Payables Open Interface Import Process Import No data

Greetings

We are trying to create invoices through *SQL Loader Program. We populate correctly interface tables (AP_INVOICES_INTERFACE and AP_INVOICE_LINES_INTERFACE) and I can check them by query DB but when I run Payables Open Interface Import no data is imported nor errors are marked in the output report.

Example File  Header

Example File Lines

The SOURCE we put a created lookup "Imported Invoices" and in the report program we run it for "Imported Invoices" as well, with a Batch that is already created in AP.

Would appretiate a lot your help, do we need to do a previous step first for running the program? We already have interface tables populated (both header and lines interface)
