It should warn if you're trying to create a duplicate. To test: 1) Turn on AcqWarnOnDuplicateInvoice. 2) Try to create an invoice that duplicates an invoice number you are already using exactly once. 3) Note that you get a warning after applying this patch. -- You are receiving this mail because: You are the assignee for the bug.
