Hey Guys,

Here the answer !

I have found this on the internet and adapted to my Case

https://stackoverflow.com/questions/65342143/power-query-table-group-with-a-dynamic-list-of-aggregat...

This adapted to my situation is 

= Table.Group(#"Lignes triées", #"Lignes filtrées1", List.Transform(#"Detection des Tailles 11 On garde une liste", (C)=> {C, each List.Sum(Table.Column(_,C)), Int64.Type}))

in simple words

= Table.Buffer(Table.Group(#"Step in which i need this", #"List of columns i want to keep", List.Transform(#"List of columns i want to aggregate", (C)=> {C, each List.Sum(Table.Column(_,C)), Int64.Type})))

You're the gods guys!
