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