OBN/CMK: Payables Invoice Tax Line rejected with 'Insufficient tax information'

Summary:

We are receiving payables invoice message (payload) from our supplier through Oracle Business Network (OBN) / Collaboration Messing Framework (CMK). The invoices are getting rejected in Payables interface with 'Insufficient tax information' error. We know the primary reason is we did not implement Fusion tax for our business. We add the tax amount to our Invoice line amount for all our suppliers while creating invoice. Meaning, there is no tax setup to calculate the tax for payables invoices.

We are not licensed for Fusion Tax. We expected to import the tax line as it is sent from the supplier without any calculation in Invoice workbench.
