Create table from existing data set in power query excel

[10500438]

I have a large dataset that is in power query from multiple excel spreadsheets. I want to create a new smaller table which would include only two columns from the large data set. one column is Name and the other column is a Wage % measure. The wage % measure should be the product of the rows (meaning if there were 3 rows in the large data set, I would get one row in small dataset but the wage % would multiple each row to arrive at the new one line answer).

Is this possible in power query, I know how to do it in Power bi, but I cannot do it in excel power query.

Hello @10500438 

there should be no difference for Power Query Excel or Power BI when it comes to basic functions.

Check out this solution. It applies a Table.Group with a List.Product-function

let
	Source = #table
	(
		{"Name","Wage%"},
		{
			{"A","0,05"},	{"A","0,04"},	{"A","0,1"},	{"B","0,3"},	{"B","0,5"},	{"B","0,3"},	{"C","0,2"},	{"C","0,1"}
		}
	),
    ChangeType = Table.TransformColumnTypes(Source,{{"Wage%", Percentage.Type}}),
    Group = Table.Group
	(
		ChangeType, 
		{"Name"}, 
		{{"Product", each List.Product([#"Wage%"]) ,  Percentage.Type}})
in
	Group

Copy paste this code to the advanced editor in a new blank query to see how the solution works. If this solution fits your need, copy and past a part of it and implement it in your query

I feel like we are on the right track, but I cannot figure out how to implement this into my solution. I have only been using Power BI and Power Query for a short while. How can I upload my excel file for you to see what I am working with?

In the meantime here is my output from my query, 

what I am trying to do is have the same output as below, but any Unique Key that has more than one line item, The Unit Yield column should be mulitplied times each other and have one single row that represents the result.

The data set is very large because of the mulitple times products move through a mill area, so to get a smaller set, I can multiply mill areas times each other to get the correct result per mill area. Thanks in advance for all your help.

Hello @10500438 

Select every column except the last one --> Tranform --> Group by 

Set the group by like this

change the formula in the formula bar the part of the funciton like this

each List.Product([Unit Yield])

All though I can get this to work on the numeric columns, grouping by sales order and sales item, I cannot get it to work when I group by all the columns shown, I am getting a DataFormat.error we couldn't convert to a number Details 1P01780000.

Any thoughts as to why? Maybe because the Column Mill Area is text characters?

I figured out I needed to change the type to numeric,, thank you!! It works great!!

Thank you for all your help so far!!
