Forgive my ignorance as I know next to nothing about accounting. My situation is this: we have a process where we use Auto Invoice (along with other programs) to import external data into our 11.5.9 (I know, I know!) E-Biz environment. Some of this data is what they call bulk payments - multiple (somewhat related, somewhat unrelated) payments on a single invoice for a single vendor. The first time this type of invoice comes through it processes correctly on the Financials side. If another one comes through from the same vendor with the same invoice, the record is rejected due to duplicate invoice number. It seems to me the way to handle this situation is with line items/numbers but I do not see a place to store that information in the ap_invoices_interface table. Is there where a flexfield makes sense? In other words, use a descriptive flexfield to store each individual line number on the invoice. And, if that's the case, is there a way to make the Auto Invoice aware of that flexfield? I am not looking for a technical answer here, just if I am on the right path to solving this issue. Any/all comments/suggestions/stock tips welcome. Thanks in advance, -joe
