Power Query - Custom Sum Column

[braga_felipe]

Hello everyone, thank you for the help.

I need to create a custom column in power query editor in advanced editor. I have a column1 with the code of different products (every product have other lines with other valures) and a column2 with a specific characteristic (decimal value). I have to create another column removing the duplicates of the column1 and sum the value of each specific characteristic, like in image below. 

Could you help me? Have a easyer way to do this in power bi? I know how to do this in Excel, but i need to do this in Power Bi to avoid data treatment every single time i will use the analysis.
