Not able to import self service receipts

Summary:

We are trying to import Self Service Receipts for expense items. We are repeatedly getting error of invalid "VENDOR_SITE_CODE". We verified that the Supplier site code is valid and active. Also, we are able to receive it from the Fusion UI without any problem.

We also tried to delete supplier, supplier site from the import (since we are providing PO data and PO has supplier/supplier site details) we are getting error that supplier / supplier site is not provided.

Any hints will be appreciated.
