Can i create the report by assigning more than one table

I'm new for LN Programming... I have created a basic report by using a single table.... But right now, I need to develop a report by using two table with different types of columns.... So is it possible to create a report by using more than one baan tables... If it is possible one, please let me know how to do that...?

Thanks in advance,
