BSP and ABAP webdynpro

Hi wizards,
I am planning to start working on POC (Proof of concept). This requires BSP to be integrated with ABAP webdynpro. Can some throw some light on how this integration can be done. ie sharing the context values between both applications.
regards
Vivek Nidhi.

Well BSP and Web Dynpro ABAP are very different when it comes to internal architecture. Just because they both run in a browser doesn't mean they can be integrated like you describe. You could run both a BSP and Web Dynpro ABAP application in separate frames within the browser; however to the backend server these would be two completely separate processes running in their own memory space.
First of all you couldn't directly share the context values. BSP doesn't even have the concept of a context. You could pass some keys via URL parameters or Server Cookies. You might even be able to pass larger amounts of data. However the eventing becomes a bit of problem. The exception here is if you use the NetWeaver Portal. Then you can use Portal Eventing to pass data and events between the two applications.

BSP and ABAP Search Tools

Working through the Recruitment Package that is a BSP application with abap classes I have stumbled on several situations where I need the ability to grep(search) the files in the application. The where used appears to be buggy and sometimes it will resolve and sometimes it comes up blank. Has anyone found any ways or tools to search the entire application code for keywords or a way to download all the abap classes and bsp pages to the file system to run grep on them?
Thanks in advance if someone has a solution this would increase my productivity quite a bit.
Thanks,
Stephen

ESS and CATS available in ABAP webdynpro

Hi Friends,
Currently we are under ECC6.0 with the following SP13.
SAP_BASIS 700 0013 SAPKB70013 SAP Basis Component
SAP_ABA 700 0013 SAPKA70013 Cross-Application Component
And iam looking is the ESS and CATS are available in ABAP webdynpro , i know thta these are available on JAVA side.
If i want to get ESS and CATS in ABAP Web dynpro , what we have to do ???
Could you send me useful links for ESS and CATS in ABAP webdynpro on Portals side.
Srinivas.

Thanks To your Reply.
So we have to live with current ESS which is in Java Iviews on portal side.
There is no as such ESS availble with SAP SP17 or EP7 side for ABAP web dynpro.
If we want to make it available , then we have to go for custom development right.
But Travel & Expenses are available in both JAVA webdynpro and ABAP webdynpro , how come SAP give partly give the package in JAVA and ABAP.
Please clarify me.
Srinivas.

My scenario : I have to create a work request in a ztable that I have created.
For this 1) create a uniques number using number_get_next
2) insert the values into the z table and show message
what is happening -->
Application appears with no problems.
when I click on button message appears
What is not happening on the portal
number get next doesnot get created

Diff between BSP and WEBDYNPRO FOR ABAP?

Hi All,
can anyone let me know the Difference between BSP's and WEBDYNPRO FOR ABAP.
Regards,
Ravi

Hi Ravi,
In truth, Web Dynpro contains many of the enhancements than BSPs....like built-in value-help and select options...... they
will become standard in Web Dynpro. But these can also be added to BSPs also.
There are several architectural differences between BSP and WDA. WDA has some advanced features but more restrictive framework compared to BSP.
WDA is stateful only. While BSP supports both stateful and stateless programming models.
WDA doesn't aloow us to use our own custom HTML, JavaScript or other controls. To provide compatibility the rendering logic is completely hidden from the developer.
On the other hand, BSP has no such restrictions and allows an extreme level of custom rendering. This makes BSP a perfect platform for applications that require pixel-perfect layout or specialized UI elements.

How to call a BSP Application inside Webdynpro for ABAP

Is there any way to call a BSP application inside the webdynpro ABAP application..
The Input screen will be the BSP page and when the user click the action it have to trigger some data in BSP and in turn it have to collaborate the manipulated data in webdynpro and shows the output in webdynpro or in BSP..

pls refer to http://help.sap.com/saphelp_nw70/helpdata/EN/30/1b62799d786445a72ad85acb4fd55b/content.htm

Your opinion on: BSP or Java Webdynpro or ABAP Webdynpro?

