This is an excellent topic! Here’s my custom function designed to achieve something similar.

= (tbl as table) =>
let
_type = Table.TransformColumnTypes(tbl,Table.ToRows(Table.ReplaceValue(Table.Distinct(Table.UnpivotOtherColumns(tbl, {}, „Attribute“, „Value“), {„Attribute“}),each [Value],each Value.Type([Value]),Replacer.ReplaceValue,{„Value“}))),
total = _type & Table.PromoteHeaders(Table.Transpose(Table.ReplaceValue(Table.SelectColumns(Table.AddColumn(Table.Profile(_type), „Sum“, each [Average] * [Count], type number),{„Column“, „Sum“}),
each [Sum],each if [Column]=Table.ColumnNames(_type){0} then „Total“ else [Sum],Replacer.ReplaceValue,{„Sum“})), [PromoteAllScalars=true])
in
total

Thanks‘ for sharing this. There was lots to learn from the solutions provided by the very well recognized PQ gurus. It was a very good exercise too.

Here is the solution that I came-up with:
let
Source = Excel.CurrentWorkbook(){[Name=“Datenbasis“]}[Content],
ToSum = {„January“,“February“, „March“, „April“, „May“, „June“, „July“, „August“, „September“, „October“, „November“, „December“},
Sums = List.Transform (Table.ColumnNames(Source), each if _=“Cost centre“ then „Total“ else if List.Contains(ToSum,_) then try List.Sum(Table.Column(Source, _)) otherwise _ else null),
SumTable = Table.PromoteHeaders(Table.Transpose(Table.FromColumns({Table.ColumnNames(Source), Sums}))),
Combine = Table.Combine({Source,SumTable})
in
Combine
