Finding differences between tables

[irnm8dn]

I have two datasets that need to be compared, with Power BI displaying the differences between the two columns.

For instance, I have two datasets (.csv files) from two different systems, both with a columns identified "Order Number".  Is there a simple DAX statement that will tell me if I have a match (or not) between the two files?

Thanks!

HI @irnm8dn

The EXCEPT function in DAX can give you a list of values that happen to be in one table, but not the other (and vice versa).  If you create a calculated table using this function you can quickly focus in on any differences.
