Query help to get Matrix report

Question

Hi All,
I have posted this query in Reports forum, didnt get replies, so im posting at Database general may be it could be the query problem.
Account Main Heads
Account_main_head_code, Main_head_description
01 ADMINSTRATIVE
02 OPERATIONAL
Ledger_codes account_code,account_description,accound_main_head_code
01 SALARIES 01
02 PHONES 01
03 FUEL 02
Terminal_master
Terminal_id,terminal_station_code
1 HYD
2 VJA
3 NY
4 WDC
Petty_cash_voucher voucher_date,terminal_id,currency_code,account_code,amount
30-jun-05 1 GBP 01 100
30-jun-05 2 GBP 01 200
30-jun-05 3 GBP 02 300
30-jun-05 4 GBP 03 250
Im looking for the MATRIX layout as follows :
GBP (first group)
ADMINISTRATIVE (secind group)
.................HYD.....VJA....NY ....WDC
Salaries.........100.....200.....0......0
Phones............0.......0.....300.....0
OPERATIONAL
.................HYD.....VJA....NY....WDC
Fuel..............0.......0.....0.....250
My query is like this
SELECT
P.currency_code,
T.terminal_town_code,
P.account_code,
L.account_description,
MH.account_main_head_description,
SUM(P.amount) total_amount
FROM
terminal_master T,
petty_cash_voucher_master P,
ledger_accounts L,
account_main_heads MH
WHERE
T.terminal_id = P.account_to_terminal (+)
AND
L.account_code (+) = P.account_code
AND
MH.account_main_head_code (+) = L.account_main_head_code
AND
P.voucher_date (+) > = '30-jun-05'
AND
P.voucher_date (+) < = '30-jun-05'
GROUP BY
P.currency_code,
T.terminal_town_code,
P.account_code,
L.account_description,
SH.account_main_head_description.
My current output is like this.
right now with the the existing query im getting like this
GBP (first group)
ADMINISTRATIVE (second group)
.................HYD.....VJA....NY ....WDC
Salaries.........100.....200.....0......0
Phones............0.......0.....300.....0
OPERATIONAL
.................WDC
Fuel.............250
While i need all the terminal at OPERATIONAL expenses also.

you'll need an auxiliary calender table :
