Advantages of BSP over Webdynpro ABAP

Hi,,
Can anyone please explain what are the advantages of BSP over WebDynpro ABAP, In what cases do we need to stick with BSP?
Thanks,

Hi,
There is a SAP web GUI map and it contains different technologies as follows:
If you have the SAP screen already available , then the best solution would be to go for the ITS solution(Web Gui).
But if you were to compare the man days required to code a dynpro and a web dynpro screen from scratch then they would approximately be the same.
Yes if you want to leverage on Web Dynpro you will have to currently code all screen from scratch , and encapsulate your backend logic as function modules.
Apart from BSP you have the option to use Portal Development Kit (if you have SAP EP in your landscape) . JSPHTMLB(tag libraries)JCO running on WAS 6.2 or 6.4 or other Java server.
If you have just one screen and currently dont have the WAS 6.4 in your landscape and it would involve delays interms of procurement , setup and training, then its better you go with either of the above solutions depending on the skillsets in your team.
If you can make an FM of your trx, the BSP solution might be the easiest step. No additionial knowledge (except from some HTML(B)) is needed.
Advantages of web dynpro:
Additionally,
I would say if you would want a quantum leap in advantages by preferring a UI solution , then it has to be webdynpro be it ABAP or Java.
Some of the features that I have heard about and noticed as well is
-> Metadata based which means tomorrow SAP could easily support a new client without you not requiring even to change a line of code.
-> Support for Java gui and Win gui for web dynpro coming up(over http)
-> More professional UI and flicker free
-> Faster development time when compared to BSP or JSP
-> Future proof
Disadvantages:
On the down side
-> You loose control on so many things that you took for granted in web programming such as javascript support, DHTML
Hope this will help you.
Cheers,
Darshna.

Bsp Vs Webdynpro ABAP

Hi All,
I am new to the concepts of BSP and ABAP web dynpro,Can some body please guide me on what is the difference between BSP and ABAP web dynpro.
Thanks in Advance.

Hi Varun,
think of WebDynpro as a replacement UI technology for SAPGUI. It is designed to support interactive transactions (i.e. multi-screen) with a standard look and feel for professional users.
BSP is designed to support simple web-style transactions where the user has a fairly simple interaction with the page and you can tailor the user experience to look any way you like.
So WebDynpro would suit a rewrite of the Sales Order Entry transaction. BSP would suit building a web-style shopping basket experience. and
i. In Web DynPro there is lesser coding when compared with BSP. i.e Web Dynrpo are more dependent on Designing rather than coding whereas, BSP's are done by coding.
ii. There is low possibilty of customization in web dynrpo, i.e We need to use only the available color or style themes available..It is not easy to have user defined color themes but in BSP we can have our own color themes at ease.. and
The difference is a little bit more subtle than that. Both webdynpro and BSP call ABAP function modules from HTTP. The BSP interface does this via programming in SE80, the webdynpro does this via programming in the Java development workbench. The BSP enters the SAP systenm via the ICM and is 'routed' to ICF where call are then made to executre ABAP (a good example is we use SOAP BSP's). Webdynpro routes via the ICM to the Java engine which then executes the Java to cann the functions via an RFC interface called a JCo connection.
Another difference to note is SAP is now dedicated to using webdynpro as its internet platform of the future. This indicates that it aims to eventually retire such things as ITS and BSP.

Pass data from BSP to WebDynpro Abap

Hi,
Can anyone pls tell how to pass the data from BSP to WD4A Application.
I am trying to call the WDA URL using the class CL_GUI_FRONTEND_SERVICES in BSP,but it is giving a run time error.
How to call the WDA URL from the classes in BSP & not using iFrame ?
Thanks,
Krishna

Hi Raja,
Can u pls tell the class which the object navigation->goto_page( url ) refers to.
My main requirement is to call the WDA URL from a class in BSP Application.
Since there is no GUI connection i'll be not able to use class CL_GUI_FRONTEND_SERVICES.
So i need a class which will call URL before passing data.
Thanks for the same,

Vamsi.

