Can we disable the field "Tax control amount" in supplier portal when supplier create invoice? We found that the field confuse supplier that some suppliers(not 1 supplier, many suppliers got confuse...) input the invoice amount (before tax amount) in this "Tax control amount" field.

Since we applied tax % to the invoice, we don't require supplier to input the exact tax amount in AP invoice.

Also, if the supplier match PO line USD100 , and input tax control amount USD100, system will still pass the 3-way match and proceed to payment, and the payment amount will become USD200... which is causing issue of over-payment.
