B) The process involves performing a three-way-match of the PO, receiving report, and the Vendor Invoice. Before setting up an account payable the clerk will verify the items invoiced were ordered (PO), received in good condition (receiving report), and that the invoice charges are correct. To do this the clerk needs “Read” access to the PO and receiving report tables and “Read” and “Insert” access to the Vendor Invoice table. Once the three-way-match is complete, the clerk transcribes the details from the supplier’s hard copy invoice to the Vendor Invoice table and assigns a due date. This establishes the liability. The unpaid invoices at any point in time constitute the accounts payable.
The AP clerk normally would not have “modify” or “delete” access to the Vendor Invoice table. Editing and deleting existing records in a table should be a supervisor function.
Also, the clerk should not have insert, modify, or delete access to the PO and receiving report tables. Such access would allow the AP clerk to enter fraudulent PO and receiving report records. The clerk’s legitimate “insert” privileges would then allow him to create a fraudulent supplier’s invoice (on behalf of himself or a conspirator) and set up a false liability, which would later be paid.
