    It depends on your requirement, if you are good at T-SQL, you can create SQL Server function and call the function in Power BI Desktop to shape data or filter data. And when you have large amount of data and columns in the raw tables, and you are clear about which columns and rows are useful in Power BI report, it is better to use SQL Server query/function to limit the columns and rows, which will boost performance on Power BI side. Many complex steps against large table  in Power BI Desktop query editor will put pressure on memory.

    However, if you are not familiar with T-SQL, you can import all data into Power BI Desktop and transform data in Query Editor as it is easy and convenient to use.

    Regards,
