How to Upload Logged Vouchers

We are trying to upload logged Voucher, so that we can subsequently 3-way match to PO.

I've seen post regarding voucher match after voucher creation by batch processing - in the F0411 table, the RP3 field is not populated with a P value (so JDE will recognize it as reliminary/logged voucher). We attempted and discovered the same. We were able to change RP3 on back end, and then voucher was available and matched perfectly!!

Oracle says that Multi-voucher, single supplier (P041017) won't work for Logged vouchers.

Are there any other solutions to import vouchers ?

we're running E1 - 8.12

thanks!
