ABAP(R3) call to Portal(Webdynpro)

Hi experts,
I have a requirement to initiate a call from an ABAP program on R3 to a standard Portal (Webdynpro) API. Does anyone have any experience with this?
I understand that normally Portal (Webdynpro) applications will make the RFC call to ABAP via the established JCO connection. However there's very limited literature elaborating how the call can be made in the other direction i.e. from ABAP R3 to Portal
Anyone, please kindly advise how, if this can be done. Many thanks!
Best regards,
Lionel

Calling an Portal Webdynpro iView from another Webdynpro iView - Error

Hi,
I have modified the DefaultFramework Page by adding an Alert iView (based on WebDynpro) and assigned this modified framework page to all users. It works fine.
The Alert iView on the Left hand side (right above the Detailed Navigation) consists of links to different WebDynpro iViews in the same Portal.
I have used LinkToAction UI element, on event of click
i am executing this piece of code.
onActionClick (com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent)
WDPortalNavigation.navigateAbsolute("ROLES://portal_content/folders/X.Iview", WDPortalNavigationMode.SHOW_INPLACE, (String)null, (String)null, WDPortalNavigationHistoryMode.NO_DUPLICATIONS, "Called iView Name", (String)null, (String)null);
I have picked up the iView name from the Portal(exact PCD location).
It is not working. Once in a while it worked. But now it is not loading at all.
Please let me know your thoughts on the same.
Thanks
Senthil

Hi,
Got it solved. User has authorization to execute the page.Their roles were not added in Permission list of that Page.
Added the roles. Now it works fine.
Thanks

Calling a portal page from WebDynPro ABAp application

Hi,
I would like to call a portal page (any type) from a WebdynPro ABAP application. I have the PCD location of the page.
Which call shall I make :
Absolute Navigation
Relative Navigation or
OBN.
Also, can anyone send me short code snippet on the following.
The package SWDP test examples are not working.
Best Regards
Sid

Hi Siddharth,
Well, to start with you can go for ABSOLUTE NAVIGATION.
Secondly, you can find the snippet here
DATA LO_API_COMPONENT TYPE REF TO IF_WD_COMPONENT.
DATA LO_PORTAL_MANAGER TYPE REF TO IF_WD_PORTAL_INTEGRATION.
DATA L_NAVIGATION_TARGET TYPE STRING.
LO_API_COMPONENT = WD_COMP_CONTROLLER->WD_GET_API( ).
LO_PORTAL_MANAGER = LO_API_COMPONENT->GET_PORTAL_MANAGER( ).
MOVE 'pcd://portal_content/com.xxxx.zpof_f_XXXXportalcontent/com.xxxx.test/com.xxxx.folders.MaintenanceBusinessPackage/com.xxxx.test.mt.pages.Pages/com.xxxx.pages.MaintenanceTasks'
 to l_navigation_target.
CALL METHOD lo_portal_manager->NAVIGATE_ABSOLUTE
 EXPORTING
 NAVIGATION_TARGET = L_NAVIGATION_TARGET
* NAVIGATION_MODE = IF_WD_PORTAL_INTEGRATION=>CO_SHOW_INPLACE
* WINDOW_FEATURES =
* WINDOW_NAME =
* HISTORY_MODE = IF_WD_PORTAL_INTEGRATION=>CO_NO_DUPLICATES
* TARGET_TITLE =
* CONTEXT_URL =
* POST_PARAMETERS = ABAP_FALSE
* USE_SAP_LAUNCHER = ABAP_TRUE
* BUSINESS_PARAMETERS =
* LAUNCHER_PARAMETERS =
Above it, the examples of SWDP will not work if you test them from SE80-ABAP WAS...I suggest you to create a WDA IView in Portal and test it in Portal itself.
Hope this should solve your problem.

