WHY IT NEEDS A POLICY

Why ariba_contract_compliance_update_lineitems needs a policy

This tool performs a reversible modification (PATCH) of contract line items, making it a Write operation rather than Destructive. However, severity is high because contracts and their line items are critical business documents in procurement—unauthorized modifications could alter supplier agreements, pricing, quantities, or terms, leading to significant financial or operational consequences.

From the tool's definition PATCH /contractRequests/{contractRequestId}/lineitems - this is a PATCH operation that modifies line items in contract requests, which are core procurement documents in SAP Ariba.
