To ensure the availability and quality of Business Central services, there are limits on certain operations.
See Microsoft's article Operational limits for Business Central online on the limits and, in some cases, the strategy behind them.
Managing environments
The Environments tab of the Business Central Administration Center provides you with an overview of the Business Central production and sandbox environments for the tenant, and where you can manage updates for each environment.
For more information on how to manage environments, see Microsoft's Managing Production and Sandbox Environments in the Admin Center.
Managing apps
An LS Central SaaS environment is built as a collection of apps. These apps include Microsoft apps and third-party apps, for example, apps from AppSource.
The apps work together to provide customers with a broad set of features to address their various business, market, and industry needs.
For more information see Microsoft's Managing Apps.
Managing capacity
To help customers manage and plan their storage costs regularly, the Business Central Administration Center includes the Capacity page.
The Capacity page provides an overview of the entire database and file storage usage, with details about the storage used by every environment. The page also displays the currently used and the maximum allowed number of production and sandbox environments available for the customer.
For more information see Microsoft's Managing Capacity.
