How to call ABAP transaction from Webdynpro in NWBC

Hi
I need to develop an Webdynpro application who lists Sales Orders. The Application is launched in NWBC DESKTOP version.
This part is no big deal...
But: i need to gain users the possibility to display the Sales Orders in T-CODE VA03 (ABAP) when they click a link in the list. How can i do that?
I have tried to do a test like this:
method ONACTIONTEST_LAUNCH .
DATA: url TYPE string,
        query TYPE string.
url = cl_nwbc=>url_construct( html_client        = abap_false
                                canvas_transaction = 'VA03' ).
cl_nwbc=>url_launch( url ).
endmethod.
But this url launches the HTML version of NWBC (inside the Desktop version...). and i want the system to launch the ABAP system.

Hi Jakob,
I would use Object Based Navigation in this case (OBN). With OBN you can define an OBN target in your WDA application and map that target to a transaction in your PFCG role.
Here is some help

How to call a webService from WebDynPro ABAP ?

We are trying to call a webService from WebDynPro-ABAP application. It is not working, While if we are calling the WebService from a Report, it is working.
How exactly do we call a WebService from a WebDynPro-ABAP application?
What are the main steps involved ?

Hi Phani,
You will need to create a service call as follows.
Right click on your WD component name and select Create->Service Call
The wizard will guide you through a series of steps to make a Web Service Call. On the 3rd screen, it will give you options such as Function Module, Web Service, etc
Before making a service call, you will need to create a proxy for the Web service in the ABAP Workbench using a WSDL document as a basis. To create or consume Web services, you will need the authorizations associated with the role SAP_BC_WEBSERVICE_ADMIN.

How to call a transaction from ABAP code

Hi everybody,
How do I run a transaction from my ABAP code?
For example, through my ABAP code, I want to call the ME24 transaction (Maintain Purchase Order).
Thanks for the help,
Roy

CALL TRANSACTION
Syntax
CALL TRANSACTION ta { [AND SKIP FIRST SCREEN]
                    | [USING bdc_tab [bdc_options]] }.
Extras:
1. ... AND SKIP FIRST SCREEN
2. ... USING bdc_tab [bdc_options]
Effect
The statement CALL TRANSACTION calls the transaction whose transaction code is contained in data object ta. The data object ta must be of character type and must contain the transaction code in uppercase letters. If the transaction specified in ta cannot be found, an untreatable exception is triggered. The additions suppress the display of the initial screen and allow you to execute the transaction using a batch input session.
At CALL TRANSACTION the calling program and its data is kept, and after exiting the called transaction, processing is resumed in the calling program after the call.
When the transaction is called, the ABAP program linked with the transaction code is loaded in a new internal session. The session of the calling program is kept. The called program runs in an SAP LUW of its own.
If the called transaction is a dialog transaction, after loading the ABAP program the event LOAD-OF-PROGRAM is triggered and the dynpro defined as initial dynpro of the transaction is called. The initial dynpro is the first dynpro of a dynpro sequence. The transaction is finished when the dynpro sequence is ended by encountering the next dynpro with dynpro number 0 or when the program is exited with the LEAVE PROGRAM statement.
If the called transaction is an OO transaction (as of release 6.10), when loading all programs except class pools the event LOAD-OF-PROGRAM is triggered and then the method linked with the transaction code is called. If the method is an instance method, implicitly an object of the corresponding class is generated and referenced by the runtime environment. The transaction is finished when the method is finished or when the program is exited using the LEAVE PROGRAM statement.
After the end of the transaction call, program execution of the calling program resumes after the CALL TRANSACTION statement.
Note
At the statement CALL TRANSACTION, the authorization of the current user to execute the called transaction is not checked automatically. If the calling program does not execute a check, the called program must check the authorization. To do this, the called program must call function module AUTHORITY_CHECK_TCODE.
Addition 1
... AND SKIP FIRST SCREEN
Effect
This addition suppresses the display of a screen of the initial dynpro of a called dialog transaction. The addition AND SKIP FIRST SCREEN suppresses the first screen under these prerequisites:
For the initial dynpro, in the Screen Painter the own dynpro number must not be specified as the next screen number.
All mandatory input fields of the initial dynpro must be filled completely and with the correct values by the SPA/GPA parameters
If these prerequisites are met, that screen of the dynpro is displayed that is specified in the Screen Painter as the next dynpro of the initial dynpro.
Example
If the static next dynpro of the initial dynpro of the called dialog transaction FLIGHT_TA is not the initial dynpro itself, its screen is suppressed, because its input fields are filled using the SPA/GPA parameters CAR and CON.
DATA: carrid TYPE spfli-carrid,
      connid TYPE spfli-connid.
SET PARAMETER ID: 'CAR' FIELD carrid,
                  'CON' FIELD connid.
CALL TRANSACTION 'FLIGHT_TA' AND SKIP FIRST SCREEN.
Addition 2
... USING bdc_tab [bdc_options]
Effect
Use this addition to pass an internal table bdc_tab of row type BDCDATA from the ABAP Dictionary to a dialog transaction. The additions bdc_options control the batch input processing. When a transaction with addition USING is called, the system field sy-binpt is set to value "X" in the called program - while this transaction is running, no other transaction can be called with this addition.
The internal table bdc_tab is the program-internal representation of a batch input session and must be filled accordingly. The structure BDCDATA has the components shown in the table below.
Component Description
PROGRAM Name of the program of the called transaction
DYNPRO Number of the dynpro to be processed
DYNBEGIN Flag for the beginning of a new dynpro (possible values are "X" and " ")
FNAM Name of a dynpro field to be filled or batch input control statement, for example, to position the cursor
FVAL Value to be passed to the dynpro field or to the control statement
Using the internal table bdc_tab, you can provide any number of screens of the called transaction with input and user actions.
System Fields
sy-subrc Description
0 The batch input processing of the called transaction was successful.
< 1000 Error in the called transaction. If within the transaction a message was sent, you can receive it using the addition MESSAGES.
1001 Error in batch input processing.
Note
Outside of ABAP Objects you can specify the additions AND SKIP FIRST SCREEN and USING together. However, this does not make sense, because the addition AND SKIP FIRST SCREEN is desigend only to fill the mandatory input fields using SPA/GPA parameters, while the batch input table specified with USING controls the entire transaction flow including the display of the screens.
Example
Call of the Class Builder (transaction SE24) and display of class CL_SPFLI_PERSISTENT. The internal table bdcdata_tab contains the input for the batch input processing of the first dynpro (1000) of the transaction. Using structure opt, the batch input processing is set to suppress the first screen and to display the next screen in the standard size.
DATA class_name(30) TYPE c VALUE 'CL_SPFLI_PERSISTENT'.
DATA: bdcdata_wa TYPE bdcdata,
      bdcdata_tab TYPE TABLE OF bdcdata.
DATA opt TYPE ctu_params.
CLEAR bdcdata_wa.
bdcdata_wa-program = 'SAPLSEOD'.
bdcdata_wa-dynpro   = '1000'.
bdcdata_wa-dynbegin = 'X'.
APPEND bdcdata_wa TO bdcdata_tab.
CLEAR bdcdata_wa.
bdcdata_wa-fnam = 'BDC_CURSOR'.
bdcdata_wa-fval = 'SEOCLASS-CLSNAME'.
APPEND bdcdata_wa TO bdcdata_tab.
CLEAR bdcdata_wa.
bdcdata_wa-fnam = 'SEOCLASS-CLSNAME'.
bdcdata_wa-fval = class_name.
APPEND bdcdata_wa TO bdcdata_tab.
CLEAR bdcdata_wa.
bdcdata_wa-fnam = 'BDC_OKCODE'.
bdcdata_wa-fval = '=CIDI'.
APPEND bdcdata_wa TO bdcdata_tab.
opt-dismode = 'E'.
opt-defsize = 'X'.
CALL TRANSACTION 'SE24' USING bdcdata_tab OPTIONS FROM opt.

