Hi Mike,
As Jim has noted in his post, those tables are standalone SQL tables and not user-defined tables. Most Enprise tables tend to be standalone SQL tables and the DBDataSource object can't be used to read this type of data. You can use either a DataTable bound to a matrix or grid to query the table or use UserDataSources and populate these from a recordset. Since version 8.81, the DataTable option is typically the best option as it's faster.
Kind Regards,
Owen
