Sage 50 US

I am trying to get a csv file to import into the payroll using Sage 50 Accounting, and I was wondering if it will still work if I leave the un-required fields--such as, Employee First Name, Check Number, etc--blank and filled in the required fields? …

Can Sage-50 US create a NACHA file for export to a Bank? I've looked at Help - but nothing comes up with a NACHA search
