Supplier Site Import Process Not Populating The Tax Registration Number (VAT Registration Number) - Oracle fusion Cloud

Supplier Site FBDI has two columns VAT Code and Tax Registration Number. These two fields are not imported through the Supplier Site FBDI import process. 

Supplier Site gets created successfully, however the VAT code and Tax Registration numbers are not getting populated anywhere. 

Also notice that in the interface table, these two columns are not getting populated with the FBDI data values( due to the FILLER options while loading into the interface tables - POZ_SUPPLIER_SITES_INT, which is getting skipped). Please see screenshot provided below.

Oracle has confirmed the same. Both Vat Code and Tax Registration Number are not supported functionality via the Supplier Site import process.  Please see below the Doc ID provided.
