Re: Merge problems - incorrect expand

Hi, try adding an Index column after the "Group by". This seems to work for me.

Re: Merge problems - incorrect expand

I got a satisfactory result after including a Table.Buffer() before the SORT().

I had a similar issue. What fixed it for me was adding in a dummy "replace values" step before I expanded the merged table out.

This has also been a huge paint point for me.  

 

I think the Table.Buffer trick has worked but it really slows down performance for me.  

 

I may end up doing this in an excel and just pasting the results back into Power BI and moving forward from there.  Very disappointing.

Re: Merge problems - incorrect expand

You need to add Table.Buffer to the last step in the Query you are going to merge later into another Query (the query where the expend goes wrong). Same as how you need to Table.Buffer if you want to remove duplicates and always keep the 1st item after a sort.
