Hi Beskau,
No the parameters need not be of the same name. You have to map trigger method parameters with Event Register_Fact parameters. You have write code in Trigger method for the mapping.
METHOD trigger.
DATA: lv_objtype TYPE sibftypeid,
lv_event TYPE sibfevent,
lv_objkey TYPE sibfinstid,
lr_event_parameters TYPE REF TO if_swf_ifs_parameter_container.

lv_event = 'REGISTER_FACT'. " Event Name.
