SUM doesnt work

Hi MIKAOKSA ，

9.58 is the  result of sum(9.67,14.33) * devide( sum(4,73,2.66),sum(5.93,12.59)), as measure is used in context,it will also calculated in the total field, not only simply sum the rows in the column.

I have 2 suggestions  for you:

1.convert  the other measures to calculated columns, and you will see :

2. modify your measure as below:

Goal time on own part = 
var a = SUMMARIZE('Table (2)','Table (2)'[Index],"A",SUM('Table (2)'[Time on work/Employee])/SUM('Table (2)'[Total completion time of work]),"B",SUM('Table (2)'[Goal time whole work]))
return
SUMX(DISTINCT(a),[A]*[B])

And you will see:

Here is my .pbix file.
