Concatenate down a column based on another column?

[slatesha]

I would like to create a custom column to concatenate the ORDERNUM number based on SHIPPLANT. 

i.e.

011 - 04779,04780,04782,04784

022 - 04872,04902

026 - 04827,04828

Any Ideas?

You can use GROUP BY and modify the code as follows.
Create a blank Query, go to the Advanced Editor, clear the existing code, and paste the codes give below and follow the steps.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("XcnBCQAgCADAXXz7UInUWcT91wikAn0eFwG0VB0QiBkSy0bDMryaTetFrp26TbS8v+05Dw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ORDERNUM = _t, SHIPPLANT = _t]),


    #"Grouped Rows" = Table.Group(Source, {"SHIPPLANT"}, {{"ORDERNUM-CONCAT", each Text.Combine([ORDERNUM],","), type nullable text}})


in
    #"Grouped Rows"
