Thanks for your fast response.
I'm looking for formula which shows the portion of the vaule 0 only. Additional if the cell of the source is empty, the cell for the corresponding portion value should be empty.
I’m able to achieve this with the formula
If( Is Missing( :Value ) == 0,
Col Sum( If( :Value == 0, 1, :Value > 0, 0, . ) ) / Col Number( :Value ),
.
)
Despite getting the right result, I am wondering whether there is a better way to solve this. In particular with regards to apply this formula to sub groups.
