I'm using a stored procedure to populate a crystal report, But I get repeatative(duplicated) information on my report- something like 66 pages instead of atleast 2. I want to produce a transactions statement for a particular user, using the crystal report, with the stored procedure getting data from multiple tables, accepting as a parameter the name of a particular client(user). Am I using the crystal report for good purpose or may be the stored procedure isn't just a way of doing it? :confused:
