Calculate Percentage Difference Between Table Column Totals
I have a simple table showing values for two different years of data. I want to show the total year to year percentage difference in the last column (YOY % Change) in the total row at the bottom of the table. Here is the table.
In Excel, I would just drop a simple formula in the cell. How do I show the percentage difference between the table column Totals? In effect (JV_tot - JV_tot_17)/JV_tot_17 for the total row?
Thanks for your help. I am obviously new to Power bi.
Hi ScotsSailor,
I tried re-creating your requirement and it seems to work the way that you are expecting it to work
I have created 2 measures and below are the codes for them
Measure = SUM(Table1[JV_Tot]) - SUM(Table1[JV_tot_17])
Measure 2 = [Measure]/SUM(Table1[JV_tot_17])
The Below is the screenshot
One possiblity why the percentage not getting displayed in totals is, you have created the YOY Change and YOY% Change as columns and given don't summarize as the aggregation rule for YOY% change
Also keep in might for this creating YOY% Change as column will not give the right values for your total even if they start appearing in totals
Hope this solvesyour issue!!!

It did indeed solve the issue and you guessed it, I was using columns instead of measures. I'm very greateful for your prompt response. I am just beginning to understand Power BI, having spent quite some time with PowerQuery and Pivot tables.
