    Hi Anonymous,

     

    Does that make sense? If so, kindly mark my answer as a solution to close the case.

Hi Anonymous,

 

You’d better not to go with modeling at power BI.

 

Setting them up in Power BI takes more time. I don't find it quite as easy as doing it in SQL. For example, Power BI doesn't allow you to join two tables together on more than one column. So if you need to join two tables together on more than one column, you need to create another column in Power BI to concatinate the other columns, and then join on that. joins in DAX are costly on performance, so your reports may be slow, which could be a disaster.

 

Regards,

Frank
