I suggest writting something like this.
select report_id, dm_ip, dm_mac, dm_user,
dm_os, report_time, sys_name,
sys_user, sys_user_domain, ss_key,
login_time, role_id, new_vlan_id
from repcopy as a
(select max(report_time) as rtime,
dm_user, dm_ip
from repcopy
group by dm_user, dm_ip
where ss_key != '') as materialized
where report_time = materialized.rtime
and materialized.dm_user = a.dm_user
and materialized.dm__ip = a_ip
and report_status = 0
and dm_user = 'u3';
