One-time Vendor Invoices

Hello,

I need to import One-time vendor Invoices in S4C.

The system allows to create One-time vendor Invoices manually via the app 'Create Supplier Invoice - Advanced', but I would like to know if there is a possibility to import these Invoices.

In the template provided in the app 'Import Supplier Invoice', I can not find the following fields: vendor name, address, VAT number (needed for VAT return in Spain).

Thanks for your help.

Regards,

Anaïs