Hi,
I have to call a portal iView from the WD ABAP application.
The iView root is e.g.
folder1/folder2/check_workset1/iView
How can we call it using Absolute navigation or Relative Navigation.
I just want to call this path.
Can anyone provide me with a code snippet.
Best Regards
Sid

Hi ,
I am calling the following method in my action call of a Webdynpro ABAP View
CALL METHOD lo_portal_manager->NAVIGATE_ABSOLUTE
EXPORTING

The webdynpro/ABAP (WDA) calling RFC enabled FM of other ECC systems

The webdynpro/ABAP (WDA) has problem calling RFC enabled FM of other ECC systems.
WDA expects all the ABAPs, RFC FMs of remote system(DEV, QA..) to reside inside its own instance.
It is hard to transport and maintain these ABAPs FMs into a portal ABAP WDA instance.
Proxy generation at WDA client:
=======================
1. If we can make an XI enable an ABAP or RFC enabled FM of the remote ECC,
I think the XI proxy classes can be generated at the client WDA system.
Other options?
How do I do it? Can you give some tips.
2. How do I manually code the RFC Call to BAPI/FM from Webdynpro controller or other interface?
I am stuck with the above as the webservice option is not available at our ECC server. It does not have a java engine installed for webservice to be available.
Can you help on the above 2 options?

Hi Mike ,
 Answer of 2.
How do I manually code the RFC Call to BAPI/FM from Webdynpro controller or other interface?
I am doing same thing for my current SRM implementation.I am taking data to SRM server from another R/3 server .
This is solution I have used
1) First of all I have made ABAP connection in SM59 .
Go to SM59 .In ABAP Connection creat ABAP connection with system with which u want communicate .
Eg I am connection with Systems PB1.
So i developed Connection call PB1CLNT800.
2) In my requirement I have taken data in my context from another r/3,
I have give called RFC in my supply function of node.
Call to RFC is as usual.
In my case,
CALL FUNCTION 'RFC_MATNR'
DESTINATION 'PB1CLNT800'
TABLES
IT_MATNR = IT_MATNR.
Onwards I have read my itab IT_MATNR and populated data to context.
Hope solution will serve your purpose.
Give point if it works .If any problem i have other ways.
Cheers

Calling GuidedProcess from WebDynpro ABAP

Hi all
can anybody tell me that how to call GP from webdynpro ABAP.
and what are the advantages and disadvantages in this scenario??
if anyone reply then it would be the great help to me
Regards
Suresh babu

Hey,
You can call a GP from WD ABAP through by implementing a service call from a method that is embedded in your WD. You can refer this link for the same.
http://help.sap.com/saphelp_nwce10/helpdata/en/44/58f9cc0d95311ce10000000a155369/frameset.htm
But you should note here that Data exchange between ABAP WD and GP is not two way but its only one way.

Call a Portal Application from WebDynpro

Hi experts,
i hope you can resolve my problem!
My intention is to refresh the browser and call the first page of the portal after the portaluser pressed a button in an WebDynpro application.
For this purpose i create a portal application with an JSPDynPage and an JSP how call the JavaScript Method "top.location.reload();".
My question:
How can i call an portal application in a WebDynpro onAction Event?
Thanks,
Florian

1)Creat one action method "ReactPortalEventing" with the parameter dataObject and write the code in wdDoInit method as
//the urn and method name like "sendEvent" both should be same
WDPortalEventing.subscribe("urn:com.abc.practice","sendEvent",wdThis.wdGetReactPortalEventingAction() );
2)and in the action method display the name as
wdComponentAPI.getMessageManager().reportSuccess("Event value"dataObject);
also chk it

       1. webdynpro ABAP application development and
       2. webdynpro ABAP application integration with enterprise portal.
Thanks...

hi Kundan ,
design pattern or paradigm followed by Webdynpro ABAP is
MVC concept
           M-Model
           V- View
            C-Controller
and cms with the advantages like Structuring the programming
     Creation of easily manageable application blocks
     Reusability of whole components

RFC Call to Portal Service

Hi
I am trying to call a Portal Service from the SAP R/3 through RFC.
I have done the following.
1. Created RFC in the SAP R/3.
2. Created RFC Destination in SAP R/3 and WAS 640
3. Created a Portal Service and deployed in the Portal.
The problem is when I execute the RFC in ABAP it is giving me this error.
com.sap.engine.services.ejb.exceptions.BaseRemoteException: Exception in method processFunction
As anyone faced similar problems, please let me know.
Regards
Senthil

Hi Senthil,
If you haven't already done so, I think you should try this question in the 'ABAP Programming' forum.

