I have a dataset which include two columns, ID and order time.
I want to create a new column to tag two type of value.
The definition of value is below:
New : before current order time never appear in previous time.
Existing : exclude "New" tag data.
I'm trying to create a loop like structure to filter time period and merge filter data to genarate what I want, but it's look like so inefficient...
sample data is below:
ORDER_TIME | ID |
2022/12/1 | a |
2021/12/3 | b |
I want to genarate tags below:
ORDER_TIME | ID | CUSTOMER_TYPE |
2022/12/1 | a | EXISTING |
2021/12/3 | b | NEW |
Is there any faster way to tagging data?

Hi @ronhs ,
According to your description, here's my solution. Add a custom column in Power Query.
if [ORDER_TIME]=List.Min(#"Changed Type"[ORDER_TIME])then"New"else"EXISTING"
Get the result:
Here's the whole M syntax, you can copy-paste it in a blank query to see the details.
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMtI3BCIlHaVEpVgdsIghSMQYKJKkFBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ORDER_TIME = _t, ID = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"ORDER_TIME", type date}, {"ID", type text}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "CUSTOMER_TYPE", each if [ORDER_TIME]=List.Min(#"Changed Type"[ORDER_TIME])then"New"else"EXISTING")
in
#"Added Custom"
I attach my sample below for your reference.
