Electronic payment in AX 2009

Hi

One of customer makes electronic payment to its vendors. For that he post normal entries in the AX (dr. vendor cr. Bank) and fill up ONE FORM given by the bank manually and send it to Bank for processing. Bank further transfer fund to vendor accounts.

Now He just wants this FORM to fill up automatically while preparing payment.

How do achive this using method of payment as electronic payment. I tried in AX method of payment but the file it create does not open.

Can anyone help me regarding this.

Thanks & Regards
