Determining the last archive applied on Logical Standby

Question

Hi,
I am trying to determine the last log received and applied on my Logical Standby
SQL> select thread#, max(sequence#) "Last Standby Seq Received"
from v$archived_log val, v$database vdb
where val.resetlogs_change# = vdb.resetlogs_change#
group by thread# order by 1;
   THREAD# Last Standby Seq Received
         1                       14
SQL> select thread#, max(sequence#) "Last Standby Seq Applied"
from v$archived_log val, v$database vdb
where val.resetlogs_change# = vdb.resetlogs_change#
and applied='YES'
group by thread# order by 1;
Does not return anything
These statements work ok on a physical standby.
I know Sql Apply is enabled on my logical standby - my broker configuration is enabled and for the logical standby database, it is showing the Intended State as APPLY-ON with no Transport or Apply Lag on any of the databases
Q. How do I determine the last seq applied on my logical standby ?
thanks,
Jim

Hello;
I have this from my notes:
SELECT
  L.SEQUENCE#,
  L.FIRST_TIME,
  (CASE WHEN L.NEXT_CHANGE# < P.READ_SCN THEN 'YES'WHEN L.FIRST_CHANGE# < P.APPLIED_SCN THEN 'CURRENT' ELSE 'NO' END) APPLIED
FROM
  DBA_LOGSTDBY_LOG L, DBA_LOGSTDBY_PROGRESS P
ORDER BY SEQUENCE#;
