Attempting to report using multiple subqueries and filtering on result set

Question

I have an Oracle view which shows historic logs of changed data, effectively an audit view. The view is over two tables, a header and a detail table. I guess for the purpose of the question that is not too relevant but the structure of the view is. This is the view:
SQL> desc ifsinfo.history_log_join
Name Null? Type
*LOG_ID                                    NOT NULL VARCHAR2(10)
*MODULE                                    NOT NULL VARCHAR2(6)
*LU_NAME                                   NOT NULL VARCHAR2(30)
*TABLE_NAME                                NOT NULL VARCHAR2(30)
*TIME_STAMP                                NOT NULL DATE
*USERNAME                                  NOT NULL VARCHAR2(30)
*KEYS                                      NOT NULL VARCHAR2(600)
*HISTORY_TYPE                                       VARCHAR2(200)
*HISTORY_TYPE_DB                           NOT NULL VARCHAR2(20)
COLUMN_NAME NOT NULL VARCHAR2(30)
OLD_VALUE VARCHAR2(2000)
NEW_VALUE VARCHAR2(2000)
I have indicated header information with *.
The detail shows every column that was changed for a table (in header) and the old and new values, quite straight forward.
The table I am interested in the audit of is:
SQL> desc customer_order_reservation_tab
Name Null? Type
* ORDER_NO NOT NULL VARCHAR2(12)
* LINE_NO NOT NULL VARCHAR2(4)
* REL_NO NOT NULL VARCHAR2(4)
* LINE_ITEM_NO NOT NULL NUMBER
* CONTRACT NOT NULL VARCHAR2(5)
* PART_NO NOT NULL VARCHAR2(25)
CONFIGURATION_ID NOT NULL VARCHAR2(50)
* LOCATION_NO NOT NULL VARCHAR2(35)
* LOT_BATCH_NO NOT NULL VARCHAR2(20)
* SERIAL_NO NOT NULL VARCHAR2(15)
WAIV_DEV_REJ_NO NOT NULL VARCHAR2(15)
ENG_CHG_LEVEL NOT NULL VARCHAR2(2)
* PICK_LIST_NO NOT NULL VARCHAR2(15)
PALLET_ID NOT NULL VARCHAR2(10)
* LAST_ACTIVITY_DATE DATE
SOURCE VARCHAR2(25)
QTY_ASSIGNED NOT NULL NUMBER
QTY_PICKED NOT NULL NUMBER
QTY_SHIPPED NOT NULL NUMBER
DELIV_NO NUMBER
ROWVERSION DATE
I have indicated columns that I am interested in (either as a key field or as changed data) by *
Okay - so that's the background, what am I attempting to report.
I want to return a single row per log id (for certain criteria) which shows:
Log_Id
History_Type
Time_Stamp
Username
Order_No
Pick_List_No
Rel_No
Line_No
Part_No
Loc_No
Lot_Batch_No
Serial_No
The SQL I have currently is:
select grp.*
from
(select h1.log_id, h1.history_type, time_stamp, username,
(select h2.old_value||h2.new_value from ifsinfo.history_log_join h2 where h1.log_id=h2.log_id and h2.column_name ='ORDER_NO') Order_No,
(select h2.old_value||h2.new_value from ifsinfo.history_log_join h2 where h1.log_id=h2.log_id and h2.column_name ='PICK_LIST_NO') Pick_List_No,
(select h2.old_value||h2.new_value from ifsinfo.history_log_join h2 where h1.log_id=h2.log_id and h2.column_name ='REL_NO') Rel_No,
(select h2.old_value||h2.new_value from ifsinfo.history_log_join h2 where h1.log_id=h2.log_id and h2.column_name ='LINE_NO') Line_No,
(select h2.old_value||h2.new_value from ifsinfo.history_log_join h2 where h1.log_id=h2.log_id and h2.column_name ='PART_NO') Part_No,
(select h2.old_value||h2.new_value from ifsinfo.history_log_join h2 where h1.log_id=h2.log_id and h2.column_name ='LOCATION_NO') Loc_No,
(select h2.old_value||h2.new_value from ifsinfo.history_log_join h2 where h1.log_id=h2.log_id and h2.column_name ='LOT_BATCH_NO') Lot_Batch_No,
(select h2.old_value||h2.new_value from ifsinfo.history_log_join h2 where h1.log_id=h2.log_id and h2.column_name ='SERIAL_NO') Serial_No
from ifsinfo.history_log_join h1
where
table_name = 'CUSTOMER_ORDER_RESERVATION_TAB'
and
keys like upper('CONFIGURATION_ID=*^CONTRACT=&company%')
and
history_type in ('Delete','Insert')
and
column_name ='PICK_LIST_NO'
and
username != 'IFSAPP'
and
h1.old_value || h1.new_value != '*'
and
trunc(h1.time_stamp) > trunc(sysdate-1-&days_ago)
order by 5, 6, 8, 7,9,10,2, 1) grp
This is OK but..
I only want to include rows where the same picklist / rel_no / line_no / part_no combination exist more than once (because there is always an insert and delete for the analysis I am doing).
AND
where for that combination, the lot_batch_no OR serial_no are different.
Effectively the system does an insert / delete rather than an update, so that is why.
Thanks
