How to create new columns based on value from another column

[Anonymous]

Hi all, 

I would like to create a ew column where results are shown based on one value from a list of values from another column. For example, if there are 10 item numbers each for 7 regions, that would be 70 item numbers in total. But I would like to create 7 diferent columns, one for each region, like item number region A, item number region B, etc.. Please tell me how I can do it. Thank you.

Hi , @Anonymous 

According to your description, do you mean you want to convert your table like this?

If this , it can be realized in Power Query Editor.

We can put this M code in "Advanced Editor" to refer to :

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("bc+tDoAgFIDRd7mZIBfk5xGsVkZkzqAW338aZGPuq6edUmRt236dVowsdzusVPM3BXNgHmweTD8LYBEsgWUwOw3oOlpCJXSEnnDc+I6BMBImwgyo76g+", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Region = _t, Item = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Region", type text}, {"Item", type text}}),
    Custom1 = Table.Group(#"Changed Type","Region",{"test",(x)=>x[Item]}),
    Custom2 = Table.FromColumns(Custom1[test],Custom1[Region])
in
    Custom2

Then we can get the table we want to :

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!

Hello,

You could do a measure that counts the item numbers and then visualise this measure by region name so it would show you the count of item numbers for each region, instead of creating 7 columns.

If I answered your question, please mark my post as solution so it would appear to others, Appreciate your Kudos👍

Thank you for your answer @Idrissshatila .I actually need to create columns because that is the requirement of the customer, as they want to see separate lists of item numbers in a table format, specific to each region. Hence the question.
