Set the workflow about PPR process as completed status with a report.

Question

Hi Gurus,
I need to complete a workflow and all regarding task from UWL.
To do this, I implemented 2 functions module: the first to execute the dialog step and the second to set the dialog step as completed status.
When I run the report the both function module doesn't work. Sy-subrc  return me different result as 0.
If I execute the SWIA T-code, I see all the task and there I execute the "dialog step" WORK ITEM to set it from ready status to started status and after I use "complete manualy" for the same task then the workflow created a new "dialog step" WORK ITEM I do the same with it and the workflow is completed.
So I would like to do the same in a report with SAP_WAPI_SET_WORKITEM_STATUS and SAP_WAPI_DECISION_COMPLETE functon module ... please see my code below:
loop at lit_wi_stat where wi_type = 'W' and wi_stat = 'READY'.
*to set dialog step WORK ITEM as started status.
      call function 'SAP_WAPI_SET_WORKITEM_STATUS'
        exporting
          workitem_id          = lit_wi_stat-wi_id
          status               = 'STARTED'
          user                 = sy-uname
          language             = sy-langu
          do_commit            = 'X'
        importing
          new_status           = lit_wi_status
          return_code          = lv_subrc
      TABLES
        MESSAGE_LINES        =
        MESSAGE_STRUCT       =
*to set dialog step WORK ITEM as completed status
      call function 'SAP_WAPI_DECISION_COMPLETE'
        exporting
          workitem_id          = lit_wi_stat-wi_id
          language             = sy-langu
          user                 = sy-uname
          decision_key         = '0001'
          do_commit            = 'X'
      IMPORTING
        RETURN_CODE          =
        NEW_STATUS           =
      TABLES
        MESSAGE_LINES        =
        MESSAGE_STRUCT       =
    endloop.
But it doesn't work correctly.
Maybe you have a better idea to reproduce the complete process in a report.
Thanks in advance for your reply..
Best regards.

Hi Chandni
I would presume that you are calling some activity step to perform some operation ...when this fails, you are passing some flag to the workflow to send the email and the "planned" error!
It's pretty simple then:
1) Analyze the flag using a condition step
2) Use mail step to send the email
3) Call a custom method to raise a workflow exception - workflow will go in error.

BO Based Exception:

How you can define custom BO:

Or you can also trigger Class based Exceptions if you are using ABAP OO for workflow (custom functionality via Class using IF_WORKFLOW Interface). Just make sure you make your Custom Exception Class as a child of CX_BO_TEMPORARY or CX_BO_APPLICATION
