4.10 How to process a Pre-Authorisation Partial Cancel.

A pre-authorisation partial cancel is used to partially cancel a pre-authorisation, where
the expected value of the final transaction is lower than the initial pre-authorised
amount. The expiry date of the original pre-authorisation transaction is not changed.

Start by initiating the transaction via the POS interface.
The POS will then prompt for the ROC, of the original
pre-authorisation, to be entered.
>
Enter the ROC number on the POS.
Wait for the POS "Scanning Batch" message to complete.
This will occur when the ROC lookup completes.
If the ROC cannot be found, the terminal will prompt for the
ROC to be re-entered into the POS. If this secondary ROC
entry is not successful then the lookup can be performed
using the Auth Number.
If the lookup is successful then the pre-authorised details
will be shown (last four digits of card number, amount,
authorisation number).
Confirm via the POS whether the authorisation details shown
are correct
