Manual cheques must be numbered manually. Printed cheques may be numbered entirely manually also. Earnings, deductions and the cheque entry must all be assigned the same cheque number during entry. Automatic cheque numbering offers flexibility without interfering with other cheque numbering. To allow automatic and manual numbering for the same bank account, the Account entry carries the next cheque number used for automatic numbering. Automatic cheque numbering offers this as the starting number for a run. It can be overridden at run time. All the unnumbered cheques for the selected period are then numbered. Cheque numbering is not a repeatable exercise for a pay period.