RFC call from java webdynpro

Hi,
I'm creating a Java Webdynpro where I call RFC's from SAP.
For the images in the webdynpro, I call the standard SAP function 'CVAPI_DOC_VIEW'
When I execute the function in SAP, I get the url to the contentserver with the correct image.
After calling the same function in my Java Webdynpro, the url is empty.
I've checked the importing parameters after calling from webdynpro and SAP and they are the same.
After debugging, I saw that the function 'CVAPI_DOC_VIEW' is the problem. He's exporting an empty url after calling from the webdynpro.
Does anybody knows the possible fault and solution for my problem?

I'm not an ABAPer but the last time I've dealt with DMS from Web Dynpro an ABAPer wrote a custom function that gets the file content (XSTRING) by sending DMS parameters (documenttype, documentnumber, documentversion, documentpart).
After getting the XSTRING from my Web Dynpro Java, I convert it to byte[] and created URL by using WDResourceFactory.
Hope it helps...

Calling a Portal Service from within a Web Dynpro DC

Hello,
I am trying to call a Portal Service from within a Web Dynpro development component without sucess.
Can anyone give me some hints on the necessary steps in order to accomplish this task?
Thanks
Diz

Hi Diz,
I tried doing the same thing by following the steps as mentioned by you. Just to re iterate,
1. Created a DC "Portal Application Standalone" project by the name myservice.
2. Created a portal service inside myservice by the ame AmitsService.
3. Exposed IAmitsService.class in the public part.
4 Build and deployed the DC on server and tested it through an abstract portal component and it worked FINE !!
Now..
5. Created anoter DC of type WebDynPro
6. Added SAP_JTECHS -> epbc.prtapi._api as a "Used DC" with dependency build time and runtime
7. Specified the sharing reference in the properties as PORTAL:sap.com/myservice
8. Tried to reference the service using the following code..
IAmitsService portalservice=(IAmitsService)WDPortalUtils.getServiceReference(IAmitsService.KEY);
9.Build and deployed the DC.
10. When I run the application I am getting the following error
Processing HTTP request to servlet [dispatcher] finished with error.
The error is: com.sap.engine.frame.core.load.SAPNoClassDefFoundError: com/sapportals/portal/prt/service/IService
Exception id: [000D6008418B005C0000002C00000D200004163CE6719E1D]

Web Dynpro ABAP...to Portal

Hi Friends,
My question is......is it possible whatever I develop in Web Dynpro ABAP to publish it to portal which is on different server with different SID?
Thanks,
Rajeev Sharma.

ABAP WebDynpro are developed on WAS which has ABAP stack. Portal typically has j2ee engine (java stack) and you only create iViews pointing to the ABAP WebDynpro. There is no deployment on portal unless you have ABAP stack on your portal server.

Calling RFC with webdynpro java (in NetWeaver Developer studio)

Calling RFC with webdynpro java (in NetWeaver Developer studio)
Hi,
I want to call only one parameter RFC with webdynpro.
Flight example is very complex.
I want to push a button and pass parameter to RFC input and call RFC.
After execution some message must appaer on the screen.
Is there a step by step .pdf?
Thanks.

Hello Cemil,
There's a seperate Web Dynpro forum for such posts, you should take a look there.
Nonetheless, the classic tutorial is the FlightList. If I was you, I would make sure to do this tutorial step-by-step as it should give you the fundamentals for understanding aRFC. On top of that, it's most likely already available to you on your SAP system...
Here's the link:

I´m working just with EP 7.01 (EHP1) (there´s not any ABAP System in the Portal Landscape).
I searched for PeopleFinder.xml in the server file system* (it´s the value of com_sapportals_wdf_ConfigFileName property) and nothing was found, so I think that´s the problem but I couldn´t find so much about it.
Thanks a lot for your time on this thread.
Rocío.

Hi Rocio,
Is this just a regular AbstractPortalComponent iView you have written? What are you trying to do in the code? I don't see any non-sap classes in the error stack only com.sap.*
Is the PeopleFinder.xml file a file that you have included in the PAR?
BRgds,

I cannot figure out whare and how to put the portal KM URL Link into the web application web link.
Your help is greatly appreciated.
Thanks
Karen

Add content administration role to the user.
The the content administration tab would be visible to the user in the main menu tab.
Then in content administration tab, configure the URL for KM URL tab or link.
This would be done by EP experts. Please contact your EP experts to do.
Hope this would help you.
