I am building a report inside one report the inner report SQL depends on what the outter report SQL is returning. I read that the only way to use variables in the SQL is declaring the variables as parameters. The problem with it is that I need to modify those paramenters in the report. How I can do that? or How i can link the Inner SQL with the outer SQL? Confucius once said, "I hear and I forget. I see and I remember. I do and I understand."
