Excel Export Errors Occur Frequently in One Power BI Service Workspace but Not Another
Hello, Please excuse any awkward wording, as I am not very comfortable with English and am writing this post with the help of a translation tool. I am experiencing frequent export errors with a Power BI report published to Workspace A in Power BI Service. The exact same PBIX file has also been published to Workspace B, but the report works without any export errors in Workspace B. I have also confirmed that the report works correctly in Power BI Desktop. The settings in Workspace A and Workspace B are basically the same, as far as I can tell. Both workspaces use the same capacity type, and there is plenty of available capacity. The capacity limit is 10 GB, and the current usage is well below that limit. My questions are: What could cause export errors to occur in one workspace but not in another, even when the same PBIX file is used? Are there any workspace-specific settings, service-side limitations, or other factors that I should investigate? Could differences in the semantic model, data source connections, or the Power BI Service environment cause this behavior, even if the workspace settings appear to be the same? Is there anything else I can check to identify the cause of this issue? I would appreciate any suggestions or insights that could help me troubleshoot this issue. Thank you for your help!
The column 't5.c514' of the table was not found
The error indicates that the t5.c514 column is being referenced during the underlying query/model processing but is not available in the returned result set. Captured the query execution using DAX Studio → Server Timings to identify the underlying SQL generated for the DAX query. Reviewed the SQL generated in Server Timings and validated the SQL statements executed against the backend. No reference to t5.c514 was found in the generated SQL. The generated SQL does not contain a column or alias explicitly referencing t5.c514, even though the Power Query/Mashup error reports that this column is missing. To further isolate the issue, we selected individual columns from the _Employee Assignment Information table and executed separate DAX queries to validate whether the issue was specific to a particular column. But the issue did not occur when selected few particular columns, can someone please help, what exactly the c514 column the engine to mapping to ?

Run R/Python scripts in PBI Power Query
I want to use R/Python scripts to transform data in PBI Power Query, but I cannot see those options under the "Transform" ribbon now. Does anyone have any ideas to make it show up? Thank you. I'm using the September 2026 version of PBI. There is no show of "Run R Script / Run Python script": This is the snapshot that I usually see on the very right shown two icons that I want to bring back.
Cannot Set Custom Query on "new" Power Query
Hi, Following latest September 2026 Power BI Update, I'm not able to edit a native database query on Power Query, the option has vanished. The query is still showing in the m-query editor, and I'm getting the data with the native query. But the option to add/edit the query from the option menu has vanished. How it used to display, and how it's on the Power Query documentation. Import data from a database using native database query - Power Query | Microsoft Learn Thank you in advance for your support!
