Microsoft Power Query - Grouping on single and multiple columns

Nice, thanks!

Thank you so much! I was getting frustrated with trying to get all the other columns back. There are other tips online (like merging the grouped table with the same table before it was grouped) that just were not working!

Exactly what I want. Thanks

Thank you for this useful instruction I have been applying in my daily work for
about 3 weeks.

Great ! Thanks !