Advantages of BSP

Hello All,
Can you pen down the advantages of BSP over ASP and what
are the side effects of using BSP considering the load
on the server where it is running.
Would be glad to have your views......
TQ,
- Sravan

What's the biggest single advantage to using BSP?
That fact that you write your web pages in ABAP of course!
That is assuming that you know and like ABAP as a programming language. All joking aside this is a huge benefit if you have a development team like ours (people with many years of experience programming ABAP in the R/3 environment). The transition to a Web Based development platform is made that much easier by not having to learn the syntax and (more importantly) the ins and outs of a new programming language.
As far as performance and other technical details, the weblogs mentioned above should give you plenty of reading. I can add to those by telling you about the experiment that we did before we choose to use BSP. We built a purchase requisition application in both BSP and ASP.Net. The ASP.Net application used the .Net Connector to access all of its data while the BSP used native RFC naturally.
We ran both applications on indentical hardware and did some tests. Our tests weren't the most scientific in nature, but let's just say that BSP visibly won hands down in the performance department. That's not a dig at ASP by any means. I like it just fine and feel that it is a good tool as well. We just found that in our SAP environment we got much better performance from the BSP tools.

Advantages in Webdynpro Java Over WD ABAP

Hi All
Can you please let me know what are the advantages in webdynpro java over WD ABAP??
if anybody helps quickly then it would be great help to me
Thanks
Trisha Rani

Hi,
Both WDA and WDJ are almost same in designing and programming.
In relation to the business packages SAP already provided allmost all of them in java and in the future all the Business packages also available in ABAP. It's all how you want to develop the application. In sap portal world some applciation which we can develop with ABAP Web Dynpro and some applications with JAVA Web Webdynpro as SAP Web AS available as dual stack.
If someone already has a strong ABAP background and has WD for ABAP available they should probably use that. If they are a J2EE developer they should probably use WD for Java but it is likely they will also then need some ABAP support for the backend systems.
I think more customers may be asking for WD for Java projects simply because it has been around longer and is more widely available to customers where as some cutomers prefer to develop their application using ABAP Web Dynpro because of SAP propritary. But ultimately it's again all our interest and customer.

Webdynpro ABAP called from IView JAVA works over http but doesn't over http

Hello gurus, like I said in the subject, we have integrated inside our JAVA portal a WebDynpro ABAP and it's working good over http protocol (http://<servername>:<http_port>/irj/portal), but when you browse the portal over https protocol (https://<servername>:<https_port>/irj/portal), everything works fine exept the WebDynpro ABAP, is like if the javascript components didn't be loaded completly, because the buttons doesn't make anything, and only half of the table that is supossed to be loaded is showed.
Do you know what kind of configuration I'm missing?
Thanks and best regards

You have to note here that for webdynpro ABAP applications, the http/https request is actually served by the backend server.
So, while accessing your webdynpro ABAP application, the request will be like:
https://<mybackendserver>:<backendport>/bc/sap/.....
While creating a system object in your portal (System landscape), you will need to adjust the protocol to https and also set the appropriate https port of the backend server. Also, HTTPS/SSL communication should be enabled on your backend server.
Please check the definition of your system object.
You can find more information by turning on a HTTP trace and checking how the request is routed to the backend server upon accessing the WD4A application.
Thanks,
Shanti

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.

Calling a webdynpro ABAP component from a BSP...

We have a BSP application. On which we have a tab strip control. Upon clicking on one of the tabstrips, is there a way I can launch and display an output from a webdynpro ABAP component?
Any ideas will be appreciated.
Thanks

Raja,
I tried get the iframe tag
<IFRAME NAME="Frame1" SRC="your_web_dynpro_link.htm" >
</IFRAME>
with the SRC = "<the URL from the web dynpro application>"
Did not work. I am sure I am doing something wrong. In fact it did not work even for a BSP application.
Any ideas anyone?
Thanks

Advantages and Disadvantages of webdynpro JAVA over J2ee?

Hi,
Can anybody provide me the advantages and disadvantages of webdynpro java over the J2EE?
Regards,
Harish.

Hi,
Webdynpro is the SAP standard technology for developing business user intrefaces.
Webdynpro is like the frame work which follows the MVC Design pattern.
Webdynpro uses most of the UI developement as declarative approach , i.e. most of the code will generated by the framework. so it will reduce the developement efforts.
Adaptive RFC model to connect with SAP systems.
All these are advantages over than the J2ee.

