Power Query | How to remove (older) duplicate records

Hi once again,

 

How do you recommend to remove an older version of a record. I plan to use the file created date as the time stamp to tell which record is newer.

 

Here's a dummy data:

 

ColorShapeMaterialStored
RedCircleWood7/2/2017
RedCircleMetal7/2/2017
RedCircleWood7/1/2017
YellowCircleWood7/4/2017

 

So the plan is to remove record #3 because it is an older version of record #1, the "Store" column should tell when it was stored.

In power query (get data) sort by the date column descending. Then select all columns except date and select remove rows\remove duplicates.

I will not give you bad advice, even if you unknowingly ask for it.

I see, so it does have that behavior. thanks @MattAllington
