Match values in comma seperated column

Hello,
 
I have a question regarding comma seperated values.
 
The example data consists out of three columns: "Product_ID" (unique identifier), "Parts_Used" (comma sperated list) and "Price" (simple number).
 
As you can see in the "Matching"-table I'd like to be able to change the part names by updating the corresponding names within this table. The problem is that I want to keep the comma seperated form of the "Parts_Used" column.
 
Is this somehow possible?

 

Here you can find the sample file:

Kind regards

    Hi Anonymous , 

    You could try to use M code to achieve this goal. You could refer to my sample for details.

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ZY9LCoAwDAWvIll30XzVW7gvRbyCeH+MrSmIu0dnmpeUAggJtuO89oxp6oEjmDMkFqipAA2RgmuExZl72kT+TcT4gU8bslATZYhrDJr9SYU718FHkX0b39UsRMpRFDfg2m5Qg1pv", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Product_ID = _t, Parts_Used = _t, Price = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Product_ID", Int64.Type}, {"Parts_Used", type text}, {"Price", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each Text.Split([Parts_Used], ",")),
    #"Expanded Custom" = Table.ExpandListColumn(#"Added Custom", "Custom"),
    #"Replaced Value" = Table.ReplaceValue(#"Expanded Custom"," ","",Replacer.ReplaceText,{"Custom"}),
    #"Merged Queries" = Table.NestedJoin(#"Replaced Value", {"Custom"}, #"Table (2)", {"Part_Old"}, "Table (2)", JoinKind.LeftOuter),
    #"Expanded Table (2)" = Table.ExpandTableColumn(#"Merged Queries", "Table (2)", {"Part_New"}, {"Part_New"}),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded Table (2)",{"Parts_Used", "Custom"}),
    #"Grouped Rows" = Table.Group(#"Removed Columns", {"Product_ID"}, {{"Part_new", each Text.Combine([Part_New], ","), type text}, {"Price", each List.Average([Price]), type number}})
in
    #"Grouped Rows"

    Hi Anonymous , 

    It seems that you upload wrong sample, I didn't see "Product_ID" (unique identifier), "Parts_Used" (comma sperated list) and "Price" (simple number) in your link. So if possible could you please inform me more detailed information(such as your expected output and your sample data)? Then I will help you more correctly.

    Please do mask sensitive data before uploading.

    Thanks for your understanding and support.
    Best Regards,
    Zoe Zhi
