There are two types of override, local override and remote override.
All procedures are performed in one teller term as shown in the following figure.
All procedures are performed in two terms. One is the teller term, and the other is the supervisor's term as shown in the following figure.
If a transaction needs override and the teller has selected the remote override route, the override request is sent to the supervisor and the current working area on the teller's side is locked. The supervisor can access the transaction screen in his or her local term to approve or reject the request. The final result can be read in the teller term. The teller can switch to another transaction in the teller term when waiting for the approval.
The following figure displays the deployment topology of BTT Override. For details about the procedures on the teller side, the supervisor side, and the server side. Refer to the tasks section.
