Fix IAM billing permissions.
Update your access permissions for AWS Billing, Cost Management, and Account services The following IAM actions for AWS Billing, Cost Management, and Account consoles have reached the end of standard support. These actions are replaced with fine-grained IAM actions: aws-portal:ViewBilling, aws-portal:ModifyBilling, aws-portal:ViewAccount, aws-portal:ModifyAccount, aws-portal:ViewPaymentMethods, aws-portal:ModifyPaymentMethods, aws-portal:ViewUsage, purchase-orders:ViewPurchaseOrders, and purchase-orders:ModifyPurchaseOrders. To ensure you don’t lose access to AWS Billing, Cost Management, and Account console based products, update your existing IAM policies to include the new IAM actions. Examples of features impacted include AWS Cost Explorer, AWS Budgets, Billing console, and more. You can also use the Bulk Policy Migrator to mass update polices from your Payer account (if using AWS Organizations) or use the old to granular action mapping guide to confirm the granular IAM actions which need to be added.
