We have the company parameter ‘ Inherit Authorizer(s) from purchase’ checked ( Company > Invoice Tab > Supplier Invoice Workflow tab).

When I create a manual supplier invoice and match to a PO it does bring up the authorizer from the PO across to the posting proposal. 

However, I have noticed if the invoice comes through the OCR ( we are using ABBY) the authorizer does not come across and we always have to manually add the authorizer.

Could this be caused by a setup that we are missing ?
