Thanks a lot Rogerio. The document helped. I was able to get the Merged queries with 1 to N relationship to work. The biggest tip was the 'Show rows with Empty Dimension Values'
The other thing that I noticed was that for my report, even if a dimension is un-merged , it does let me drag it onto the table, as long as it's from the many side of the query. I didn't have to create a Detail variable.
If you send me your personal email address, I can see if I can send you some data in an excel sheet...
