'Product Type' in Tax determining factor refers to 'Line type' in PO?

Hi all,

eBtax rule based on product type works fine for AP manual invoices, but does not work as expected for Purchase orders.

Based on Product type , appropriate VAT rate code is defaulted in manual AP invoices, but no VAT rate code is defaulted for Purchase orders.

'Product Type' in Tax determining factor refers to 'Product type' field in AP invoice form, but is it also related to 'Line type' in PO?

Thank you,

Elena
