I am a newbie at this forum and I need some help . I am using Crystal reports from Maximizer. Crystal reports shows me the following message "failed to retrieve data from the database.The query and the views or function exceed the limit of 256 tables"  I want to add more tables in order to finish my job. I used 18 tables but I need more .  How can I do this?

I've never used maximizer. But if you're at the table limit then the only thing you could do is create views which consolidate multiple tables into a single 'virtual table'. If this isn't possible with Maximizer, then you can't add any more tables.
