You can use a left join and window functions:

select la.*
from (select la.*,
             min(case when fl.actual_user is not null then la.start_time end) over (partition by la.ticket_id) as actual_user_start_time
      from log_audit la left join
           final_log fl
           on fl.actual_user = t.user
     ) la
where start_time <= actual_user_start_time;

This is giving only one record. First record

@kalyan4uonly . . . I fixed the answer. The case used the wrong table for identifying which date.
