How to create a % column

Question

Hello, I have a custom field which can assume 4 values, one for each of these columns:

I need to add a column where I show the percent of RETE column compared to the sum of each row. For instance at row 4 this percent should be 24/(47+0+24+0) = 34%.

I guess I need to create a new calculation but I have no idea how to start.

Any suggestion?

Thank you

I solved by creating a Key metric for each column and a Calculation for the percent calculation
