Hi Guy,

Since this is for lookup purpose and not using for updates I would just create your stored procedure to return what you want and then in your business object you can return a DataSet rather than an entity list and calling that stored procedure. This way you join whatever you want from your tables.

The best example I can think of is a customer with invoices. (That's not what I'm really working with but this simple example will do.)
