Cancellation of SO- Packing Slip AX 2012

Hi,

When I’m trying to cancel the packing slip for a sales order- AX 2012, I’m getting an error "Voucher number must be filled in; An error occurred during update ". Can anyone help me out with this.

Thanks

AR Parameter> Number sequences tab

set the number sequence for “Packingslip correction voucher”