Could you please give me your opinion on the business scenario we have here:
We are implementing SRM 4.0 with backend R/3 4.6C, WAS 6.4 and Portal 6.0. SRM has its typical shopping cart applications mainly for procurement and the workflow trail displaying the approval. The client wants us to build a few custom forms on the web frontend of SRM (or may be in Portal). The idea is to store these forms and display when needed with the status info just like a shopping cart.
<b>Now the requirements for these forms are as follows:</b>
1. These forms will have multiple fields which need to have the F4 kind of help. (the F4 options will reside in SRM or R/3)
2. The form should have some kind of a ALV grid (autoexpanding feature) which will allow the user to put in multiple line items so that they could submit more items on one form.
3. Users need to be able to attach a spreadsheet to the form which should not be editable once the form is submitted. The attached spreadsheet should be stored. (We are planning on using Archivelink Filenet for this)
4. Upon submission, a workflow will be kicked off as per the defined Org structure for approval of the form.
5. After submission, the user should be able to go and view the approval status of the form and also print the summary of the values that he entered in the form. (may be a smartform could be provided for this)
We looked at different options to accomplish this task:
<b>BSP:</b>
Creating BSP pages and giving access as links to the user on the webfrontend of SRM. Now, if we go the BSP route, we need to develop in SRM as the R/3 4.6 c does not have BSP development capabilities. If we take this approach, I am not sure if all the above requirements (specially like attaching spreadhseets) will be met with BSP pages.
SAP Webdynpro Java:
It seems that the Webdynpro is easier to use because of the graphical tools available. But the only problem if we go this route is that we will have to find a java guy.
SAP Webdynpro ABAP:
We currently have WAS 6.4. As per the documentation, the ABAP Webdynpro development tool is available from NW04s onwards. So, we are still not sure if we could use it. But, we want to push towards upgrading if necessary. Being an old time ABAPer, developing ABAP Webdynpro seems do-able. (i know it may not be that easy).
Last but not the least, DIALOG Program:
Creating a dialog program in R/3 or SRM seems fairly simple. Then, an iview could be created on the portal for this transaction, though at this point I am not sure how a spreadsheet could be attached and stored within a dialog program.
The creation of the workflow may not be that bad after the original form is designed. The graphical display of the approval trail might be difficult, but we might get away with a report for that. For printing the details of the form, I guess I could develop a smartform and put out a button on the screen to print it out in the display view.
Could you please give me your opinion / best approach for accomplishing this task, keeping in mind the complexities of these new dimension products?
Thanks
Sri

I would say that all four solutions to solving your tasks are technically feasible. Here are some thoughts that I had however:
First ABAP Webdynpro: it is true that ABAP webdynpro is only available with Netweaver04s. 04S is still in ramp-up which means that only a subset of the customer base is allow to implement it. It will not become generally available until later this year (check the service marketplace for current release estimates). That being said, it probably elimintes WDA as a possiblity for your project unless you are will to wait and to upgrade.
However having worked with WDA for a while it is probably the best tool to custom develop what you describe. It has excellent built-in F4 value help. It also has a damn fine ALV grid implementation. The spreadsheet could be just as simple as file upload in binary or your could try your hand at office integration. Finally for the form you could use Adobe Interactive Forms which also has very nice integration into WDA.
Now to Dialog Programming: You could of course use dialog programming. It seems a little bit of a waste to custom build something so large if WDA is in your near future. There are obvious disadvantages (little OO structure, no MVC, etc). You would have ALV grid, office integration and of course F4 help. You could still use Adobe forms if you implement this on the 640 system. However there are integration points with dialog and Adobe Interactive Forms. You could still use printed forms however. If you did the dialog program on the 640 system, you could use the integrated ITS to expose it to the web. The integrated ITS in my experience has quite nice performance although the look and feel remains just like the SAPGui.
The Java Webdynpro route: Well you hit the nail on the head - if you don't have a Java programmer already and you don't have the bandwidth to invest in learning Java, this can be a problem. The Java Webdynpro environment is quite nice. There are some things I like better than ABAP and some things that ABAP is defintely still better at. However when it comes to heavy integration with an ABAP backend - ABAP Webdynpro is still the way to go. Java Webdynpro does have a help feature (OVS), but it isn't "for free" or nearly as nice as the ABAP Webdynpro (perhaps it will get there some day). That is one of the major advantages of WDA - its closeness to the business data brings several framework advantages like F4 and field help. WebDynpro Java in 640 also doesn't have an ALV grid implementation. I am sure that this is something both environments will eventually have, but right now ABAP has the advantage. On the other hand, Webdynpro Java has equal support when it comes to office integration, file upload, and Adobe Forms support. You would have a more difficult time integration SmartForms however.
Finally we come to BSP. Honestly if I were in your position I would probably choose BSP (unless you could wait for the ABAP Webdynpro upgrade). You could build a nice MVC OO application using BSP (stateful or stateless). The BSP product is mature and quite well documented thanks to SDN. You have the BSP Extensions which when used in Design2003 use the Unified Renderer. That means that your output will look nearly identical to the same UI elements in Webdynpro. Also BSP supports portal integration (session management, eventing, and themes).
The downside to BSP is that it isn't a full framework (also one of its advantages). You can insert all your own html and javascript (unlike webdynpro). But this also means that SAP doesn't delivery as many framework services. For instance there is no ALV or Value Help. There is no Office Integration or Adobe Forms integration. There is some farily good Smart Forms integration. Now the upside- many people have already hit these limitations and overcame them. In the weblogs on SDN and in a certain SAP Press book (cough, cough) you will find out of the box solutions for many of these problems. You can find ready to use solutions for Adobe Integration, Office Integration (using Microsoft Office Web Controls), and F4 help. It will mean investing a little more time up front to get this "home grown framework" up and running - but it is perfectly feasible.
There is a learning curve to all these new technologies however. This sounds like an abmious project. I wouldn't want to try and tackle this project in any of these technologies if I was new to them. With Webdynpro or BSP - consider giving yourself time to learn the environment and cut your teeth on some demo apps before jumping into such a huge development.

