Deallocate a previously posted allocation
It easy to allocate a customer payment against the incorrect transaction, but until recently it has been more time consuming to undo the mistake. Opera 3 Sales & Purchase ledgers now include a Rectify Allocation feature which is located on the Action button of a customer/supplier account screen.
Simply follow the on screen prompts to choose the previous allocation and tell Opera 3 whether you need the allocation link broken for reposting or whether you would like to remove the whole transaction (bounced cheque etc). For audit purposes, Opera 3 requires you to enter an explanation why the deallocation took place.
