kindly help me.

>but I afraid that I'm not able to find out what is its component name from application
You could just lookup the WD Application in SE80 and then it will show you the component name. From SE80 choose Edit Object from the toolbar. Go to the Web Objects tab in the dialog. Type in the WD Application name and hit enter. You will then see the details of that application.

Sequencing Problem in Web Dynpro ABAP

Hi Web Dynpro (ABAP) Guru's,
Can anyone tell me how to read a parameter from the WDA url in my view? The situation is like this: My WDA is being rendered in the Portal EP 6.0 as an iView. When my WDA is called the portal also appends in the URL the plant number. I want to grab that plant number and use it in my view to show some default data.
As per other weblogs/forum posts I defined a parameter "PLANT_NO" in the "Default" startup plug of my Main window. I'm using the Get_Data method to read this parameter in the plug. I'm able to read the URL parameter here and so far it is good. Read below for the problem..
If I understand the order of operations correctly, doesn't the views get created, then the default plug code is run, then the views are placed on the window and then shown to the user. Since my views are created before my default plug is run I DO NOT get the URL parameter value in the WDDOINIT of my view. When I debug the application, the WDDOINIT of the embedded view gets called before the Default startup plug. Am I missing something here?
If someone can tell how to read the URL parameter in the WDDOINIT (instead of Default Startup) of the view I could default in the data I want to display. OR any other suggestions to get past this problem would be appreciated.
Does this make any sense and does anybody have an idea of where I could find some info about how to do this?
Thanks much for your help. Points will be awarded.

Thanks Klaus for the response.
I don't want to read the parameter from the default plug, but need to access the URL parameter and display default data in my view. Let me explain the scenario:
My Web dynpro application is called from the Portal. The Plant number is passed in the URL as:
http://...../sap/bc/../../<Web Dynpro Application name>?PLANT_NO=0012
I want to show Material Stock values in the view for Plant "0012". To access this value I've defined a parameter with same name (PLANT_NO) in the default startup plug of my main window. I get access to the URL parameter through this plug parameter.
I have only ONE view embedded in this window where the Stock values are selected from table MARD for the specified plant. I want to get the plant value from URL in my WDDOINIT method to make this selection from database. I'm then binding the results to the view table UI element. My problem is that the URL parameter is read in the Default plug, but the data selection and view binding happens before in the WDDOINIT method where I don't know the plant.
Again, I don't want to read the plug parameter, but I want to get the URL parameter (PLANT_NO) and then render the view based on the data selected for this parameter. Please let me know how this can be achieved by reading the URL parameter in WDDOINIT method (Constructor) so that it can be used subsequently in the application.
Thanks for your help and looking for a resolution.....

Is there a way to get Web Dynpro ABAP available in a ECC 5 - NW2004 env?

We will start developing an offline Adobe interactive form with email functionality for ECC 5 on very short terms. We have to decide asap what client/server configuration we will use for this new functionality. We will also develop an online interactive form and an offline form with upload/download functionality for ECC 5. We will have to setup a client/server configuration that supports all 3 scenario's.
The main reason we would like to have NW2004S available for ECC 5 is because we would like to develop the forms in Web Dynpro ABAP instead of Java. Guided Procedures is a "nice to have" too, but not really important at this moment.
At this moment we think we have 3 options:
1. Investigate if we can make an Adobe solution in WDA for ECC 5 with our current setup
2. Upgrade ECC 5 - NW 2004 -> NW 2004S to get WDA functionality available
3. Install ADS for NW 2004 to be able to create Adobe solutions in ECC 5, then we will have to develop in WDJ
1. We have the following configuration up and running: NW2004S - CRM 5 and ADS installed: both Java and ABAP stack work properly. We are wondering if we could develop an Adobe interactive form in Web Dynpro ABAP in CRM 5 using BAPI's to retrieve the data from ECC 5 and put it on the form for display or update purposes. Also we have questions about the email functionality: do forms have to be send by email via a mailserver from ECC 5 via CRM 5 and back or can this be done directly from and to ECC 5 or is it not possible at all? Also we don't know if we can develop an online interactive form for ECC 5 via CRM 5. The current setup is not a real option for us right now as we see far too many uncertainties. Does somebody can give us some answers on the possibilities we are looking for?
2. My assumption is that upgrading ECC5 to ECC6 can be compared with upgrading 46C to ECC5. If my assumption is correct, this would mean an upgrade project with a 6 months leadtime within our company. If my assumption is wrong, please let me know. This upgrade will happen some day, but it has not been planned for 2007. So unfortunately, for us this is not an option at the moment because we cannot wait that long. I was hoping an upgrade of NW2004 -> NW2004s was not that time consuming but I guess this can be compared with a SAP upgrade project like 46C -> ECC 5.
3. Installing Adobe Document Services for NW2004 is not our preferred solution but we think it is the safest/easiest solution at this moment to get started with Adobe interactive forms for ECC 5 on short terms. We will have to develop in Web Dynpro for Java, so be it.
WDA is not a must but if we can find a client/server setup which gives us the possibility to build in WDA for ECC 5 functionality, that would be great. That's why I dropped the question on SDN. I want to be sure we choose the best option possible at this moment for us.
kind regards
Angelique

