using Business Objects crystal reports Release XI 2?

since i have no experience of this product but learning,I am wondering if anyone knows how to add a table to an existing "Database Fields" in crystal reports?
I dont know how the previous guy managed so I can't ask him as he is no longer here.
Currently the development server/SQL Server is stored on a different computer here locally. Obviously when this product will ship, it will look on the local box for the SQL Server, since this is where the database is stored on the live site in addition to the fact that the other Database fields (tables) are pointing to (the local)

any ideas?
