How to create a payment batch in AP Payment Manager, that creates a file possible to upload into a F

In our French unit, we would like to use the AP Payment Manager in order to do batch payments instead of single.

The output of the payment should be a file (txt or xml, I assume) that we should be able to upload to the bank in order to execute the payments to each supplier.

Any ideas/proposals of how to do that and what settings/formats to use.

Have tried around without success...

Thanks!
