How to set up an AP payment file format

Hi All,

In AX2012.

My client wants to set up an ACH AP file format that will generate both a payment advice and a control list.

I selected the export format NACHA (US). When I generate a payment from the AP payment journal I get the following message:

Number of transactions: 0

Total amount: 0.00 USD.

What set ups am I missing?

Thank you in advance,

Michelle
