SQL Query how to to get this Matrix report.

Question

Hi All,
My tables are
Petty_cash_voucher P :- voucher_date,terminal_id,currency_code,account_code, amount
Terminal_master T :-
terminal_id,terminal_station_code
Ledger_codes L :- account_code,account_description,accound_main_head_code
Account_main_heads :-
Account_main_head_code, Main_head_description
im looking for a MATRIX WITH GROUP REPORT should look like this
1st group : CURRENCY
2nd Group : Main_head_description
Row field is : account_description
Column field is : Terminal_town_code
Matrix CELL is : total_amount.
here i should see all my terminal_towns though the transactuons existed or not for that day. letssay there are 22 terminals, but today i have 2 terminals only transactions, but i need to see 22 as columns with NULL values. and for ledgers, main_heads what ever existed only. Ex: i have 100 ledgers with 20 Main heds, but there is 2 only transactions happend, i should see 2 group by main_head with 2 terminsla having values remiaing termils with null values.
i wrote the query like this , but it is not giving all terminal codes , giving only values existed.
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 (+) > = '16-jun-05'
AND
P.voucher_date (+) < = '16-jun-05'
GROUP BY
P.currency_code,
T.terminal_town_code,
P.account_code,
L.account_description,
SH.account_main_head_description.
Thanks in advance.
