Recursive issue

Hello everyone,

 

I have a table similar to this one :Capture.PNG

So the first column is the name of an object and the generation (I, II, III, IV, ...), second column correspond to the previous generation of this object, and the last one is the name of a contact associated to this object. I would like to have a table similar to this :Capture2.PNG

So I would then be able to filter on my report on a Name, and see ALL the previous generations of this object and the contact associated.

I have coded similar things in Python but I have no clue about how to do it on Power Bi (M language or DAX).

 

Thank you very much for your help !

Gautier

try this M code

NewStep=let gens={"IV","III","II","I"} in #table(Table.ColumnNames(PreviousStepName),List.TransformMany(Table.ToRows(PreviousStepName),each let a=List.Skip(gens,(x)=>not List.Contains(Text.Split(_{1}," "),x)) in if a={} then {_} else List.Transform(a,(x)=>Text.Combine(Splitter.SplitTextByAnyDelimiters(gens)(_{1}),x)),(x,y)=>{x{0},y,x{2}}))
