ER 5400M Service key

service would allow you to cancel a sale from a clerk - assuming you have a cancel key - but it would show as a total on the reports
simplest way is tot to ring it in - every other method leaves traces - cctv linked to the audit printer is the way forward.

Thanks Andy, appreciate your help.

My pleasure - not really been of much use tbh - but at least you know how to clear the service totals
