Content (required):

We are getting the error message when we attempt to reverse a receipt. We have unapplied the receipt, but we still get the same message. The receipt needs to be reversed in July, the receipt was applied to an invoice on 1 August in error. The users insist that this is a new error and that they have done the same task many times under the same circumstances previously. Would anyone know what the process or change we need to make in order for the users to perform these transactions
