Standard Transaction Vs Webdynpro ABAP development in Portal ?

Hi All ,
I just need to know that if we do some kind of enhancement/modification in sap standard screen using the classical tools like screen painter etc. when we deploy these transaction on portal we will have those changes on the web based GUI or we need to developed the whole new development for that transaction to show on the portal ?. I know webdynpro for ABAP can be used for new developments but what if we just need a simple change on screen and we can achieve the goal using simple screen enhancement ? do we need to develop the screen again in webdynpro ? Kindly can anybody explain this ?
Thanks a lot in advance.

SAP ABAP screens are used by SAPGUI for Windows and SAPGUI for HTML and are presented exactly as the screen designer lays them out. The portal can start either SAPGUI variant.
WebDynpro has nothing to do with existing SAP ABAP screens. You build new screens and then call BAPIs etc to populate the fields.
The portal can start a Web Dynpro application.
To change the look of an existing SAP ABAP screen you need to change the screen. If you want to completely change the screen, start building Web Dynpro programs.
Cheers

Starting Webdynpro ABAP development

Dear Experts,
I am a Portal Consultant and I know Webdynpro Java. I am planning to learn Webdynpro ABAP.
Could you please provide me the details about actual Webdynpro ABAP development?
I have seen some applications and they used "Service Call" method to execute BAPI's and setting Import parameters.
In some applications they used normal development.
Could you please provide which is suitable( through Service call or normal development) and majarity of the people can use?
Thanks & Regards,
Vijay

Hi Vijay,
Service call is required basically to get data from systems other than the calling systems i.e. a RFC call. Though you can use BAPI's to get data from the same system. (FM must be RFC enabled to use this functionality)
You can also call normal FM, but for that you don't have to create a service call.
Suppose if you want to use some standard BAPI's or FM just by creating service call you can use in your application.
check this example how to use BAPI,

Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input

Dear Friends,
We are facing a serious problem for debugging. Expecting valuable input for the same.
Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input in Production Server.
The debugging (for WebDynpro-ABAP application) is working in Dev. Server for
1st ] Within R/3
Ex. debug for bapi within R/3. i.e. value enter as input in R/3 only.
2nd ] From webpage to R/3
Ex. Some input given on the internet web page developed through WebDynpro and external breakpoint set in R/3 it works. It directs to R/3 code through debugging.
In Prod. Server the 1st case above is working but the 2nd case is not working.
In Prod. Server the WebDynpro developed applications are running successfully through internet explorer webpage inputs. So running the application is not a problem in prod. Server but debugging of the same is the problem.
The setting which are done in Prod. server are,
1] RZ10 in parameters are set for port and host name.
2.1] In SMICM check for ICM.
2.2] Host file updated in Windows-System 32.
3] In SICF following services are active,
3.1] default_host/sap/bc/webdynpro
3.2] default_host/sap/public/bc
3.3] default_host/sap/public/bc/webdynpro/viewdesigner

3.5] default_host/sap/public/icman
3.6] default_host/sap/bc/gui/sap/its/webgui
3.7] default_host/sap/public/ping
3.8] default_host/sap/bc/error
3.9] default_host/sap/bc/echo
4] In SE80
4.1] Internet services-System-are published
4.2] Internet services-WEBGUI-are published
4.3] Utilities-Setting-ABAP Editor-Debugging-Username & New Debugger set.
4.4] Utilities-Setting-ABAP Editor-Editor-Front-End Editor(New) set.
5] In Su01 for user profiles sap_all & sap_new is assigned and role SAP_BC_WEBSERVICE_DEBUGGER is assigned.
6] The support packages are also updated to latest level.
7] Gone through following links but not getting any clues.

How to deploy the webdynpro ABAP application in Portal

Hi,
Can someone provide me, all the steps involved to deploy the webdynpro ABAP application in Portal.
Thanks,
Kundan

Hi Kundan,
First create a WD abap component and then you have to integrate in the portal.
Refer this article [Integrate a Web Dynpro Application into the SAP Enterprise Portal|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/7bfea990-0201-0010-44a7-84a74971b795&overridelayout=true].
I hope it helps.

