SAP Workflow RFC WebDynPro

Hi,
I have to set the values of input_container of sap_wapi_start_workflow and then execute the RFC. This I have to do it through web dynpro. Please help me.
Regards,
Srinivas

Hi,
Thank you for your reply.....
as you said,
IPrivate<view_name>.IInput_ContainerElement ele = wdContext.createInput_ContainerElement();
this is not available, so I changed it to
IPublicCO_ESSCertReq.IInput_ContainerElement ele = wdContext.createInput_ContainerElement(new Swr_Cont());
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().currentInput_ContainerElement().setElement("PersonnelNumber");
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().currentInput_ContainerElement().setValue(EmpId);
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().addElement(ele);
               IPublicCO_ESSCertReq.IInput_ContainerElement ele1 = wdContext.createInput_ContainerElement(new Swr_Cont());
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().currentInput_ContainerElement().setElement("EForm");
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().currentInput_ContainerElement().setValue(CertCode);
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().addElement(ele1);
               wdComponentAPI.getMessageManager().reportSuccess("6");
My complete Code is :
Sap_Wapi_Start_Workflow_Input input=new Sap_Wapi_Start_Workflow_Input();
               wdComponentAPI.getMessageManager().reportSuccess("1");
               input.addInput_Container(new Swr_Cont());
                              wdComponentAPI.getMessageManager().reportSuccess("2");
               wdContext.nodeSap_Wapi_Start_Workflow_Input().bind(input);
               wdComponentAPI.getMessageManager().reportSuccess("3");
               wdContext.nodeSap_Wapi_Start_Workflow_Input().currentSap_Wapi_Start_Workflow_InputElement().setTask("WS90600006");
               wdComponentAPI.getMessageManager().reportSuccess("4");
               IPublicCO_ESSCertReq.IInput_ContainerElement ele = wdContext.createInput_ContainerElement(new Swr_Cont());
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().currentInput_ContainerElement().setElement("PersonnelNumber");
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().currentInput_ContainerElement().setValue(EmpId);
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().addElement(ele);
               IPublicCO_ESSCertReq.IInput_ContainerElement ele1 = wdContext.createInput_ContainerElement(new Swr_Cont());
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().currentInput_ContainerElement().setElement("EForm");
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().currentInput_ContainerElement().setValue(CertCode);
               wdContext.nodeSap_Wapi_Start_Workflow_Input().nodeInput_Container().addElement(ele1);
               wdComponentAPI.getMessageManager().reportSuccess("6");
               wdContext.currentSap_Wapi_Start_Workflow_InputElement().modelObject().execute();
               wdComponentAPI.getMessageManager().reportSuccess("Executed successfully, Request has been forwarded to your RM");
but when I execute, I am getting the below error...

How to integrate SAP HR Workflows with Webdynpro ?

Hello All,
Could you please drop some hints for the below points please ?
How do we trigger SAP workflow from Webdynpro DC? Usually if its a RFC we import RFC through Model and trigger the RFC. Can that be done only through Adobe forms? If yes,how do we trigger work flow through Adobe Forms?
Many Thanks,
Dhanya

Hi, Dhanya
Of course via RFC! Usually these workflow related RFMs are called WAPI
(Workflow API).
Please refer to this thread.
Workflow and Trigger Event
And Adobe forms is not relevant to SAP workflow at all. Usually, Adobe forms
+ workflow scenarios are achieved via the above workflow APIs.

Integration of SAP Business Workflow and Webdynpro

Hello colleague,
Could you pls. provide any pointers in configuring the following scenario:
There is a SAP workflow configured in R/3. When one of the steps of the workflow is executed I have to trigger a Web Dynpro (for ABAP) screen.
Say its an approval workflow and when the manager clicks on the workitem in the inbox a webdynpro screen will pop up indicating the requisite information. The manager can approve or reject the based on information on the screen. The user action will be taken and the workflow will proceed based on that.
Any pointers in this will be of great help.
Regards,
Gajendra.

