Query Builder - How to use compound (union, unionAll)?

[grocha]

I am trying to create a simple report which shows attributes from a specific type and also attributes from one of his child type (sub-type). I could find one article at PTC with an example of unionAll but I could not replicate it.

It shows zero results, I've played a lot with it and it is driving me crazy...

See attached my report.

Any help will be greatly appreciated
