Answer 1

Do you just need the check no attached to an invoice, please confirm ? In this case you need not refer to any of the GL tables ?
select check_number, p.invoice_id, p.payment_num, i.invoice_num, i.gl_date, i.invoice_amount
from ap_invoice_payments_all p,
ap_checks_all c,
ap_invoices_all i
where p.check_id = c.check_id
and p.invoice_id = i.invoice_id
and i.invoice_num = '90283-070108';
