Move Date after GroupBy

[Einomi]

Hello,

I have once again PDF invoices coming through, unfortunately even if they appear the same, in Power Qeury they look different

I will paste the code for your convenience as @BA_Pete taught me (thanks for that)

I have 12 columns.

The first one is Source.Name and I want to keep it as is

The next 11 columns need a bit tranformation, what I need is 

Col 1 : Item Code

Col 2 : Qty

Col 6 : Special Offer

Col 7 : Price

Col 8 : %

Col 9 : Disc

Col 10 : VAT

Col 11 : Subtotal

Everything between Col 3 and Col 5 will be merge and will be the description. Eventually we will end un with less columns that 11

Thanks for your time and for your help (if possible to tell me your approach so that I can learn also)

You can read the step names and it should give you a good idea of the approach.  I removed the column names/types from the Group function because it will mess up the Table Expand when the column names are not properly defined. I combined Special Offer with the description.  You can move it to a separate column or add a custom column with if Text.Contains([Description], "Special Offer") then "something" else "something else"
