High severitydata source
Power BI Refresh Error:
DM_ErrorCode_BackEnd_QueryExecutionFailed
What does this error mean?
The Analysis Services engine (the backend that processes your data model) failed while executing a query against the data source. This error wraps backend execution failures that occur after the gateway has successfully retrieved the data.
Common causes
- 1A measure or calculated column uses a DAX function that references a column that no longer exists
- 2Row-level security expressions contain syntax errors or reference invalid tables
- 3A relationship in the data model references columns with incompatible data types
- 4The data source returned values that cannot be cast to the column's defined type
- 5A partition query failed because the underlying source schema changed
How to fix it
- 1Open the dataset in Power BI Desktop and attempt a manual refresh — the error trace in Desktop is usually more detailed
- 2Check for broken DAX measures using the 'Performance Analyzer' or by inspecting the Error list in the model view
- 3Verify all relationships point to columns that still exist and have compatible types
- 4Review any calculated columns or RLS expressions for references to removed columns
- 5If using partitions (Premium), check each partition's source query in Tabular Editor or SSAS Management Studio
