Relatively new to Power BI. Looking for some guidance?
Loaded up two tables with very similar data with different names, only one column differs in values. I would like to compare the two values together to understand variance between the two? Is this creating a measure or using relationships? Tried to use relationship however got error message regarding columns not having unique values?
If i load up two different tables, "Sales 1" and "Sales 2" which have all the same column headers except one where Sales 1 has"This year" and Sales 2 has "last year" where the values differ and i want to compare these two columns to understand the variance, how could this be done?
You can use “Merge Queries “ feature to join the two tables tomake the "last year" column and "This year" column in a single table such as Sales 1, then create a new column in Sales 1 using formula like: Difference = 'Sales 1'[This year]-'Sales 1'[NewColumn.Last year] to compare values of the two different columns. For more details about how to use Merge Queries “ feature, please review this blog: http://radacad.com/relationship-in-power-bi-with-multiple-columns .
And you can check the example in this attached PBIX file. If you don’t get expected result, please help to post sample data of your scenario.
Thanks, Lydia Zhang
