AR - Customer Statement - differences when compared with the Aging report

Question

I am running the customer statement (the Print Statement program) 'as of date' say 11-Jun-09, and found that the 'Total Amount Due' for a customer is not agreeing back to the balance displayed on the Aging Screen (Navigation: Collections -> Customer Accounts [Aging butto]) for the customer.
The 'Total Amount Due' on the statement is greater than the balance on the aging report/screen.
It appears that the statement is selecting more receivables transactions (invoices, credit note, payments etc...) than the aging report is looking at. Also the aging buckets on the statement does not tie back to that on the aging screen /report for example the '4 Bucket Aging Report'.
My questions are:
1, Is it possible for the 'Total Amout Due' on the statement to differ from the balance on the aging report/screen?
2, What factors or reasons might cause the above senario to occur?
3, How can one start to investigate this in order to account for such differences?
Ideally what I would like to do is run a sql script that will show what is being selected for the statement 'as of' a particular date for a customer, and another sql that will show the same customer account balance and aging buckets at the same 'as of' date.
And perhaps another sql that would show the same customer open receivable transactions.
Thanks.

Hello.
This query will show you the customer open receivable transactions:
select c.customer_name,
decode(ps.class, 'PMT', 'Payment', 'INV', 'Invoice', 'DM', 'Debit Memo', 'CM', 'Credit Memo') Type,
ps.trx_number,
ps.trx_date "Inv Date",
ps.due_date "Due Date",
ps.acctd_amount_due_remaining "Amount Remaining"
from ar_payment_schedules_all ps,
ra_customers c
where c.customer_id = ps.customer_id
and ps.status = 'OP'
and ps.org_id = &orgID
and c.customer_number = &CustNumber