Yesterday I got new information through SDN which sounds very interesting:
There are technical repository integration points between ECC and the underlying SAP NetWeaver release. To get Web Dynpro for ABAP, you could install a stand-alone SAP NetWeaver 2004s system (without ERP) side-by-side.
Somebody else wrote: we set up a 3-system landscape of NW04s and have configured single sign on and trusted RFC's so that users can hit the webdynpro pages via the portal, and those systems make the necessary queries to the backend systems via RFC.
Does somebody know if this stand-alone system could be a proper solution for our situation? Does somebody foresee any problems related to Adobe LiveCycleDesigner or ADS?

Shooping cart creation in SRM 7.0 using web dynpro ABAP classes.

Hi,
We have recently upgraded to SRM 7.0 from SRM 4.0. We are using customized portal application for the creation of the shopping cart.I am planning to create custom FM which will use the standard Web dynpro ABAP classes to create the shopping cart.
Could you please guide with the classes that are need to be implemented and the sequence of the classes used in the shopping cart creation.
I think these are the classes that are used in the standard web dynpro ABAP component.
CL_FPM_EVENT ->                  Creates an instance of this class based on an event ID.
CL_BADI_FLT_DATA_TRANS_AND_DB -> Data Handling: Transport and Database.
CL_EXITHANDLER ->               Class for Ext. Services Within Framework of Exit Technique.
CL_EX_BBP_DOC_CHANGE_BADI ->     BAdI Class CL_EX_BBP_DOC_CHANGE_BADI.
CL_BBP_OBJECTS_ACCESS ->         Access Functions for Object Types.
/SAPSRM/CL_PDO_BO_SC ->          Shopping Cart BO.
Your expert comments will be appreciated...

SRM 7.0 Web Dynpro ABAP Customization

Hi ,
Upgrading from SRM 5.0 to SRM 7.0 and would require customization at the Web Dynpro ABAP Component for RFx.
I need to put a pop-up screen when the Buyer clicks on the "AWARD" button on the Bid Screen. Now I am not able to find the award action/event at the Web Dynpro component level where I have to put the pop-up code and other related logic. I also tried getting into the SPRO and find the class which may contain the AWARD event. Please let me know the solution to this problem. Thank you.
Manoj

Hi Akash,
Thanks for the reply. Can you please guide me through how to go about the enhancement, keeping the original functionality of the Award Button intact. And I understand coding in method of interface is not possible.

Integrating Flex/Flash in Web Dynpro ABAP(Netweaver 7.0) need info!

Hi all,
I need to embed a flash or a flex object inside a web dynpro abap application.I am working in Netweaver 7.0 and i don't have enhancement pack 1 installed.Is it possible ? If it is possible can anyone please provide me the coding and configuration details.
Thanks,
Saikat

I'm afraid that the SAP supplied integration technology - call FlashIslands - is only available from NetWeaver 7.01 and forward. You could perhaps do some simple integration (very little data transfer) with the iFrame UI element - although the iFrame is deprecated in 7.0 and 7.01, but does return to full support in 7.02. The other option would be to use the NetWeaver Portal or NetWeaver Business Client and have two iViews within the page. One iView would have WDA and the other some external technology (BSP, JSP, etc) to host the Flash/Flex content. Not tight integration, but you could potentially use Portal Eventing to at least communicate events.

How to configure SSO for web dynpro ABAP (not web dynpro Java)

Hi Experts,
    I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
     procedure"
   Then deleted all logon procedure other than "SSO Authentication" and saved.
3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
     signal).
4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
After all this settings I opened a browser enter above URL and hit enter but there is an error
There is no login page. It directly showed this error page. No cookies is saving.
Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
How to set the for single sign-on?
Thanks in Advance

Web Dynpro ABAP in SAP E-Recruiting

Hi,
We just imported SP8 for our SAP E-Recruiting 6.0. SP8 offers Web Dynpro ABAP as candidate UI. One question we have is how WD pages incorporated for recruiters who still use BSP pages. For example, when a recruiter logs into E-Recruiting and finds a specific candidate, he/she can click on "Candidate Profile" to get to that candidate's pages. In BSP technology, recruiter actually uses exactly the same pages that candidate uses for Work Experience, Education, etc.. With candidate UI using WD technology, does recruiter use the same WD pages when displaying candidate profile information? I have been searching all the possible places, such as IMG, SICF, in order find a spot so that I can set the switch on, but so far unsuccessful.
Any help is greatly appreciated.

How can I call a java object from Web dynpro ABAP application?

I made Web dynpro ABAP application and posted it to SAP EP.
For certain business purpose, we need to call external 3rd party java object using 3rd party's java api in Web dynpro application.
Is there anybody who experienced this kind of java interface issue?
I know Web dynpro Java environment can fully support this kind of requirement. but regarding Web dynpro ABAP, I couldn't find any clue for this.
Any comment or suggestion would be greatly appreciated.
Thanks,
Raymond, ABAP Consultant

if you have jco configured, then you can make calls to java api from ABAP .

