1. Say my data is required from two Tables, Tran and Products, where Products gives the description
2. I have set up a 'Dummy' business Object which will be used for ALL my Joined Tables (Query ? Can I do this with just one Dummy Business Object for ALL my lists)
3. I have a Stored Proccdure which Joins the Tables Tran and Products
4. I specify the Dummy Business Object as the BusinessObjectType  in the PopulationDataSourceSettings 9With a different Stored procedure depending on the  Tables)
(When entering the Columns, I type in the column names as they will not be in the buisness Object when it is initially set up)
5. My main concern is that I am using in effect  a Multi Table Business Object (whereas when Business Objects are being set up they are limited to One Table only) and wonder if this will cause any problems in SF
