Receiving XML invoices via OBN & correcting import errors on tax lines

Content

Hello experts, we are on Fusion 21A

We receive electronic invoices from three suppliers in XML format coming across the Oracle Business Network.

All of these invoices land in the Correct Import Errors queue with line rejections on the tax lines.  The nature of the rejection is 'Insufficient Tax Information'.

We find in our case, all we have to do is add a Tax Classification = 'STD' on the tax line and it then goes through to AP.

Is there a way we can default this?  Is there a mapping perhaps?
