Power modeling tools

External data modeling tools can apply modifications and have Power BI synchronize those changes with the report canvas. This synchronization is so those modifications are consistently applied in Power BI visuals. For example, external data modeling tools can override the original format string expression of a measure, and edit any of the measure properties including KPIs and detail rows.

External tools can also create new roles for object and row-level security, and add translations. Write operations are limited because Power BI Desktop must remain in-sync with the external modifications, therefore the following operations are not supported:.

When a tool is registered, and includes an icon, the tool appears in the External Tools ribbon. However, many tools, like SQL Profiler typically do not because the installer they do have does not include creating a registration file for Power BI Desktop.
