Replicating excel formula | precedent referencing
Hello community, Need help in replicating the following formula in DAX or in power query - In Excel we can easily use precedent referencing but in dax or power query I haven't found anything,...
let Source = your_source_table, data = List.Buffer(Source[Total engine hours]), max_count = List.Count(data), pulse = List.Generate( () => [i = 0, p = 0], (x) => x[i] < max_count, (x) => [i = x[i] + 1, p = if (data{i} >= data{x[i]}) then x[p] + data{i} - data{x[i]} else x[p]], (x) => x[p] ), out = Table.FromColumns(Table.ToColumns(Source) & {pulse}, Table.ColumnNames(Source) & {"Pulse"}) in out
Hi, Anonymous
let
Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
data = List.Buffer(Source[Total engine hours]),
max_count = List.Count(data),
pulse =
List.Generate(
() => [i = 0, p = 0],
(x) => x[i] < max_count,
(x) => [i = x[i] + 1, p = if (data{i} >= data{x[i]}) then x[p] + data{i} - data{x[i]} else x[p]],
(x) => x[p]
),
out = Table.FromColumns({data, pulse}, {"Total engine hours", "Pulse"})

let Source = your_source_table, data = List.Buffer(Source[Total engine hours]), max_count = List.Count(data), pulse = List.Generate( () => [i = 0, p = 0], (x) => x[i] < max_count, (x) => [i = x[i] + 1, p = if (data{i} >= data{x[i]}) then x[p] + data{i} - data{x[i]} else x[p]], (x) => x[p] ), out = Table.FromColumns(Table.ToColumns(Source) & {pulse}, Table.ColumnNames(Source) & {"Pulse"}) in outI believe this will definitely help, thank you so much!
Do you know if there's a way we can achieve the same through DAX?
DAX - most likely yes but I am not a DAX guy (yet) 😎
