To remove properties in all tables from exposure as columns
Right-click on any row in the Tables table and then select the Clear Exposed Properties for All Tables command from the popup menu that is displayed.
All properties in all tables in the RPS mapping are then removed from inclusion as columns in the relational database tables; that is, each check box in the Features pane for a selected table is unchecked, indicating that no JADE properties will be replicated as columns in the mapped relational database tables.
