You can use Oracle XML Gateway to receive invoices from suppliers using XML messaging standards. Oracle supports the XML standard that was developed by the Open Applications Group (OAG). Oracle uses the OAG's Process Invoice DTD called 171_Process_Invoice_002.dtd (version 7.2.1). Suppliers need to generate XML invoices that comply with this standard to ensure that these invoices can be received through the Oracle XML Gateway and processed by Payables. Please refer to the OAG website www.openapplications.org for more information on OAG standards.