I would like to know as well about this, did you get an answer?
Thanks for any pointers.

Calling a java webdynpro component inside a SAP Workflow

Hi Experts ,
Is it possible to call a java webdynpro component inside a SAP Workflow from the task .
If yes please let me the procedures .
Regards
Sarmistha

Someone has posted this, Take a look if it helps you:
"1. Activate your service in transaction SICF;
2. Activate the WS_HANDLER in SICF (probably you have to do more in SICF, SAP notes will be given to you in your browser when you want to call the service);
3. Make the correct settings in WF_HANDCUST;
4. Do ofcourse SWU3 including webserver activities;
5. Define how you want to call the service via WF_EXTSRV including parameters;
6. Generate a task from your defined service in WF_EXTSRV;
7. Incorporate this task in your workflow definition;
8. Test your workflow. Here you probably get some errror messages that the service cannot be called by for instance inactive ICF services. Activate the correct paths in transaction SICF."

How to route the information to approver with out involving sap workflows.

Hi Developers,
i have a doubt regarding how the requester filled form information will be send to approver with out involving SAP workflows in the portal.
Normally i know the procedure where users fills the form with the approver details, the filled information is routed to approver UWL by trigerring a function module thru webdynpro.
But i need to know is there any procedure to route the information without involving any backends.
Thanks in Advance.

Michele is correct - sneep will help you get the serial from the running domain on the M3000 ,
and it is a good idea to install STB on your machines.
If that isn't possible for you, then sneep can be downloaded directly from [http://www.sun.com/sneep]
I believe that on this platform, sneep gets the serial from the output of prtconf.
There is a minor correction to be made :
After installed SNEEP use "man sneep" for all technical details.The sneep man page is not linked into the shared man pages, so you need to use
man -M /opt/SUNWsneep/man sneep
with out going to OK prompt (Banner)It is worth noting that the serial shown in the OBP banner is not the product serial
that you will find on the physical serial tag.
The banner "serial" is the decimal equivalent of the host ID, which you normally get in hexadecimal from the "hostid" command.

Calling SAP scripts from WEBDYNPRO

Hi
We need to call SAP scripts from WebDynpro application. As per my understanding we need to do following steps
Create a new RFC function module and create sap script output in PDF format.For this
    - use OPEN_FORM , by assigning TDGETOTF='X' in the Options(Structure
      ITCPO).
    - call function module CLOSE_FORM with option OTFDATA
    - convert OTF data to PDF by using function module CONVERT_OTF_2_PDF
Now I would like to know how to display the PDF string from WebDynpro.
Please help....
Regards
Sujith

Hi,
You can call by creating external window method.
create LINK to URL or LINK TO ACTION according to requirement, for this. write code in onaction of that.
data: iv_url type string value 'http://<server>:<port>/sap/bc/gui/sap/its/webgui?~transaction=*se38 RS38M-PROGRAMM=rsparam;DYNP_OKCODE=SHOP'.
data: api_component type ref to if_wd_component,
          window_manager type ref to if_wd_window_manager,
          window type ref to if_wd_window.
api_component = wd_comp_controller->wd_get_api( ).
window_manager = api_component->get_window_manager( ).
window = window_manager->create_external_window(
                 url = iv_url
                 modal = abap_false ).
window->open( ).

Binding Structure/Internal Table to Workflow from Webdynpro

Hi Gurus,
I have to trigger workflow from WEBDYNPRO application. For now I have two ways they are:
1. Triggering WFLow using SAP_WAPI_START_WORKFLOW (Successfull):
How could I bind Structure/Internal Table (DDIC referred structure) to workflow directly. Presently I am mapping indvidual fields which makes my code complex using FM SAP_WAPI_START_WORKFLOW.
2. Triggering WFLow using SAP_WAPI_CREATE_EVENT (Bindind issues):
Also When I try to submit using BOR event with SAP_WAPI_CREATE_EVENT workflow triggers successfully But I cannot able to bind the values. So are there any specific configuration need to be made.( like making task as General while triggering workflow using SAP_WAPI_START_WORKFLOW).

