Troubleshooting Microsoft Dynamics 365 Writer

This section highlights known limitations and Microsoft-imposed restrictions when using the Dynamics 365 Writer, along with typical errors and suggested workarounds.

  • Microsoft Dynamics 365 Writer discards all events when the BatchPolicy’s eventCount exceeds 1000 due to a limitation imposed by Microsoft.

    Error: "The current change set contains too many operations. A maximum number of '1000' operations are allowed in a change set."

  • Microsoft Dynamics 365 Writer discards update events if an Entity Reference property is included as a column. As a workaround, exclude these columns from the source.

    Error: “CRM does not support direct updates of Entity Reference properties; use Navigation properties instead.”

  • If API requests exceed the defined rate limits, Dynamics 365 may throttle requests and return an HTTP 429 (Too Many Requests) response. Throttling thresholds vary based on environment type, user roles, and other factors such as concurrent operations and overall request volume across tenants.

    For detailed information, refer to the Microsoft API limits documentation.
