To remove special columns for a selected table
Right-click on the table row in the Tables table and then select the Clear Exposed Special Columns for Selected Table command from the popup menu that is displayed.
All special columns in the selected table in the RPS mapping are then removed from inclusion in the relational database table; that is, each check box in the Features pane for that table is unchecked, indicating that no _operation, _tranid, _timestamp, and _edition special columns in the class will be replicated as columns in the mapped relational database table.
Historical tables will still include the required _operation and _timestamp special columns.
