On the Override Instance screen, you start a series of sub tasks to override token processor settings specifically for this connection.
Note:
Any changes to the base token processor instance are propagated to a connection provided the same changes are not overridden for the connection.
If you are editing a currently mapped token processor instance, click Override Instance Settings to reconfigure any overridden settings for this connection. You may also remove all overridden settings on a per-screen basis by clearing the Override check box near the top of the screen.
