Hi all

We are currently using the recurring funtion in Payables, as a result our Periods has to be set to 'Future ' to allow the recurring invoice to be create for periods that they would extend to.....Having set the periods to future users can still enter regular invoices in future period in error....Is there a setup to prevent invoices that entered in furure period to be paid in the current period...Example the current period is Apr-12, and invoices are intered in May-12 in error, if invoice was approved and validated..how can i prevent this invoices from being paid in the current
