On several occasions, an incorrect serial number has been recorded or a name is left off a transaction. When I find these errors, I need to the ability to go in a correct the mistake. Additionally, when a battery is warrantied, I need to remove the serial number associated with the person's record and put in the new serial, so that I can always see what serial number they have. Yes, I could just make a note in the customer account, but that doesn't correct the actual backend data, which means that when I run the serial number report, it's not accurate. Or if I run the Who Bought What Report, its not accurate. As the owner of the business, I need the authority and ability to correct the backend data when I find mistakes.
