Hierarchy with same child name for different parents

[Anonymous]

Hi,

I'm working with a parent-child hierarchy but in which some child values have different parents. For instance:

Child	Parent
USA	Country
France	Country
Revenues	USA
Revenues	France

The hierarchy function PATH() does not support a hierarchy like that with same child for different parents. Is there any way to work with this kind of hierarchy?

Thanks!

country	USA	Revenues
Country	France	Revenues

recast your hierarchy, the parent "country" has 2 children, "USA" and "France", each of them has one child "Revenues"

Yes, that's the hierarchy of the example. But now imagine that you have a table of thousands of rows instead of just 4. Then to build up the hierarchy you would use the PATH( <ID_ColumnName>, <Parent_ColumnName>) function, but this function 

returns an error if parent_columnName value is different for those duplicates  (which is the case).

Then my question was, how to build the hierarchy anyway? I'm afraid it's not possible...

Try this custom Column from Query Editor

=let //Define your columns below
 c=[Child],p=[Parent],mytable=#"Changed Type",pc="Parent",cc="Child" 
  in
let mylist={c} & List.Generate(()=>[x=0,y=p,w=1],each [w] > 0,each [z=[y], 
x=Table.Column(Table.SelectRows(mytable,each Record.Field(_,cc)=z),pc),y=x{0},w=List.Count(x)
],
each [y])
        in
Text.Combine(List.Reverse(List.RemoveItems(
List.Transform(mylist,each Text.From(_)),{null,""})),"|")
