In a function exit of a workflow task, you can copy the sample coding out of class CL_SWH_WORKITEM_EXIT_LOG to append a custom message
METHOD if_swf_ifs_workitem_exit~event_raised .
DATA: ls_msg TYPE swr_mstruc.
DATA: ls_por TYPE sibflporb.
DATA: l_cnt TYPE REF TO if_swf_ifs_parameter_container.
me->m_ctx = im_workitem_context.
IF im_event_name EQ swrco_event_after_creation.
ls_msg-msgid = 'SWH'.
ls_msg-msgty = 'S'.
ls_msg-msgno = '100'.
ls_msg-msgv1 = 'CL_SWH_WORKITM_EXIT_LOG'.
ls_msg-msgv2 = 'swrco_event_after_creation'.
l_cnt = m_ctx->get_wi_container( ).
TRY.
CALL METHOD l_cnt->get
EXPORTING
name = swrco_wi_leading_object
IMPORTING
value = ls_por.
CALL METHOD m_ctx->set_message_to_log
EXPORTING
im_message = ls_msg
im_object_por = ls_por.

But to add a message in general, only the workitem context is needed. If you got the context, just use method set_message_to_log.
* context type: im_workitem_context TYPE REF TO if_wapi_workitem_context
" text in im_function will be displayed in workitem log (max char30),
" message in im_message will give further information when clicking on the traffic light (max char 70).
im_workitem_context->set_message_to_log( im_function = |Forward: Mail { var }|
im_message = VALUE #( msgid = '00'
msgty = 'S'
msgno = '000'
msgv1 = |var 1|
msgv2 = |var 2| ) ).
* In some cases "COMMIT WORK" is needed.
You’ll find the log entry in workitem flog view:
