I have a table in a Power Query, and would like to reference the maximum value of another column.
So let's say this is my table in Power Query:
then I'd like to add a Custom Column "Range", with the formula
= if [Value]<0.33*MAX([Value]) then "0-33%" else if [Value]<0.66*MAX([Value]) then "33-66%" else "66-100%"
but of course "MAX" isn't a formula in Power Query.
The end result should be something like (some ranges may be incorrect, but you get the idea)
I'm not a Power Query Power User (as you have guessed), so preferably using functions in the ribbon...

Before that add step like
maxValue = List.Max(prevStep[Value])
and use it in calculations

Thanks for your reply!
How much of that can be done without the advanced editor?

That significantly complicates the task. It could be like:
1) query source table
2) Reference source table, rename as maxValue
3) select in it Value column, Transform->Statistics->Maximum
4) Reference source table, rename reference as Range
5) Add Column -> Custom Column -> name as max -> =maxValue
6) Select Value column -> Add Column -> Standard -> Percentage Of -> from drop-down near Value select Use Value or column -> select max
7) Select Percent Of -> Transform -> Standard -> Divide -> 100
9) Add Column -> Conditional Column and here combine something like
10) Select columns ID, Value, Range
11) Home -> Remove Columns -> Remove Other Columns (from drop-down menu)
12) Home -> Close & Load To -> Table -> select desired options

@Sergei Baklan Could you clarify what you mean by "2) Reference source table" please?

If you right click on any query you will see Reference in the menu
If click on it new query will be created with reference on first one

@Sergei Baklan Fabulous! It was the reference part that I didn't know about, your explanation makes it all very clear now. I reproduced your steps and understand now, thank you!
