Hi, I need to change a query from table A to table B as below.
Basically I need to get the difference between the latest and the second latest date for each product ID.
Is there any way to do this in Advanced Editor?
Solved! Go to Solution.
See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTIyMDLUBUKlWB1kASMsIsYQISOIkJGuqS6agLmuOaqABboKoICBUmwsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Product ID" = _t, #"Sold Date" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Product ID", Int64.Type}, {"Sold Date", type date}}),
#"Grouped Rows" = Table.Group(#"Changed Type", {"Product ID"}, {{"Gap between last 2 days", each Duration.Days(List.Last(_[Sold Date])-List.First(List.LastN(_[Sold Date],2))), Int64.Type}})
in
#"Grouped Rows"

#"Grouped Rows"
It works great! Thank you.
