Error while saving Notebook from my workspace to a premium workspace (Fabric Trial account)

Hi BenBlackswan,

Thanks for your follow-up and no need to apologize. What you asked is a good question, and the confusion is very common, especially with how tightly integrated Microsoft Fabric and Power BI have became. 

Even though Notebooks in Fabric are Spark-based and run on the Data Engineering or Data Science experience, certain actions like saving or moving a Notebook into a shared Premium workspace involves Power BI in some way or another like Fabric Workspaces = Power BI Workspaces, all Fabric artifacts (Notebooks, Lakehouses, Pipelines, Dataflows, etc.) live in Power BI workspaces. When you perform operations across workspaces, like saving a Notebook into a Premium workspace, it goes through Power BI’s REST APIs and security model. 

Even though you’re using a Spark Notebook, saving it into another workspace still requires Power BI write permissions. If your account doesn’t have a Power BI Pro or PPU license, you’ll hit errors like "PowerBIFeatureDisabled".

If I misunderstand your needs or you still have problems on it, please feel free to let us know.  

Best Regards,
Hammad.
