- You can't trigger Power Automate flows from calculated or rollup columns.
- Rollup columns are only recalculated every hour.
- Business rules can only access the columns on the form for its own table.
- Classic workflows can't access rows in 1-to-many relationships.
- Data that is changed by a business rule will not trigger an OnChange event that was created with JavaScript.
Platform limits
The platform doesn't provide an infinite amount of resources, and limits are imposed on the number of API calls that can be made.
API requests
Requests in Microsoft Power Platform consist of various actions that a user makes across various products. The following list describes what constitutes an API request, at a high level:
Power Apps - All API requests to connectors and Microsoft Dataverse.
Power Automate - All API requests to connectors, HTTP actions, and built-in actions from initializing variables to a simple compose action. Both succeeded and failed actions count toward these limits. Additionally, retries and other requests from pagination count as action implementations. As a basic rule, each step in a Power Automate cloud flow is an API request.
Dataverse - All create, read, update, and delete (CRUD), assign, and share operations, including user-driven and internal system requests that are required to complete CRUD transactions, as well as special operations like share or assign. These requests can be from any client or application and can use any endpoint. These requests include, but aren't limited to, plug-ins, classic workflows, and custom controls that are making the previously mentioned operations.
Entitlement limits
Entitlement limits represent the number of API requests that users are entitled to make each day. The allocated limit depends on the type of license that is assigned to each user. API entitlement limits are based on a 24-hour period, as shown in the following table.
Dataverse provides the ability to have identities that don't require a user license to interact with the service. The four types of users are:
- Application users
- Non-interactive users
- Administrative users
- SYSTEM user
Service limits
Apart from the daily API request limit, service protection limits are available that are specific to each service. As with the daily limits, service limits help maintain the quality of service by protecting the service from malicious or noisy behavior that would otherwise disrupt service for all customers.
