This error message typically occurs when a calculated table in Power BI is referenced in a query, but the evaluation of the expression used to create the table has resulted in an error. The calculation in the calculated table is either invalid or there is a problem with the data it references.
Here are a few steps to help resolve the issue:
Check the expression used to create the calculated table: Ensure that the expression is valid and that all the required columns are present and correctly referenced.
Verify the data sources: Make sure that the data sources used in the expression are valid and accessible.
Check the relationships: Ensure that the relationships between tables are correctly defined and that the calculated table is referencing the correct columns.
Refresh the data: Try refreshing the data sources used in the expression to make sure that the data is up-to-date.
Debug the expression: If the issue persists, use the Debug mode in Power BI Desktop to step through the expression and identify the issue.
If you're still unable to resolve the issue, please provide more information about your setup, including the expression used to create the calculated table and any related error messages. This will help provide a more detailed answer.
