Invoices not selected in the payment request

Hi,

i created a couple of invoices for a given supplier  and then ran the payment process for the  the supplier giving the payee name.

Strangely the invoices were not selected in the pament process request.

The log file of the concurrent program Auto Select (Payment Process Request Program) does not say anything.

No scheduled payments matched the invoice selection criteria

The  schedules  payment date  is today,has someone any clue of what might be wrong.

Thanks

Ashish
