TheSupplier Portal (A)in Oracle Fusion Cloud Procurement allows suppliers to manage invoices and purchase orders (POs) by providing a self-service platform. Suppliers can view POs (e.g., 200 units due Friday), submit invoices, and track statuses in real time, reducing manual communication. Option B (Contract Fulfillment Automation) generates POs from contracts, not supplier management. Option C (IDR) extracts invoice data, not a supplier tool. Option D (Receipt Accounting) records receipts, not supplier interactions. For example, a supplier might invoice $2,000 for a PO directly in the portal, speeding up payment cycles and improving transparency.
