Thank you Erick. I readed a lot of in the web and I still a litle lost. In summarizze, I need perform a join (sql join). For the moment, I evaluated the following alternatives:
1. Alias (first response). I think it doesn't solve the problem, because I understand this is usefull to union (sql union) of the results. So I dont found how can it help me. 2. Join Query. it is not a sql join because only show data for the first item and it only filters for the second item.So I discharded it. 3. Block join. I dont finish understand it (the functionality and where I need to configure). But I think it dont solve the needed because It define a paret/child relationship. Do you have some clue to investigate?
