Power BI Refresh Error:
Please rebuild this data combination
What does this error mean?
Power BI detected a potential privacy violation where data from one source might be sent to another. This error is related to the privacy firewall and forces you to reconfigure data source trust levels.
Common causes
- 1Two or more data sources with different privacy levels are combined in a single query
- 2A query parameter that originates from one source is used in another source's query
- 3Privacy levels changed or were cleared after updating Power BI Desktop
- 4A data source was added to the query without configuring its privacy level
How to fix it
- 1Open Power BI Desktop and navigate to File → Options → Current File → Privacy
- 2Select 'Ignore the Privacy Levels and potentially improve performance' to bypass the firewall for trusted internal data
- 3Or, configure explicit privacy levels: Public (no sensitive data), Organizational (internal only), or Private (cannot be combined with others)
- 4In Power BI Service, update each data source's privacy level under dataset Settings → Data source credentials
- 5If the error persists after setting levels, open the Power Query Editor and remove any steps that pass source A's values into source B's query
