Dataflow Merge and Aggregate
Hello, I have merge two tables together in a datafow. When I try to expand the resulting column I do not get the option to 'Aggregate' like I would do in desktop. I've tried adding the below as a custom step in the dataflow
= Table.AggregateTableColumn(#"Merged queries 1", "Planned Dates", {{"DOCUMENT FILE NAME", List.NonNullCount, "Count of DOCUMENT FILE NAME"}})
But get this message "Expression.Error: The name 'Merged queries 1' wasn't recognized. Make sure it's spelled correctly."
What am i doing wrong? Many thanks
Hi dm1904
I can make it work on Power Query Web part.
Please check if #"Merged queries 1" is the last step name in your scenario.
Or you could take the following as a workaround:
1. merge queries,
2. expand the value from another table
3. groupby the table as below
