Indexing on SQL Server
Jimmy,
Thank you

Hi odeddror,
If you connect to your sql server instance using import mode, you can add an additional index column in power query, click Query Editors-> Add Columns-> Index Column. If using direct query/live connection mode, you should create index column in your database because power bi doesn't allow users to create any custom columns in power query or calculate columns in DAX in direct query/live connection mode.

Jimmy,
Thank you for the explanation, my question was should I create an index in SQL Server or not?
Is Power BI its own machanism to handle that?
Thanks

That's based on your requirement. For example, if you need to achieve some result in some measures based off the relationships between up and down rows, you can create an index column.

Yes, like SQL script in SQL Server, you can also wirte Power Query or DAX function to use the index column.
