Warranty in GP

Hi,

Is there a way to automate monthly warranty accruals in GP?

For example, at the time of sales warranty was accrued with debit of warrranty expenss and  offset in current and non-current liablitiies. Every month we need to reclass non-current liablity to current liablity for 1 month... Is there a way to do it automaticlay - something like deprciation in Fixed asset module?

Regards,

David
