Which action is necessary if a transaction was performed on a different day and needs to be adjusted?

The necessary action when a transaction has been performed on a different day and needs to be adjusted is to scan the membership card and use the adjustment key. This process is crucial because it allows the system to correctly identify the original transaction while ensuring that any adjustments are properly documented and linked to the correct membership account.

Using the adjustment key is essential as it activates the appropriate functions within the point-of-sale system that are required to rectify the details of the transaction, such as the date, price changes, or item returns. This maintains accurate records and helps prevent discrepancies in the system, which could lead to accounting errors or customer dissatisfaction.

Additionally, by scanning the membership card, you ensure that the appropriate member is associated with the transaction, facilitating a smoother process for both the employee and the customer. This action not only aligns with proper transaction handling but also follows company protocols to protect against fraud or unauthorized changes to sales data.
