## replace values with If condition

Hi,

I am trying to replace values based on its own condition.

I want [Part number] column to be [common part].

If the part number starts with 999, then it becomes 9xxx

If the part number starts with AT99, then it AT.. and so on.

 Part Number Common Part 999-1-00 9xxx 990-1-11 9xxx 666-1-11 6xxx AT990-1-11 AT ICD-0000-0000 ICD-0000- ICD-1030-0000 ICD-1030-

Hi @dogburalHK82 ,

Here's the rule as I understand it: if the first "-" is preceded by numbers, return the first number as well as "xxx"; if the first "-" is preceded by both numbers and letters, return all of the letters; if the first "-" is preceded by all of the letters, return the entirety of what's preceded by the second "-".
You can put all of these M functions into the Advanced Editor:

``````let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WsrS01DXUNTBQitUBcQyAHENDMMfMzAzBcQxBkfN0dgHqMTAAE3ARQwNjmEgsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Part Number" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Part Number", type text}}),
let
PartNumber = [Part Number],
DashIndex = Text.PositionOf(PartNumber, "-"),
BeforeDash = Text.Start(PartNumber, DashIndex),
IsDigit = Text.Contains(Text.Select(BeforeDash, {"0".."9"}), "-") = false and Text.Length(Text.Select(BeforeDash, {"0".."9"})) = Text.Length(BeforeDash),
IsLetter = Text.Contains(Text.Select(BeforeDash, {"A".."Z","a".."z"}), "-") = false and Text.Length(Text.Select(BeforeDash, {"A".."Z","a".."z"})) = Text.Length(BeforeDash),
FirstChar = Text.Start(BeforeDash, 1),
FirstCharIsLetter = Text.Middle(BeforeDash, 0, 1) <> " " and List.Contains({"A".."Z","a".."z"}, FirstChar),
Result = if IsDigit then Text.Start(BeforeDash, 1) & "xxx" else if not IsDigit and FirstCharIsLetter and not IsLetter then Text.Select(BeforeDash,{"a".."z","A".."Z"})
else if IsLetter then let SecondDashIndex = Text.PositionOf(Text.Middle(PartNumber, DashIndex + 1), "-") in Text.Start(PartNumber, DashIndex + SecondDashIndex +1) & "-"
else null
in Result
)
in

The final output is as below:

Hi @dogburalHK82 , Please try to use Text.StartWith function in power query. Below is the Snip of code

Super User

where is your rules table? How do we know to group 999 after the first digit but AT990 after the second?