Hi
Please make use of the below code
INCLUDE cntn01_swc.
DATA lt_kna1    TYPE TABLE OF kna1.
DATA lt_cont    TYPE TABLE OF swcont.
DATA lv_wiid    TYPE          sww_wiid.
swc0_create_container lt_cont.
SELECT * FROM kna1 INTO TABLE lt_kna1 UP TO 10 ROWS.
swc0_set_table lt_cont 'CUST' lt_kna1.
CALL FUNCTION 'SWW_WI_START'
EXPORTING
    creator                      = sy-uname
    task                         = 'WSXXXXXXXX'
    do_commit                    = 'X'
IMPORTING
    wi_id                        = lv_wiid
TABLES
    wi_container                 = lt_cont
EXCEPTIONS
    id_not_created               = 1
    read_failed                  = 2
    immediate_start_not_possible = 3
    execution_failed             = 4
    invalid_status               = 5
    OTHERS                       = 6.
IF sy-subrc <> 0.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
          WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
The other way to do is you can also make use of OO ABAP classes to trigger the workflow. If you want to create a rfc function module then create a wrapper function module .
SAP_WAPI_START_WORKFLOW cannot transfer structures or tables which are more thatn 255 characters. So the work around is either make use of OO container or SWCONT container.
The above code snippet should be included in the assistance class of the webdynpro application and you need to include the define the include cntn01_swc in the class local types under macros.
and then you create a method ....... and include the above code in that method.   excluding the include statement.

Kicking off workflow from webdynpro using events?

I have abap experience but no workflow. Any advice will be appreciated.
I have to kick off a workflow from webdynpro. I assume that I have to set up a business object (eg. ZOBJECT), create an event therein (eg. ZEVENT).
Then when webdynpro runs I use a rfc function module to trigger this event.
The questions I have are:
1. How do I set up the workflow to be triggered by this event?
2. Do I set up an event in Business object builder or in SM62?
3. How do I trigger an event in a function module. I have found SWE_EVENT_CREATE but don't want to create an event just want to trigger the event and in turn set off the workflow?
Thank you,
Warren.

try this below parameters are passed or not
CALL FUNCTION 'SAP_WAPI_CREATE_EVENT'
           EXPORTING
             object_type    = 'BUS2105'
             object_key     = lv_objkey
             event          = 'CREATED'
             commit_work    = 'X'
             event_language = sy-langu
             language       = sy-langu
             user           = sy-uname.

CAF Java-Based COs with SAP Workflows as Runtime Environment?

Hi Folks,
we have a big CAF project hitting us at the moment.
Due to the heavy load we expect we do want to have the traditional SAP workflows as the runtime environment for our GPs.
As far as I know we can transfer WFs designed with CAF GP to the R/3 WF system, right?
My question is know: Can we still develop in Java our CAF objects and use them as we would do that in a portal based GP??
If this should be possible - is this creating an overhead killing the benefit we gain by shifting from portal to the ABAP stack?
Any hint is appreciated!
helge

Hi Helge,
Technically, there is no transfer from Guided Procedures to the R/3 Workflow since the process definitions still stay in the GP Design Time. The business logic still takes place on the Java Stack. Only the low-level workflow operations are delegated to the r/3 Workflow.
That's a difficult dilemma that you are facing right now. As far as I know, the configuration to get Guided Procedures running against the Business Workflow (R/3 Workflow) is quite complex and time consuming. Main pain points are callbacks registrations for background steps, user mapping and endpoints configuration. These are the main tasks. But to reach the right configuration, you will have to be tricky and patient.
Furthermore, there will be an overhead due the RFC Roundtrips between the Java Stack and the ABAP Stack.
Hope this helps you.
Best regards,
David

Trigger MDM Workflow in Webdynpro

Hello,
I want to execute a MDM Workflow from Webdynpro using Java API's. I have the WorkflowId,session Id and the RecordId in the Webdynpro. Can somebody please send the code for the same.?
Any help would be highly appreciated.
Thanks.

