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';