Advantages of netweaver(webdynpro abap) comparing to sap(abap

plz tell me the advantages of netweaver(webdynpro abap)comparing sap

Hi,
Broken link removed
Also, I have the official Web Dynpro for ABAP documentation. Please let me know if I should send it to you.
Hope that the following also helps you.
Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web
applications in the ABAP environment. It consists of a runtime environment and a graphical
development environment with special Web Dynpro tools that are integrated in the ABAP
Workbench (SE80).
Web Dynpro offers the following advantages for application developers:
● The use of declarative and graphical tools significantly reduces the implementation
effort
● Web Dynpro supports a structured design process
● Strict separation between layout and business data
● Reuse and better maintainability by using components
● The layout and navigation is easily changed using the Web Dynpro tools
● Stateful applications are supported that is, if the page is changed and the required
data remains intact so that you can access it at any time throughout the entire
application context.
Note that stateless applications are not possible.
● Automatic data transport using data binding
● Automatic input check
● Automatic operation of the Web Dynpro application using the keyboard
● User interface accessibility is supported
● Full integration in the reliable ABAP development environment
Web Dynpro Architecture
Definition
Web Dynpro is the SAP NetWeaver programming model for user interfaces (UIs).
The Web Dynpro model is based on the Model View Controller paradigm, and has the
following features that build on the classic dynpro model:
● Clear separation of business logic and display logic
● Uniform metamodel for all types of user interfaces
● Execution on a number of client platforms.
● Extensive platform independence of interfaces
Structure
Metamodel Concept
Web Dynpro provides support for developing Web representation of a business application.
You use specific tools to describe the properties of a Web Dynpro application in the form of
Web Dynpro metadata. The necessary source code is then generated automatically and
executed at runtime. In addition to the events offered by the framework, you can also define
your own events for a Web Dynpro application. However, the event handling must always be
programmed in separate source code areas which are executed automatically when the event
is triggered at runtime.
In Web Dynpro, each user interface is always made up of the same basic elements. These
elements of the metamodel can be statically declared using Web Dynpro tools.
It is also possible to implement elements of the metamodel at runtime and to change them or
reintegrate them at runtime. Using these implementations, you can make any changes or
enhancements to a user interface that has been created by declarative methods by
generating new interface structures at runtime.
This means that you can combine declarative processes and the implementation of source
code.
Graphical Development Tools
To support this declarative concept, both the SAP NetWeaver Developer Studio and the
ABAP Workbench contain a range of Web Dynpro tools. You can therefore generate a large
proportion of a Web Dynpro application using the tools provided, without having to create your
own source code. This applies to the following parts of the application:
● Data flow between the front end and back end
● Layout of the user interface
● Properties of user interface elements
The Web Dynpro tools enable you to create source text areas manually within generated
source texts. These areas are not changed if the source code is regenerated.
Separation of Business and Application Logic
Using Web Dynpro enables a clear separation of business logic and display logic. A Web
Dynpro application runs on the front end and has local or remote access to the back end
system via a service. This means that the display logic is contained in the Web Dynpro
application, while the business logic and the persistence of the business objects run in the
back end system. The following options are currently available for connecting Web Dynpro
applications and the back-end system:
● An interface generated using adaptive RFC, through which BAPIs of an SAP system
can be called
● An interface for calling Web services
● A self-generated interface
The source code required for connecting the Web Dynpro application can be generated
from a UML definition of the Web Dynpro interface. A UML definition can be imported
into the Web Dynpro tools as an XML file.
Conversion of the Model-View-Controller
Conversion of the Model-View-Controller Programming Model
Every Web Dynpro application is structured according to the Model View Controller
programming model:
● The model forms the interface to the back end system and thus enables the
Web Dynpro application access to data.
● The view is responsible for the representation of the data in the browser.
● The controller lies between the view and the model. The controller formats
the model data to be displayed in the view, processes the user entries made by the
user, and returns them to the model.

Advantages of EP over SAP BI Web Reporting

Dear Experts
Can you please share your inputs on Advantages of EP over SAP BI Web Reporting?
Appreciate if you could share any presentations or documents on this.
Thank you in advance.
Best Regards
PKC

Hi,
They are absolutely different environments. With EP, you can develop WebDynpro Applications, using ABAP or Java, integrate Internet Service, develop applications with Visual Composer, ... It's much more than a reporting environment. You can integrate BI reports on EP, using iviews portal components.
Look these threads:

Javascript server events in webdynpro ABAP

I am migrating an existing BSP application to webdynpro abap. Few of sections, in existing BSP application, uses java script coding to trigger few server events. For example it uses a flash charts on click of which some filtering logic is written on table. Similar logic needs to be placed for webdynpro. I used Iframe to display this charts. Charts are rendered properly but I am not able to raise the actions or trigger events on server as I dont have access to parent.document object of my parent view.
I get access denied/ permission denied error.
Cant we trigger server action or event using JavaScript from child IFrame.
With Regards,
Nitesh Shelar.

