    Hi, apoje 

     

    Try this, for 100,000 lines please wait about 20 seconds to upload to excel.

    let
    Source = Excel.CurrentWorkbook(){[Name="Table25"]}[Content],
    Custom1 = Table.FromRecords(List.Transform(Table.ToRecords(Source),each if [Variation.Number]="0527" then _&[Variation.Number=1999]&[Quantity=[Quantity]*10] else _))
in
    Custom1

This one is faster than the Record one.

let
    Source = Excel.CurrentWorkbook(){[Name="dataset"]}[Content],

in
    Table.FromRows(res,{"Order.ID","Variation.Number","Quantity"})
