Hi Bram Boerman ,
Welcome to Microsoft Q&A platform and thanks for posting your query here.
As per my understanding, you are trying to update the Dynamics 365 refresh rate.
You can perform asynchronous data-refresh operations on your Azure Analysis Services tabular models.
Data-refresh operations can take some time depending on a number of factors including data volume, level of optimization using partitions, etc.
The base URL follows this format:
https://<rollout>.asazure.windows.net/servers/<serverName>/models/<resource>/
For more details, kindly checkout the below documentation: Asynchronous refresh with the REST API
To create azure support ticket, you can go through the steps mentioned in the documentation: Create an Azure support request . If you have a support plan you may file a support ticket. In case you don't have a support plan , I will enable a one-time free support request for your subscription. Please do let us know.
Hope it helps. Kindly let us know if you have any concerns.
