Power Query - delete old date versions

Hi,

I will like to keep the last data version of data for each date in the table using "edit queries", deleting oldest versions. In the below table I will like to keep the biggest version number for each date: for May 5 version 2, for May 6 version 3.

How can I do this in M?

Hi @Aleph18 ,

 

you must create a subquery and group the data by date and maximum version. You can then merge the subquery with base data with an inner join

 

Check this.
