Calculate sum of column in query editor

[KaterineCAA]

I have the following table in the query editor of PowerBI.

I would like to either :

- Calculate the sum of "Nombre de répondants" and add it in a new column (it would be the same value for every line) or

- Calculate the proportion of "Nombre de répondants"

As a result, I would have one of the two new columns in the second image. (My 249 will varie in the future)

I would prefer doing it in the query editor.

Thank you!

@KaterineCAA

To achieve your requirement, you can refer to following steps:

1. In Edit Queries, go to Add Column and add a Custom Column.
2. Use Power Query expression like: List.Sum(#"Changed Type"[Nombre de répondants]) to get the sum of Nombre de répondants.
3. Then for Proportion, you can simply use expression like: [Nombre de répondants]/[ Nombre de répondants Total]
