Can't 'change source' in data source settings for Custom Connector

[tylersbrown01]

The Power BI team recently released the Data Connector SDK, allowing developers to develop custom data connectors in M to allow business users a more user-friendly experience when connecting to their databases. It's great for database companies like us, because we can provide a better interface for helping our users select their data.

There is one issue though... the 'change source' button in the 'data source settings' is disabled. This means that a user has no way to change the underlying data in a report environment. This feature is our 'bread and butter' and is possible with a vanialla OData query. So why can't we do it with a fancy connector? Am I missing somethg here? Is there another way to do it? By requesting new data (instead of modifying the existing tables) - all my dax measures and columns are useless because they are tied to the old datasource.

Thanks for reporting that. The Data Connector SDK is still in preview and currently it is only supported in Power BI Desktop. For any feedback, you can submit at Power BI Ideas.
