create new groups from existing table

[adavid999]

Dear all,

I am working in power query/excel. Is it possible/uncomplicated to group some items in an existing external odata table into new categories so that any measures/displays pick up both new groups and individual elements? I.e. a new Region group as below xyz showing an average of % and a sum of resp?

Region	%	resp
x	5	2
y	10	3
y	15	4
*new Group xyx	10	9

Ideally I would not have to change any existing pivot tables/measures/displays. Please could you let me know how to do this, or point to a helpful resource?

Many thanks,

A

Hello @adavid999 

you can try to add a new column with the new region name

Group by this column, applying exactly the measures you want and after that combining both tables. Here the code for a short example

let
	Source = #table
	(
		{"Region","%","resp"},
		{
			{"x","5","2"},	{"y","10","3"},	{"y","15","4"}
		}
	),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"%", type number}, {"resp", type number}}),
    #"Added Custom" = Table.AddColumn(Table.RemoveColumns(#"Changed Type", "Region"), "Region", each "group xyy"),
    #"Grouped Rows" = Table.Group(#"Added Custom", {"Region"}, {{"%", each List.Average([#"%"]), type number}, {"resp", each List.Sum([resp]), type number}}),
	Combine = Table.Combine({#"Changed Type", #"Grouped Rows"})
in
    Combine

Copy paste this code to the advanced editor in a new blank query to see how the solution works.

Hi @Jimmy801 I think that would do it - so simple! Even a new column in the existing table should work shouldn't it?!

Thanks,
