Invoice Interface

[turbo]

Hi all,
I use sql*loader to upload data from excel to Interface tables (AP_INVOICES_INTERFACE and AP_INVOICE_LINES_INTERFACE).
Then I run request Payables Open Interface Import. But no any record is imported.
Would you please help me?
- parameter Source: I choose Manual entry invoice. I think it's wrong. I don't know what do I choose?
- I don't have distribution set, so what field do I choose to record for account distribution

Thanks for advice!
