Hi AndresPesca ,
The version of your Power BI Desktop is the latest one. As the description in your original post, it seems like the dataflow only include one table. Could you please provide the following info for that dataflow?
- Is there a significant amount of data being processed?
- If it exist complex transformations or joins in your dataflows?
