How to give Container Elements for FM EWW_WORKFLOW_START

Question

hi experts,
i am new to workflow,
i am using the FM EWW_WORKFLOW_START to start a workflow.
my issue is that i am using the std BO BUS2017
i am not getting the element name that i need to pass to the container.
When i see in SWDD it shows
Import Parameter BUS2017 in the list of workflow container elements. but when i pass the OBJKEY: materialDocument and matdocumentyear like
concatenate '5000000305'  '2009 ' into text1.
swc_set_element   t_cont  'BUS2017' text1 .
its not getting passed to the workflow.
but i added 2 new elements mblnr and year to the container and i pass it , it gets passed.
how can i know the exact Element name?
or where could i be wrong?
thanks and regards,
Gunj M.

Hello,
Here's some sample code of how to pass an object:
INCLUDE <CNTN01>.
data: lv_rc like sy-subrc.
data: lt_messages type standard table of SWR_MESSAG.
data:
begin of lv_object_instance,
  objtype type swo_objtyp,
  objkey  type swo_typeid,
end of lv_object_instance.
* Define the container
swc_container lt_wf_cont.
* Create the container
swc_create_container lt_wf_cont.
* Clear the container (not necessary here)
swc_clear_container lt_wf_cont.
lv_object_instance-objtype = 'FORMABSENC'.
lv_object_instance-objkey = '0000000088'.
lt_wf_cont-element = 'ABSENCEFORM'.
lt_wf_cont-value = lv_object_instance.
append lt_wf_cont.
CALL FUNCTION 'SAP_WAPI_START_WORKFLOW'
EXPORTING
   TASK                     = 'WS30000015'
*   LANGUAGE                 = SY-LANGU
   DO_COMMIT                = 'X'
*   USER                     = SY-UNAME
*   START_ASYNCHRONOUS       = ' '
*   DESIRED_START_DATE       =
*   DESIRED_START_TIME       =
*  IMPORTING
   RETURN_CODE              = lv_rc
*    WORKITEM_ID              = lv_wfid
*    NEW_STATUS               = lv_wistat
TABLES
   INPUT_CONTAINER          = lt_wf_cont
   MESSAGE_LINES            = lt_messages
*   MESSAGE_STRUCT           =
*   AGENTS                   =
