Hi Guys,
I have the following table columns:
Posting date - Number of orders - Total sales
Now I want an extra custom column that sums the sales of every posting days - 5 days back.
So on 13-11-2019 i want that the custom column shows me the sum of total sales from the dates 13-11 / 12-11 / 10-11 / 09/11 and 08/11.
I know there are easy measures to fix this, but i really need it as a custom column in my table.
Can somebody help me?

Hi @Anonymous ,
You can refer to the following sample if it suitable for your requirement:
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("TZLLjQNRCARz8dnCNH9iWTn/NPZZGpg5lxo1BX9/L3zwEUa/3i9hqnDOZnt93z8kg1qJnaU09EI6yIuiubxkUjYom06iApIX8kFRBATCbFKxKaeoMveMC+UgNRIF9DS5UA0qJk1ms5pUb0oJrirJuBB4F2sKjWibgVgd7T/kjuhh8hjJ3vDYjlghUqfJ6djYmWskjmK2VORWWSV2aiZba45j3E6YpDJKW4blw7KhHqfBSgkj1XYu7AprpYy4VVrV59prRYssvLN7Zgoel4sTYveZKavFmtxDxHzWk/tPhM5I7vT9LnvMzJb21s2tlgJBDBrYnqvFk6pNJHV7rhZJMj2PeZLDbi8g53DT+9PXSyi1QUR1zqf8cKZHKG6ful4yKNIB/Hb//gM=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Date = _t, Amount = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Amount", type number}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "Rolling 5 Days", each Function.Invoke((current as date,tb as table)=> List.Sum(Table.SelectRows(tb,each [Date]>=Date.AddDays(current,-5) and [Date]<=current)[Amount]),{[Date],#"Changed Type"}))
in
#"Added Custom"

Hi @Anonymous ,
Can you please share some sample data for test? I 'm not clear your data structure and it is hard to coding formula without any detail information.

Hi @v-shex-msft
This is an example of the data.
I need an extra column that sums the total sales of 5 days back from that date.
So on 6-1-2019 it's a sum of 6-1 5-1 4-1 3-1 and 2-1

Great code! Thank you
Any advice to adding groups to the code? I.e. accumulate last five days' sales for each product?
Do i just need to ad an custom column with this code?
Table.AddColumn(#"Changed Type", "Rolling 5 Days", each Function.Invoke((current as date,tb as table)=> List.Sum(Table.SelectRows(tb,each [Date]>=Date.AddDays(current,-5) and [Date]<=current)[Amount]),{[Date],#"Changed Type"}))
Or what do i have to do, i'm quite new in the whole powerquery part.
When i try this, i get not the same result as you @v-shex-msft
HI @Anonymous ,
You can add a custom column and paste above formula in it:
Function.Invoke((current as date,tb as table)=> List.Sum(Table.SelectRows(tb,each [Date]>=Date.AddDays(current,-5) and [Date]<=current)[Amount]),{[Date],#"Changed Type"})
Notice: replace bold part with your column and steps name.
