hi,
yes i think it's possible.
create a parameter with Import for your method say p_lt_reclist with multiline,
use the SWC_SET_TABLE CONTAINER 'p_lt_reclist' lt_reclist.
Bind p_lt_reclist with LT_RECTLIST (task container) and later to get it to your WF bind the task container to your WF container.
but make sure the element in the task container must be import and export enable.
Hope this can help you.
Regards.
