In order to refund or return a pass, an operator first adds the pass item to the sale, sets the quantity to -1 and enters the pass number of the pass being returned. The pass number entered must be from a pass that matches the DCI of the pass item currently being returned. For instance, a Child Membership pass may not be used to validate the return of an Adult Membership pass item. When a pass number from a matching DCI is entered for the pass refund/return, the pass number entered to validate the return is voided. The voided by field is populated with the operator logged into Sales at the time of the return and the voided for field is populated with the word returned.
