@Martin Salas I have accomplished similar using Standard: Type = SO Main Line = False Shipping Line = False Tax Line = False Summary: Sum, Formula (Numeric), is 1, case when({item.name}='Item A' OR {item.name}='Item B') then 1 else 0 end Now use Group for Transaction Name and Transaction Number in the output column. You can also use this same formula in the Results so that you can view what's going on.
