Removing Duplicates with Power Query

Matt Allington wants to remove duplicate records while retaining the last version of the record using Power Query:

Today I was helping a customer with a problem that seemed quite simple on the surface.  She had a data table containing historical customer sales orders (each customer has many orders on different dates).  The objective was to filter this table in Power Query and just load one record for each customer – the one that was the last order date.  To illustrate the problem more clearly, I have adapted the scenario using the Adventure Works database.

Click through for the demo, and also read the comments as there are a lot of interesting attempts to solve the problem there as well.
