Because payments cannot be made in Oracle without the entry of a related invoice, the risk having these two processes alone would be limited to collusion with the supplier or other employees to enter goods NOT received. If Payment on Receipt (ERS) is used, additional controls need to be put in place including the setup of such at the Supplier Site level. If ERS/ Pay on Receipt will not be used, the Receipt AutoInvoice Program should be removed from all users so it cannot be used.
