Overview and register
Overview counts active suppliers and groups them by criticality tier. It also shows service review compliance, NDA expiry, and contract renewal. Those figures use active suppliers, not the whole historical list.
The register is where you find and open a supplier, including ones that are not active. Open a row for the full record: details, contacts, reviews, contracts, NDAs, other documents, and notes.
