DirectQuery Table Grand Total Percentage Calcaluation Incorrect

[jhughes51]

I cannot get the grand total percentage to calculate correctly.  I've searched this forum up and down and cannot find an answer that works.  This is a DirectQuery report.  Below are examples of the data I'm using. 

The First picture is the Power BI Table with no Grand Total Percentage, 2nd picture is Power BI table with Grand Total Sum Percentage, 3rd is a Sharepoint Dashboard currently in place that calculates grand total percentage correctly.

Pctg Column is built in a SQL query as a decimal, then converted into a percentage in Power BI.

Any help anyone could provide would be greatly appreciated!

Hi @jhughes51,

That's because the grand total is just a total of all the percentages, which isn't the right way to calculate the grand total percentage. I would suggest you use a measure instead.

Measure =
DIVIDE ( SUM ( 'table'[RptTtl] ), SUM ( 'table'[Goal] ), 0 )
