What is the process to void a previous transaction?

The process to void a previous transaction is correctly identified by using the adjustment key. This key allows supervisors and authorized personnel to make necessary changes or cancellations to a transaction in the system effectively. Utilizing the adjustment key ensures that all entries and system logs maintain their accuracy, allowing for appropriate recordkeeping and preventing confusion in inventory and sales data.

Re-entering the transaction number does not directly lead to voiding a transaction; it might instead bring up the original transaction details without altering or canceling it. Scanning the original receipt typically serves purposes related to returns or exchanges instead of voiding a transaction. Pressing the refund button can initiate the process for refunds but does not strictly void the original transaction, which is a separate action aimed at reversing the sale itself.
