In Oracle Fusion Cloud Procurement, IDR and OCR technologies are used to capture and extract data from invoices, automating the data entry process. OCR converts scanned invoice images into machine-readable text, while IDR intelligently interprets and extracts relevant fields (e.g., invoice number, amount). This reduces manual effort and errors. Option A (automated routing) is a downstream process, not the primary function of IDR/OCR. Option B (validation) is a secondary benefit, not the core purpose. Option D (supplier registration) is unrelated to invoice processing. This automation streamlines procurement workflows.
