Data Flow is not working in Workflow

Question

Hello!
I want to start my workflow with 'SAPI_WAPI_CREATE_EVENT'.
But the workflow is not starting because it has error in the data flow of its task. Goal of the workflow is that the event send an email to the employee.
what should i do in the data flow? what have I put in the data flow?

Answer 1

I created an ABAP-Class with the event 'create_wf' and the method 'create_workflow' .
This class includes the interfaces bi_object, bi_persistent and if_workflow.
My method 'create_workflow' call the FM 'SAP_WAPI_CREATE_EVENT'. But what are the exporting parameter 'object_type' and object_key' and 'event'? Is 'event' my own event 'create_wf'? And where I define the event? (My report calling the method 'create_workflow'. Is this the definition?)
In my workflow I have the task and I don't know which objects or parameters to put in in the data flow? In the task (flag 'basic data') I have the object category APAB class with the object type 'zsieb_startwf' (name of my class) and the method i explaind before 'create_wf' (which is my event in the class)'. in the flag event trigger I put the same data again.
Did I forget anything?
Where do I integrate my workflow in my class? Or is this unnecessary?
Hope, you understand now my problem better.
Hi Anna,
I think you may be confusing 'events' as they relate to Workflow and 'events' as they exist in classes.
There is a table which contains business object related events, SWETYPV.  This provides the linkage between your business object (such as Invoice, BUS2081, or Purchase Order, BUS2012) and Event (Created, Changed, etc) and your workflow.
You need to know what object type and what event (in the workflow context) are required before you can proceed.
So if you are trying to start a workflow from SAP_WAPI_CREATE_EVENT, your import parameters might be:
  call function 'SAP_WAPI_CREATE_EVENT'
    exporting
      object_type             = 'BUS2081'
      object_key              = yourdocumentkey
      event                       = 'CREATED'
      commit_work             = 'X'
      event_language          = sy-langu
    importing
      return_code             = lv_retcode
      event_id                = lv_eventid.
Then, in transaction SWETYPV, you would have an entry linking the Object/Event pair to the 'receiver' - the Workflow Template, and use a Receiver Function Module such as SWW_WI_CREATE_VIA_EVENT_IBF to actually raise the event.