Include SAP standard transaction screen in ABAP webdynpro view?

Hi all,
Any body have idea on how to create SAP transaction screen in WebDynpro view?
ex : i have requirement like i need IB52 transaction in webdynpro view, so that it will be called this view from EP iview to do some process.
Regards,
Rajesh Yadla

Hi,
you can use a IFRAME and run a Portal transaction Iview for IB52 inside the WD-IFRAME.
For that you first have to create an iview for the Transaktion IB52 inside your Portal.Then call the preview of the Iview. This Preview-URL(or the PCD) you can call as source inside the WD-IFRAME. For me this works fine.

Frank

Apply custom themes to WebDynpro ABAP application in Portal

Hi,
We have just upgraded the E-Recruitment to EHP4. We have two instances of ECC in which one acts as HR instance and the other one for E-Recruitmet. We have created custom themes for portal and need to apply the same for the WebDynpro ABAP applications for E-REcruitment. I have downloaded the theme and from portal and uploaded the same in MIME folder using SE80 transaction. I have also added the parameter sap-cssurl=/sap/public/themes/<my custom theme folder name>.
Also tried giving the url in application parameter as
SAP-EP-THEMEROOT=http://<hostname>/irj/portalapps/com.sap.portal.design.portaldesigndata/themes/portal/customer/<custom theme>
Is there any other way to apply themes for WD ABAP applications. I dont want to customize the standard applications and just want to apply the themes.
Any suggession on this is highly appreciated.
Kind Regards,
Vivek.

Hi,
to create theme for webdynpro abap application, use Eclipse Plugin. Please remeber to check the version of theme file before using theme.

Webdynpro ABAP from enterprise portal

Hi,
We have an portal which can be accessed from internet through webdispatcher. Now we have developed certain Webdynpro ABAP based based application in (R3). The WD ABAP iviews are been created on portal. But we are not able to access this application when portal is opened from internet.
The R3 is not available on internet. So how can we manage these thing so that Webdynpro ABAP can be accessed from internet?

First of all let me clear few misconceptions created from above replies.
1. You dont need public IP address for your R/3. All you need is R/3 should be accessible to webdispatcher.
2. While opening ABAP Webdynpro/ITS iviews through portal, its not portal which is trying to communicate with backend. Its the browser who does this. You can see this through http trace at browser.
It is due to 2 that your ABAP webdynpro are blocked. Bcoz no one will open R/3 to internet. Probably its blocked at firewall. Its a security issue.
For ABAP WD,
Browser > Webdispatcher > R/3.
This is how it is designed.
This is very common problem and you will find many discussions in sdn regarding this.
You can either convince your security team that R/3(ICF) should not be blocked. For which they would never agree.
Another option could be create a virtual host at R/3 and create webdynpro services(ICF services) in this virtual host and specify this virtual host in your webdispatcher.
Another expensive option could be create a Webdynpro runtime engine(WEB AS ABAP) where webdynpro applications should run and they do an RFC call with R/3. I am sure security ppl would love this.
It becomes Browser > Webdispatcher > WD runtime >(through RFC) R/3.
Thanks,
Nag

ABAP development thru portal

I am not sure if this is the correct forum to post this but I could not think of another one to post into. Our company wants to start using the portal to for accessing SAP as opposed to fat client. I am trying to work with se80 and I find that it is not as good as the fat client. one thing I am finding is that when to click on a function, in the fat client you would be taken to the code for the function but in the portal it does not. It seems like delevoping thru the portal would really be a challange. Is anybody doing development thru the portal? are there tricks that you do or is there special setup that you do in order to do development?
thanks in advance for your help

Hi,
The Portal is meant to replace the SAP GUI from the user's standpoint. The idea is that users would be able to access all applications (SAP or non SAP) through a single (web-based) user interface instead of having to log on individually to each of the systems.
However, this does not apply to the developers. Developers will still have to do ABAP development using the SAP GUI and dynpro development using the NWDS (for Java Web Dynpro) and SAP WAS (for ABAP Web Dynpro). This is not going to go away.
Hope this helps in clarifying your doubts.

