data(cnt) = cl_swf_cnt_factory=>create_event_container( 
                            im_objcateg = 'CL' 
                            im_objtype  = class 
                            im_event    = event ). "START
Data(evt) = cl_swf_evt_event=>get_instance( 
                im_objcateg        = 'CL'
                im_objtype         = class

Here are the images posted by the OP, to avoid the pain of clicking multiple times to see them.

That's just the same image as create1.jpg already shown by the OP. NB: if you don't want to share an image, you may delete it in your question (but it's too late if someone has posted an answer...)

Do you want to trigger it by event (see Matthew answer), by Message Control (CA-GTF-BS), by BOPF, ..., or directly by the ID of the workflow definition? (the latter choice is the worst one)

vikash.pathak Why triggering the task only? (you told us that this task is one step among the three of your workflow definition)

Then how to trigger whole workflow that all steps could trigger through ABAP Report

Hi ,

If you do not have any events assigned to the workflow definition then use SAP_WAPI_START_WORKFLOW function module to start worklfow from a report. Pass the Workflow ID to this function module and pass abap_true to commit work parameter of the function module. It will start the workflow.

Hello Pavan,

Thanks for your suggestion , but this FM doesnot have Workflow id option rather it has TASK,

this function i am not sure will fullfill my requirement or not,

as i stated i have 3 steps in workflow , every steps has export container parameter which i have to show as abap report output too.

Thanks

Hi Vikash,

You are correct the task id is the parameter which you are suppose to pass workflow ID for instance the sample code is below

CALL FUNCTION 'SAP_WAPI_START_WORKFLOW'
  EXPORTING
    task            = 'WS999999XX'
    language        = sy-langu
    do_commit       = 'X'
  IMPORTING
    return_code     = lv_re_code " Sy-subrc value or success  = 0
    workitem_id     = lv_wiid " top workitem id
  TABLES
    input_container = lt_cont. " If you want to pass some values from report to Workflow container

Regarding your requirement, once you start the workflow the export and import from workflow to task container is done within workflow binding definitions.
