QuickSight now provides standardized user level cost and usage data

Amazon QuickSight administrators can now access user level cost and usage data for all user types in AWS Billing Cost and Usage Reports in a standardized format. This common format across reader, authors, and admin user types will allow QuickSight customers to create standardized cost breakdowns of their deployments, and enable cost charge back to internal teams and stakeholders. This change is applicable in all regions where Amazon QuickSight is available.