Advantages of ABAP Webdynpros over BSP??

Hi,
We are currently in ECC6.0. Is ABAP Webdynpro advantageous over BSP for any UI development ECC6.0 onwards in general?
Specific requirement for which BSP is needed - we need a single application for a Help Desk team to handle calls from customers. The application will have multiple screens with data flowing into this application from multiple sources.
Need inputs on the above....
TIA,
Regards
Deepthi

>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 call the functions via an RFC interface called a JCo connection.
There are many incorrect statements in your posting. You appear to be compairing BSP to Web Dynpro Java - not Web Dynpro ABAP. Why would you do this in a Web Dynpro ABAP forum posting? Of course everything you stated about Web Dynpro running on the Java engine and using JCo and being programmed in the Java development workbench is totally wrong if you are comparing to Web Dynpro ABAP.
Here is the explaination of the differences from the SAP Press Book: Next Generation ABAP development (page 303):
Web Dynpro ABAP is SAPu2019s new UI strategy, which was introduced in SAP
NetWeaver 7.0. It is based on the Model View Controller (MVC) paradigm
that separates business logic from the user interface logic. Developers, like
Russel, can use this tool to develop robust business applications quickly and
easily, without ever having to deal with the inner coding of the user interface
elements.
The Web Dynpro ABAP framework provides a WYSIWYG view editor (What
You See Is What You Get) where the developer simply drags and drops the UI
elements into the view. This means that there is no coding of the UI elements.
This is not the case when working with Business Server Pages (BSP),
where the developer must know some HTML or JavaScript in order to code
the user interface.
The Web Dynpro framework approach can be viewed in a number of ways.
If a developer is not proficient in HTML or JavaScript, the Web Dynpro
ABAP tool looks pretty good. He doesnu2019t have to worry about coding the UI
and he can focus more on the business application logic. On the other hand,
if the developer wants to add his own look and feel or some additional UI
functionality to the Web Dynpro ABAP UI, he canu2019t. The UI implementation
is hidden from the developer and cannot be manipulated, such as adding
your own HTML or JavaScript. The reason for this protection is that Web
Dynpro was developed to provide a standard business application user interface
across all applications that leverage this tool.
There is another advantage to the client abstraction approach that Web Dynpro
takes. When you design a user interface in Web Dynpro, what is saved is
just a metadata representation of the layout and elements. In other words,
Web Dynpro is not tied to just HTML and JavaScript as its output medium.
The Web Dynpro runtime analyzes the type of client that is making a request and responds with the appropriate rendering output. Today that means web browsers are making the request and receiving HTML and JavaScript. But, in the future, when the next great UI revolution occurs, you wonu2019t necessarily
have to recreate your applications to take advantage of it. Already you can see examples of a smart client and Adobe Flex based rendering engines for Web Dynpro. Switching to these alternative presentation tools requires no coding changes within the applications themselves.

Calling an ABAP WebDynpro Popup from a BSP view

I need to know if the following is possible.
I have a requirement to call an ABAP WebDynpro Popup from a BSP view.
When the Popup is triggered (eg via pushbutton) the BSP will pass data to the Popup, before the Popup is closed the Popup will pass data back to the BSP to be displayed in the BSP view.
I do not want to rely on Portal Events as Portals may not be used, would really appreciate a clean simple solution.

Hi,
any webdynpro application has a URL behind it. Haven´t you tried to call that URL with Javascript code ??
script language="Javascript"
url = "test_page.htm" + "?field=" + param;
window.open(url, "F4window", "width=400, height=400");
/script
You can pass data to the WD application using parameters as I show you after the "?".

Calling a BSP application in ABAP webdynpro

Hi Friends,
Is there any chance that i can call a BSP application from WEBDYNPRO.
regards
Nalinikanth.

Hi Yashpal/ Pankaj,
I have one question regarding this.
The usage of the UI element link "link to URL" is pretty much understandable to call a stanalone application.
Whereas the usage of suspend and resume plugs, how does it work for BSP applications? For two WD components we can connect the plugs and it works.
As I do not know about BSP, does it have in/out plugs like WD components?
If so how to create the navigation link for this.
Please explain.
Sankar.
