Hi @NovaBI , Thank you for reaching out to the Microsoft Community Forum.
The issue with your blank calculated columns in Power BI Desktop comes down to how Dataflow Gen2 handles computed entities. These tables calculate data in memory during preview, but unless they're explicitly set to "Enable Load", their results, especially calculated columns, don’t get written to the Lakehouse, which is what Power BI queries. This applies not just to the final table, but to any upstream computed tables feeding into it.
When I said “non-computed table”, I meant a table that does not perform additional transformations on computed entities and therefore doesn’t become a new computed entity itself. In your case, instead of duplicating logic which re-creates another computed table, you should right-click your final table and select “Reference”. This creates a new table that simply points to the final result. As long as you don’t add any new steps, it won’t become a computed entity again. Then turn on "Enable Load" for this new table so it gets persisted to the Lakehouse.
Also, double-check that any upstream computed tables, like those used in merges are also being loaded. If not, even a reference might not fully resolve the data. Once that’s in place, your calculated columns should show up properly in Power BI Desktop.
If this helped solve the issue, please consider marking it 'Accept as Solution' so others with similar queries may find it more easily. If not, please share the details, always happy to help.
Thank you.
