Possible Causes

Solutions

A transaction has an incorrect or invalid Returned Authorization Characteristics Indicator (ACI).

This often occurs in VT1TP05/A5 applications as a result of the first transaction in the batch being a credit or offline. The first transaction cannot be a credit or offline.

1. Delete the transaction that caused the RB.
2. Offline the corrected transaction and re-transmit.

If it is CPS software:

• Delete the batch, run a purchase, or auth only to force terminal to dial Auth Center.
• Offline the remaining sales.
• Run totals and re-transmit.

The Track Type in MMS and the terminal do not match.

1. Correct MMS and Master Reset & Full Download the terminal.
2. Run a sale and a void, or do an auth only, then offline sales, run totals, and transmit.

2. Offline the corrected transaction and re-transmit.
