You chose No when you received one time message "Do you want to update the item with the new cost?" and you put a check mark on the “Do not display this message in the future” box. As such, changing the price of the item on the Check or Bill doesn’t update the information on the item list window.
Note: Because this change occurs on the My Preferences tab, it is specific to the user logged in. If you have multiple users, you will need to log in as each user complete these steps.
Note: You may need to make inventory adjustments, if items were bought and sold with an incorrect purchase price.
