The document describes two key business cycles - procure to pay (P2P) and order to cash (O2C).
The P2P cycle involves requisition, purchase order, goods receipt, invoice creation, payment, and general ledger transfer. The O2C cycle involves order creation, order booking, pick/ship confirmation, invoice generation via a workflow process, and receipt entry against invoices.
For each major step, the document lists the backend database tables impacted, such as PO_HEADERS_ALL, RCV_SHIPMENT_HEADERS, AP_INVOICES_ALL, and OE_ORDER_HEADERS_ALL. It also provides example SQL queries to retrieve records from these tables.
