Tax Classification Code not defaulting from Supplier /Site on the IDR PO Matched Invoice

Summary:

The 'Supplier' holds a Tax Classification Code, and when a PO (without tax) is matched to an AP Invoice through the UI, the Tax Classification Code defaults from the 'Supplier', and the tax is calculated correctly. However, when the same PO is processed via IDR (Intelligent Document recog), the 'Tax Classification Code' is not defaulted on the AP Invoice. How to address this issue? please suggest

COTO: Regime Determination Set: STCC, and 'Enforce tax from reference document' unchecked. There is no Tax on the PO and Idea is to calculate Tax on the Invoice only.
