Use the Adjust Unit Value button to change the unit value of the currently selected item while completing a refund transaction. Note that the unit value is applied to the selected item one time only and valid for just this transaction, i.e. this won't change the value for the item in the item inventory list. Thus, it is highly recommended to add some comments to the item description with the reasons for changing the unit value. Item Description:
Enter the full description and append the reason for changing the unit value.
Unit Value:
Adjust any unit value for the selected item. The values can not be adjusted for coupons in percentage.
