6.7.6.4 Clear Reversal
Note
If an authorization request is sent to host, but there is no response
received, the terminal will try to reverse that transaction to avoid
mistake. But sometimes it may happen that the reversal can never
success, this will result in that no more transaction can be processed.
To avoid this situation, you can clear the reversal flag in this menu, so
that the terminal will not try the reversal anymore.
Note that the original transaction may already be approved in host, so
the total transactions may not match while Batch Close.
