Answer 1

Hi,
In order to trigger an event programmatically, we would use the function module SWE_EVENT_CREATE.
<b>BUS1001006 ( Standard Material )</b>
here is the sample code.
DATA: key LIKE sweinstcou-objkey.
key = '68." Material Number (hard-coded)
CALL FUNCTION 'SWE_EVENT_CREATE'
  EXPORTING
    objtype                       = 'BUS1001006'
    objkey                        = key
    event                         = 'CREATED'
  CREATOR                       = ' '
  TAKE_WORKITEM_REQUESTER       = ' '
  START_WITH_DELAY              = ' '
  START_RECFB_SYNCHRON          = ' '
  NO_COMMIT_FOR_QUEUE           = ' '
  DEBUG_FLAG                    = ' '
  NO_LOGGING                    = ' '
  IDENT                         =
IMPORTING
  EVENT_ID                      =
TABLES
  EVENT_CONTAINER               =
EXCEPTIONS
  OBJTYPE_NOT_FOUND             = 1
  OTHERS                        = 2
IF sy-subrc <> 0.
  MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
          WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ELSE.
  WRITE 'Event Triggered'.
ENDIF.
COMMIT WORK.
In order to test whether the event is getting triggered or not, we can make use of Event Trace. Switch on the event trace using the transaction SWELS. 
Press ‘Switch On”. 
Now execute the program developed earlier. Now switch-off the event trace using the same transaction SWELS. 
Now go to transaction SWEL. Here you can list out the events triggered in the particular period of time. Here is the event-trace list:
