The CWT Application has no support for cancelling an ongoing debit.
The extpu_OPP.dll external pay unit has a special implementation for cancelling an ongoing debit. It is based on Click-function in the UI.
There are two ways to abort a started debit.
| ● | Timeout |
| ● | Reject button. |
The reject button must have the click function: OnExternalPayUnitQuestionAnswer and KeyValue -1.
<TFT:Button MxStyle="{RejectButtonInputStyle}" KeyValue="-1" Click="OnExternalPayUnitQuestionAnswer" />
A Timeout event shall have the Click function: OnExternalPayUnitQuestionAnswer
TimeoutEvent="OnExternalPayUnitQuestionAnswer"
