I feel like I'm missing something simple but is there no way to get 3-2 A/R Receivable Invoices to automatically prefill the invoice number?  When we create an invoice we can enter all the info but it won't let us save the invoice until the invoice number field is filled in and it doesn't seem there is any way to have the program remember the last number and add incrementally? Right now we have to look up the last invoice created and then enter the new invoice number manually.  Is there a setting somewhere so the program does it auto?

The part that confuses me is that when we create invoices through 3-7 Progress Billing it does seem to create the invoice numbers automatically when it generates the invoices in the background.  I don't understand why it wouldn't through 3-2?
