Hi! 

We have e-invoice with PO having different tax codes. We have checked the check box “Affect line Postings” on External Supplier invoices line to see if posting lines are created per tax codes. As you can see in picture from Posting Proposal, the posting lines for tax code 1 and 0 were ok but the line with tax code L10 has got tax code 1.  The purchase order lines looks correct. Does anyone know how we can do so the tax code from PO lines should follow when posting lines is created automatically? 

We are using App9 and PO matching on header level.