How to call ABAP programs from Excel

Hello everyone,
Currently I'm investigating the integration of Excel and ABAP program. I find it's easy to call Excel from ABAP program, but does anyone of you know how I can first open and do some actions in an Excel sheet first, and then, for example, when I press the save button, the data will be transferred back to ABAP system? I think when openning the Excel, the logon of the backend system is needed.
I've ever seen this functionality in some BW-reporting tools, but I cannot remember the details.
Thank you very much and best regards,
Leon

yes in BW we are having this concept of creating wookbooks & queries.
If u have BW server Go to Transaction RRMX - u will get a Microsoft Excel sheet.
Here it allows u to logon to the SAP system.
For details see this link.

How to call report program from WebDynpro Application

HI
How call report program in WDA.
1. To extract the xml files and store the data in to data base table, program name is "zprogram_application".
When run the se38 it's working fine and save the data in database.
2. When i click "SUBMIT" button the web dynpro application automatically run the Report program "zprogram_application" and save the data into data base table. This is my requirement please give me suggestions.
3. I want run the report program in web dynpro application.
Thank you
V.VENKATESH

From within the WDA Event handler you can call the program using SUBMIT ... AND RETURN. You might have to be careful with what the program does. It must run as though it is in the background. There is no connection to the client machine - so no SAPGUI calls. You might also consider the addition VIA JOB job NUMBER n... to the SUBMIT command. That will allow you to start the submitted program as a background job. Your WDA can then continue processing as the submitted job runs in parallel.

Calling ABAP Code From BSP

Hello all,
I dont have much idea of BSP ans would like to have some inputs from you all.
I would like to know that can I call ABAP transaction from BSP page ?
I have got a set of column entries just as an ALV column on my BSP page and I would like to provide hotspot or double click functionality so that for each of the entries in the table , the BSP page navigates to ABAP tcode and back to BSP page.Is this functionality possible?
any help would highly be appreciated.
Regards
Amruta

Hi Amruta ,
You can't call an R/3 transaction directly from BSP.
But you can achieve all the functionalities it does .
for ex ..if an r/3 transaction is a report , u hav to code in BSP editor .u can call function modules from BSP .
But one thing u hav to concern is ,,in BSP Apllication logic is seperatd from Business logic .
U hav to move all your results into an itab / params and display that inside HTML tables .
Start ur journey from here .......
