Abstract
An accounts payable system in which invoices submitted by electronic data interchange (EDI) are audited for duplicate invoices prior to them being entered into the production database, or environment. Pre-processor logic audits, identifies and returns electronically duplicate transmissions. At this pre-processor level, all inbound invoices are sorted in credit/debit sequence. Invoices are posted (committed to the production accounts payable environment; that is, to the accounts payable data base) one at a time so purchase order history is current for each evaluation. Inbound invoices are sorted by credit/debit. Only debits are audited.