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

Exit from Webdynpro abap application in portal environment

Hi,
I created one custom service in Webdynpro ABAP in ESS and also integrated in the portal environment
I need to put Exit button in every page ( OVERVIEW, EDIT, REVIEW). When user click on 'EXIT' button from any one of page , it should return back to PERSONAL INFORMATION in ESS Homepage.

Putting Webdynpro ABAP application on portal

Hi all,
We have SAP ECC 6.0 as the ABAP system and EP 7.0 SP 6 is the portal. I want to show a Webdynpro ABAP application on the portal which I have created in the ECC system.
I have an created an application in the back end with the following parameters :-
Webdynpro Component name :- ZTESTWEBDYNPRO
Webdynpro Application name :- ztestwebdynpro
I then created a Webdynpro ABAP iview with following parameters :-
Application name :- ztestwebdynpro
Namespace :- sap
System :- SAP_ECC_SERP (this has been tested and is working).
We also have SSO configured with logon ticket to the ECC system.
But I am getting a "Page cannot be displayed" error when I execute the application.
Any idea why this can occur?
Thanks,
Hari

Hi Hari,
So assuming you have tested the connection to the system,
perhaps another service, BSP, ITS , whatever
and that it is creating WEB DYNP ABAP iviews that is the drama.
Under EP 7.0, be sure to choose Iview type WEB Dynp ABAP.
the properties page with application parameters is:
SYSTEM -> As created to access system, available in dropdown
Namespace - > sap
Application name ->     <your WDA>    case as created in SE80
So it looks like you have entered correctly to me.
Perhaps the portal Forum has more info if you have continued issues.

Phil.

Implementing WebDynpro ABAP in JAVA Portal

Hello
We have a JAVA enterprise Portal and we would like to create an iView of WebDynpro ABAP application.
We have done it in our QA portal by creating a system and in the property editor configuring the "Web AS Host Name" & "Web AS Path".
It works great becuase there is only one ABAP application server.
However, in Productoin we have several ABAP application server and one central instance.
If i create a system using template and choose "SAP system with load balancing" , still In the property editor i see only "Web AS Host Name" .
How can i set in the system's property editor a group of servers that hold WebDynpro ABAP application ?
Does anybody have a clue ?
Adi J.

Hi Adi,
For load balancing purposes you should use the SAP Web Dispatcher. The Web Dispatcher will know all you web application servers and will redirect the requests to the app server with more resources available.
Thus you can set the Web As hostname and port to the Web Dispatcher.
You should avoid using the message server for load balancing purposes. I can suggest you the following SAP notes for further information:
1225587 - WebDynpro ABAP with Loadbalancing in the Enterprise Portal
1040325 - HTTP load balancing: Message Server or Web Dispatcher?
945516 - Web Dynpro ABAP in a portal environment
I hope this helps.

Cristiano

ESS/MSS custom services or modify standard service with WebDynpro Abap

Hi all,
what's the procedure to modify standard ESS/MSS or create new service with WebDynpro Abap.
Thanks.
Miki

Hi
First, The ISR Scenarios are not for iviews. They are just a part of a view. We can use webdynpro ABAP with the ISR Scenarios. We need to embed these forms into our webdynpro ABAP views and code accorsdigly to get the data. There are some standard components that are provided by SAP to handle ISR Forms with Webdynpro. Check these.

Debugging the webdynpro abap application from portal.

I developed a WebDynpro application and integrated in portal. I have to catch some portal events.For that i have written some code in my application. I tried to debug the application from portal by using all the available break-point types.but we could not .
Anybody have an idea how to debug a WebDynpro application from portal.
Thanks,
Kumar.

Hi
Few links to check:
External debugging is not working
Re: Debugging Abap webdynpro appln
Re: Unable to Debug WD ABAP application
Dedug is not working in Production Server.
a) Check on number of R/3 sessions opened at a time.
b) Check that user ID configured in portal using System Mapping Under 'Delegate User Administration' is the same user for which you are setting external breakpoint in backend system.
