YTG & YTD Calculation by using custom list
I've one use case where I've create list which includes YTD & YTG as list item.
Then I've create a mapping module between Time & YTD & YTG list item as shown in below screenshot.
But when I am using sum to get data which is dimensioned by YTD & YTG List, result is showing 0.
Can anyone explain why I am getting 0 values after using sum.
N.B I've achieved this by using timesum later but needs to understand why sum is not working after having mapping between time & list.
