Error helper behavior
Used to handle the B608 ASK FOR CARD CLEAR TO CONTINUE
prompt.
SA
There are two reasons for getting this message. One is a reminder to
get the customer's card when the total key is pressed. The other is
when a coupon is entered that is limited to preferred customers. If
the error handling mode is automatic, the error helper clears the
error. If the prompt was generated in response to a coupon that is
limited to preferred customers, the error helper throws an exception.
If the error handling mode is default, the error helper waits for the
operator to clear the error. If the prompt was generated in response
to a coupon that is limited to preferred customers, the error helper
throws an exception.
ACEErrorHelperB676
SAErrorHelperB676
ACE, SA
Used to handle the B676 ACTIVE SUSPENDS, CLEAR OR
CONTINUE prompt. If the error handling mode is automatic, the
error helper clears the error to allow the signoff. If the error handling
mode is default, the error helper waits for the operator to clear the
error to allow the signoff.
AcceptOrVoidTender
Used to handle the ENTER TO ACCEPT OR CLEAR TO VOID
tender prompt in GSA. If the error handler is in automatic mode, the
error helper sends the ENTER key to accept the tender. If the error
handler is in default mode, the error helper waits for the operator to
handle the prompt. If the operator clears the tender, an exception is
thrown.
GSA
AccountNumberErrorHelper
GSA: Used to handle GSA state 51. In automatic mode, the error
helper retrieves the account number from the tender identifier and
sends it. If none is found, an exception is thrown. In manual mode,
the AEF waits for the operator to enter an account number.
GSA, SA
SA: Used to handle B048 ACCOUNT NUMBER NEEDED guidance
message.
In automatic mode, this is a fatal error, the guidance is cleared, and
an exception is thrown. In manual mode, the AEF waits for the
operator to enter an account number.
AgeRestrictedHelper
ACE: Used to handle date of birth prompt for age restricted items.
ACE, GSA, SA
GSA: Used to handle A399 AGE RESTRICTED ITEM guidance
message.
SA: Used to handle B107 AGE CHECK NEEDED guidance.
In automatic mode, if the Automation Provider is configured to
handle age restricted items automatically, a hard coded date of birth
is entered to satisfy the age prompt. If the Automation Provider is
not configured to automatically handle age restricted items, or the
error handling mode is default an exception is thrown.
AppDefaultErrorHelper
This is the error helper used whenever an error key cannot be
located in apperror.properties. An exception is always thrown. This
usually indicates that an error helper should be configured.
ACE, GSA, SA
AuthorizationCodeErrorHelper
Used to handle the ENTER AUTHORIZATION CODE prompt. In
either automatic or default error handling modes, the error helper
uses the authorization code from the tender identifier as input for a
key sequence to satisfy the prompt.
ACE
BaseDescriptor449ErrorHelper
This error helper might be used when the error handler encounters a
blank line on the operator display. The error helper waits for the line
display to change.
GSA