Hi,
Check the pdf at the below link.
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/600333e0-9bf7-2c10-1f99-bf5dcf661949?quicklink=index&overridelayout=true
Try using this code for calling MDM workflow:
RetrieveWorkflowTasksCommand task_command = new RetrieveWorkflowTasksCommand(connections);
task_command.setSession(sessionId);
task_command.setTableId(new TableId(1));
try {
task_command.execute();
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
//Retrieving the tasks after execting the command
WorkflowTask [] task = task_command.getWorkflowTasks();
for(int i = 0 ; i < task.length ; i++)
WorkflowJob job = task.getJob();
job_id= job.getId();
System.out.println(job_id.getIdValue());//This is will give the Job ID of all the workflows in MDM.
Thanks

How to work with a workflow in Webdynpro

Hi Team,
       I am new to webdynpro ABAP, i have a scenario
I have a work flow id with me, i want to start this workflow from a webdynpro application,
1. wedynpro application contains a list of inputs and user1 inputs this data that i have stored node, So node contains full data.
2. Now i have a workflow id, i want to pass this node data to this workflow on a button click
    I have the button action, what code is required to pass this?
         (I sow few FMs in fourms but i dont know how exactly i can use it)
3. When the approver gets the workitem, he should be able to approve,reject or send backToAuthor option he will get
     how to read this data back to approver screen for the approver to take correct action ?
Please help me with some code sample, i sow few things but i am not sure about the parameters which required for this.
Thanks,
   PP

Hi,
1) In order to trigger the workflow from webdynpro and pass the list of inputs and your workitem id , i will suggest you to go for    a   business object.
2) If you have a business object than you can just trigger the workflow through the event (provided your workflow should be an event trigger workflow). As well as you can pass your parameters through it.
3) In order to trigger the workflow through your business object event u can use the following function module.
in the below code:-
it_container- contains the parameter u want to pass like workitem id in your case.
ZPOC_LEAVE- is my business object.
OPTIONAL- is my event which will trigger the workflow.
ty_object_key:- structure type of key fields of business object.
Note:-you have to define these values as per your business object.
* Trigger the event ZPOC_leave-CREATE to start the workflow
DATA: it_container TYPE TABLE OF swr_cont,
             is_container LIKE LINE OF it_container.
DATA: g_return_code TYPE sy-subrc,
             glf_event_id TYPE swr_struct-event_id.
DATA : ls_objkey TYPE ty_objkey.
DATA : ls_objtype TYPE swr_struct-object_typ VALUE 'ZPOC_LEAVE'.
DATA : ls_objectkey TYPE swr_struct-object_key.
DATA : ls_event TYPE swr_struct-event VALUE 'OPTIONAL'.
CALL FUNCTION 'SAP_WAPI_CREATE_EVENT'
    EXPORTING
      object_type             = ls_objtype
      object_key              = ls_objectkey
      event                   = ls_event
      commit_work             = 'X'
      event_language          = sy-langu
      language                = sy-langu
      user                    = sy-uname
*   IFS_XML_CONTAINER       =
   IMPORTING
     return_code             = g_return_code
     event_id                = glf_event_id
   TABLES
     input_container         = it_container
*   MESSAGE_LINES           =
*   MESSAGE_STRUCT          =
4) You also need to define the parameter(workitem id in your case) under the parameter option of your event in your business object. (you can use the transaction SWO1 for business objects).
5) Now in swdd transaction in the basic data u can mention your start event.
This should be enough to trigger your workflow and pass your workitem id to it.
Thanks and regards,
Mayank Gupta