Hi Nitesh,
Integrating custom java script is not supported. There are still a few benefits BSP has over WDA. Well, you could put the flash object inside of a BSP application and use portal eventing to communicate with WDA.

Thomas

Generated code WebDynpro ABAP

Hi all,
I am setting up a tool that counts the number of specific lines written for a SAP project, for KPI purpose. It is already working for reports, includes, functions (group and functions), classes, BSP applications and so on....
I am now looking for a way to count the lines of codes written in a Webdynpro ABAP application. Does anyone knows where is the code generated? In what format (classes, reports) ?
Quick and Helpful answers will be highly rewarded.
Yann

Hi Yann,
Code will be generated as class. IF you want the class name of current webdynpro component that is generated, right click on the webdynpro component -> select check -> extended syntax check. New window will be opened in which program name will be specified. Remove the "" ==CP" suffix and remaining part is the class name of the current webdynpro component.
Thanks,
Prashanth

Webdynpro ABAP/Portal. Plugin HTTP connection issue on WaitingEventQueue.js

Hello,
We are experiencing a strange Portal Behavior with our Webdynpros. Our portal contains several iViews including some Webdynpro (ABAP) and some reporting transaction calls that use SAPgui for HTML.
When portal is called for the first time and a user logs in, two connections of type RFC can be seen for that user in SM04 in our ERP system. All iViews work as expected. For example, calling the Time Management webdynpro closes one of the RFC connections and starts a new Pluguin HTTP connection. We can go back and forth between the welcome page and this Webdynpro with no issues.
If we then select one of the reporting transaction codes, the portal launches the SAPGUI for HTML. Report retrieves and shows data, and then we close using the "Exit" button provided by the sapgui for HTML
Next we try again to launch any webdynpro (abap), but SM04 shows that the new Plugin HTTP session gets stuck and spinning mid way, and will stay there. Refreshing the Portal screen with F8, navigating back and forth, logging off and on again has no effect. The webdynpros will not launch again. Only webdynpros are affected, any of the reporting transactions can be called successfully over and over.
We have figured that deleting Temporary Internet files (we are using IE 7), and in particular by just deleting the WaitingEventQueue.js?XXXXXXXXXXX file, the system will break away from the spin loop and show the webdynpro again, but eventually it will get stuck again, and asking the users to delete their Temporary Internet Files every 5 minutes is not a workable solution
I have reviewed the contents of this javascript file at different points during the test, and the contents do not change, so deleting the file and the recreate process must be resetting somehow the queue and allowing for a new correct communication.
Is there a way to properly reset this event queue (for example from ABAP, when the webdynpros are reloaded) in order to avoid the spin loop?
Thanks for any help!
Andres

Well, we got the issue resolved, so here is what we did, in case anybody is interested:
Tested again our portal with multiple versions of Internet Explorer, in particular IE8 and IE6, the Webdynpro behavior was normal (no timeouts or locks). It even worked when we installed IE7 in a brand new machine and tried our portal.
So we started suspecting if maybe the particular IE7 that we install internally (with specific settings and policies) may be the culprit. We took a desktop that was producing the timeouts and used the following options in IE7:
Tools->Internet Options->Advanced(tab)-Reset Internet Explorer settings
and, voila! the next time we ran there, the portal did not create any timeouts.
We even asked our desktop support team to uninstall and reinstall IE7 in the same machine after we did the reset, and even after the re-install that the timeout problems did not re-appear.
One of the things that the "reset" option does is delete the Add-ons used by IE.
So as a last test, we took a machine that was presenting the problem and went to the Internet Options to disable all the add-ons (in the Programs Tab). The error disappeared.
And even after enabling back all the add-ons, the error would not return.
Conclusion:
Without being able to pinpoint the specific add-on (or combination) that causes the problem, we suspect that some of them conflicted, causing IE7 to behave abnormally. Disabling them all, restarting Internet Explorer, and enabling them again, makes the WaitingEventQueue.js work as it should
