ADDCOLUMNS()? No problem!

In this way, the output will be consistent since ADDCOLUMNS() will always evaluate over the row context by default. In this exercise, you'll expand the CaliforniaPR table with the Profit Ratio from Chapter 2.

If you have lost any progress, close any open reports and load 3_2_addcolumns.pbix from the Exercises folder on the desktop.
