Sometimes you may accidentally enter the same item number twice. Other times you actually want the same item to be shown as two or more separate line items. Depending on which edit mode you are operating in will determine how entrée handles the entry of a duplicate item.
Invoice edit mode
entrée will warn you that the item already exists on the invoice. The Duplicate Item message box will display "Item #99999 already appears on this invoice. Would you like to keep the new entry?". Click Yes to keep the new entry or No to abort the entry.
Standard Order edit mode
entrée will not allow you to have duplicate items in the customer's standard order file. The Duplicate Item message box will display "Item #99999 already appears on the customer's standard order.". Click OK to close the message box.
Credits edit mode
entrée does not check for duplicate items when the edit mode is set to Credits.
