Hello
I am trying to write some queries in M and have not found much success.
I have a column with years ranging from 1985 to 2026. I want to find the min year and also the relative year (which is the year in the row relative to min year which is 1985)
When I write LIst.Min({[Calendar.Year]}), I get the correct result 1985 but when I expand my query it returns incorrect value
[Calendar.Year]-(List.Min({[Calendar.Year]}), it returns 0 on all rows. I want that if the row has 1987 as year number then teh relative year shoudl be 2.
When I write [Calendar.Year]-1985, I get the correct value 2
I want to use List.Min instead of harcoding the min year

Solved! Go to Solution.
List.Min({[Calendar.Year]}) just returns the minimum Calendar.Year of each rows Calendar.Year, in other words: just the value of each rows Calendar.Year value.
Instead, you must use the minimum value of the entire table column.
Example query:
let Source = #table(type table[Calendar.Year = Int64.Type],List.Zip({{1985..2020}})), MinYear = List.Min(Source[Calendar.Year]), #"Added Custom" = Table.AddColumn(Source, "WrongCode", each [Calendar.Year] - List.Min({[Calendar.Year]})), #"Added Custom1" = Table.AddColumn(#"Added Custom", "CorrectCode", each [Calendar.Year] - MinYear) in #"Added Custom1"
Thanks Marcel
I will try this but I was wondering that instead of getting the Advanced Editor and tweaking hte code, can i write it as custom column
when I edit my query..
Please let me know if I am not using the correct language and using M incorrectly here