How to fix few rows in ALV after filtering on a column in Web Dynpro ABAP

Hi,
I have the following requirement:
In an ALV, when i filter based on a column, then this filter should not be applied to 2 of its rows.
These rows relate to totals. The totals are manually calculated as they require other component information too.
Along with the filter result, these total rows have to be displayed.
Let me know in case ALV in Web Dynpro ABAP supports this functionality.
Regards,
Rekha

Hi,
ALV table does not support this functionality.
You can display the total in an another table instead.
I had the same requirement with total and had to display the totals separately.
Thanks,
Feroz

Web Dynpro ABAP Stylesheet - Portal Integration

We have a Web Dynpro ABAP being displayed through a Portal iView. The Portal server and the Web Dynpro ABAP server are separate. Our problem is in getting the Web Dynpro ABAP to use the stylesheet of the Portal.
We can make this work by forcing an external stylesheet (via application parameters, global Dynpro settings, or passed on the end of the URL), but we have to hard-code the full URI of the Portal stylesheet. This would be very hard to manage if we hard-code every iView's CSS location (or set every individual Web Dynpro's application parameters), and we want instead for the Portal to supply whatever the user's stylesheet is dynamically.
So what we want is: if we change the Portal stylesheet, the Portal would just pass the new stylesheet URI to our ABAP Web Dynpro iViews without manual modification of the iViews.
Here is an example of what works:
http://our-abap-server.com/sap/bc/webdynpro/sap/cprojects?sap-ep-themeroot=https://our-portal-server.com/irj/portalapps/com.sap.portal.design.portaldesigndata/themes/portal/ourportalstylesheetname
Shouldn't the Portal iView automatically pass sap-cssurl or sap-ep-themeroot to Web Dynpro ABAP? We have "Supply Portal Stylesheet" checked on the iView it just doesn't pass anything to the Web Dynpro ABAP. Why wouldn't SAP pass this parameter dynamically to the Web Dynpro ABAPs? Is this a product error?
There seems to be a great deal of confusion about this on the SDN message forums... I think this may be the core issue.
We are using a 7.0 SP13 Portal with an ECC 6.0 SP12 backend.

Now that you mention it, I ran into that exact same issue -- the application parameters didn't work for hard-coding the theme. The fix ended up being the web server semicolon thing I mentioned earlier (that was why the parameter didn't make it to the backend).
The themeroot is automatically sent to the backend from the portal, so you shouldn't really have to manually send it as a parameter anyways.
I'd suggest talking to your network guys. Also this could be the result of the SP you are on (we're on 13 for the portal and the backend system -- maybe this feature doesn't work in some earlier SP's?). There are also some options to force the theme as a WD application parameter on the backend side, which you could check into. Details on those are here:
[http://help.sap.com/saphelp_nw2004s/helpdata/en/7b/fb57412df8091de10000000a155106/frameset.htm]
Also you could look at the requests being made by installing HttpAnalyzer in your browser. You can inspect "post" parameters going from the portal to the backend system. One of those posts (the first one to the backend system) should contain the parameter sap-cssurl (same kind of thing as sp-ep-themeroot). This is where our problem turned up as this parameter was not being posted.
Lastly, make sure that your frontend portal and backend portal are in the same domain. For instance:
frontend.domain.com
backend.domain.com
If your backend and frontend are in different domains it messes all kinds of things up, including stylesheets I think. If you can't get around this, then read about domain relaxing (but I highly recommend getting the domains the same).
When we started, ours were:
portal.dx.company.com
sap.company.com
This created all kinds of problems. Putting our systems in the same domain with the same protocol and fixing our little semicolon web server problem fixed basically all of our portal complaints. Up until that time, we had also had many problems with session management (backend sessions were getting stuck until the HTTP timeout).
That's all I know. Good luck.

Upload a .xls file in web dynpro abap

Hello,
I want to upload a .xls file into a internal table in web dynpro abap (Netweaver 7.31).
The file is not delimited, is not an csv file.
In my view I have an fileUpload UI Element with the attribute data is un attribute type XSTRING and the following function module are not in my system:
HR_KR_XSTRING_TO_STRING
ALSM_EXCEL_TO_INTERNAL_TABLE
How can I upload the file with this format?.
Thanks in advance.
Xavi

Unless the files are zipped together into one archive file, you have to do them one at a time. Furthermore with the normal browser based fileUpload UI element, you must do them one at a time and the user must manually select each one (browser security limitation).
If you are on 7.01 you can use ACFUpDown to perform multiple file uploads, but there is no file dialog or directory scan so file selection is difficult.
If you are on 7.02 you can use ACFUpdown and it has a multiple file open/save dialog.
If you are on 7.01 you could use FlashIslands to perform the multiple file upload. I have a tutorial and source code sample for this on SCN.
If you are on 7.01 you could also use ACFExecute to run a batch script on the client side that zips all the files and then upload the zip archive.
