AWS is retiring IAM actions for AWS Billing, Cost Management, and Account consoles under aws-portal service prefix, purchase-orders:ViewPurchaseOrders, and purchase-orders:ModifyPurchaseOrders on July 6, 2023. Today, we are launching bulk migration scripts to allow customers to update policies containing the above old actions on the retirement path to include new fine-grained actions securely and quickly. Customers can execute these scripts from their management accounts and update all affected policies in their Organization to include new actions, while maintaining their current access to AWS Billing, Cost Management, and Account consoles.
