📊 WHAT IS POWER BI?
Power BI is a business analytics tool by Microsoft. It creates a working environment suited for normal users, meaning tasks such as data extraction, cleansing, analysis and storytelling; these are made easily-accessible to citizen-users, and extendable for technical users. At face value it provides visually-stunning, interactive dashboards, but it’s built on top of so much more.

Thanks a lot, I didn't know how to make a SQL Select/Union in DAX and you demonstrate it with excellence.

[alexking]

This was perfect, exactly what I was looking for :-)

Thanks! Very good tip and very well explained.

As a best practice, if you append in Power Query, should you turn off enable load on the original queries so that only the full table gets loaded? If you don't do this, when you load the tables, will it effectively update the data twice for each table?

[shwetkumar]

Can we update, insert two table in dax

[vineetbhushan]

Can we append a table and power bi dataset other report

[JJ_TheGreat]

If you need to both Append and Merge, is it better/more efficient/effective (from a memory standpoint, etc.) to Merge and then Append, or Append and then Merge?
Thanks.
