3578927 - Why does the VAT Registration ID not automatically pass into the Line Item of the Vendor Invoices?

While posting Vendor Invoices, the VAT registration ID is not automatically pass into the Line Item.

SAP S/4HANA Cloud Public Edition

In Customer Invoices the fields Reporting Country and VAT ID is automatically populated, because the EC Sales list needs these information.

Customer Invoices and Vendor Invoices behave differently when it comes to the population of document item (background table:BSEG) fields Reporting Country and VAT ID:
In Customer Invoices - and for foreign customers - these two fields are automatically populated from the source data.

Reason is that the EC sales list needs them.

In Vendor invoices there is no such automatic population.

This is the standard system design.
