power query hierarchy's calculation

[montibellin]

Hi Guys,

I'm searching a method to calculate in an additional column the hierarchy on column1 based on the parent relationship reported in column2. 
Basically the root level is Leve1 when "location" is reported on Column2.
below a picture that shown what I need

Hi @montibellin ,

try this 

= Table.AddColumn(#"Changed Type", "Custom", each if [Parent] = "Location" then "Level 1" else if [Parent] = "Europe" or [Parent] = "Africa" or [Parent] = "Oceania" or [Parent] = "Asia" or [Parent] = "America" then "Level 2" else "Level 3")

it works only in this case, when the values don't change. Otherwise I need to update code every time.

I'm found a solution using Merge funciton applied on the same table.

in the result it's necessary to select "lev 1", that can be renamed in "lev 2", then filter "lev 0" = "location"
this is the result
