Import AP Invoices - WFAPPROVAL_STATUS

Hello,
in the table ap.ap_invoices_all the field WFAPPROVAL_STATUS exists.

I have to import invoices via the AP Interface and the WFAPPROVAL_STATUS should be "Not Required" for all imported invoices.
Where can I set this field at the import? Is there an option to set it at the import into the AP Interface or does it have to be set at the import from interface into the EBS?

Thanks & Kind regards
Stefanie
