When loading a BAI file into IFS, how does IFS distinguish customer invoices from the remitter name in detail record 6, positions 51 - 80( using BAI 80 )?  These positions, according to the functional specifications, list these positions as either invoice numbers of a 15 character remitter name and on 9 digit invoice number.  How does IFS distinguish and invoice number from a remitter name?  In testing we had remitter names showing up as invoices to match.

We are using APPS 9
