We have first party Registration at IO Level. However while booking of AP Invoices, we don't see Tax getting calculated after Validation. It is only after we go to India Tax Details Screen, there we see above warning message. When we click "Continue" then the screen is close and only after that we see Tax Information (Misc Lines) on the AP Invoice.
