Custom column using VLookup?

(0) ShareShare
ReportReport
Posted on by Microsoft Employee

Hello all!

I have been struggling with this for a while, I hope someone can help out.
I have a situation where I have a Power Query / dataset 'dataSet', that can be refreshed with monthly new data. Part of this data set is:

 

Ref numberOwner

100

Jane
101Peter
102Frank
103Jane
104Frank
105Frank

 

Then inside a separate worksheet, I have manually entered the following 'static' additional information:

 

NameDepartment
FrankFinance
JaneSales
PeterFinance

 

I would love for a Power Query method to add a custom column in the existing query, that looks at the name and fills the custom column with the corresponding department. It should then look something like this:

 

Ref numberOwnerDepartment

100

JaneSales
101PeterFinance
102FrankFinance
103JaneSales
104FrankFinance
105FrankFinance

 

In normal excel terms I'd use VLookup. Could anyone help me how to do this using M formula language?

 

Many thanks in advance!

    Hi Syndicate,

    Thanks, I've tried it but it didn't quite work yet. I filled in what I believe is the table names, which I made as connection only queries:
    NewStep = Table.AddColumn(#"Replaced Value","Department",each #"Name vs Dept"{[Unique names=[Unique names]]}?[Department]?)

    "'Replaced Value" = the query where the new column should come with the data present of the first table in my original post

    "Name vs Dept" = the connection query containing the columns "Unique names" and "Department".

     

    Is it right to make this table I have on the different worksheet into a query in order to use it?

    Thanks again!
