Table grouping by passing columns name from anther table

[jlauyfc]

Hi guys

I'm trying to group my product export csv file by a few keys and an aggregatedColumns "Variant SKU". I got errors on the aggregatedColumns column that added. I spent a few hours searching for a solution on the web, and most suggest using Record.Field to get the column data from passing a column name. Please help.

excel file: Product List sample.xlsm 

source csv: products_export_1.csv 

expected result: expecting result.csv 

Problematic code: (in table "Product List Grouped SKUs")

= Table.Group(#"Added Custom", Table.Column(#"Product List Header Group Key", "Key"), {{"Variant SKUs", each Text.Combine(Record.Field(Record.FromTable(#"Product List Header Group Aggregate"), "Aggregate Column"), ", ")}})

Table "Product List Header Group Aggregate":

Table "Product List Header Group Key"

Error: 

Error Detail 1: (this error cannot be reproduced in the sample)

Expression.Error: The key didn't match any rows in the table.
Details:
Key=
Title= xxxxx

Body (HTML)=xxxxx

....

..

Error Detail2:

Expression.Error: The field 'Name' of the record wasn't found.
Details:
Column #=Column18
Aggregate Column=Variant SKU

Please help😔

Hi @jlauyfc, i do not understand the purpose but I've solved your error:
BTW: you should read about functions before you use them, the issue was with Record.FromTable - for this function you have to specify Name and Value.

= Table.Group(#"Added Custom", Table.Column(#"Product List Header Group Key", "Key"), {{"Variant SKUs", each Text.Combine(#"Product List Header Group Aggregate"[Aggregate Column], ",")}})

I am using power query in excel but not "Power BI Desktop", so what file should I share?

That is easy!  Share any related source files and your work-in-progress Excel (.xlsx) file in the same manner as you would if it were a Power BI Desktop File.

I've uploaded the excel file, source csv and the expected result sample files.

You need to make those files accessible.

fixed. Thanks.

I can't help you with Error #1 since, as you wrote, the sample does not reproduce it.

For Error #2,  try this for your #"Grouped Rows" step

    #"Grouped Rows" = Table.Group(#"Added Custom", Table.Column(#"Product List Header Group Key", "Key"), {
        {"Variant SKUs", 
    each Text.Combine(Table.Column(_, #"Product List Header Group Aggregate"[Aggregate Column]{0}),", ")}})

Results
