Hello Experts!

We have an inquiry if it is possible to edit the withholding tax code and recalculate tax in the invoice after validation? We have found in existing Oracle documentations that for business units with tax calculation point = invoice that "If you select this option, Oracle Fusion Tax calculates withholding only once. If you adjust an invoice after it was validated, you must adjust the withholding tax manually and enable the Allow manual withholding option." Considering that we have tried to edit some parts of the invoice and still no luck in adding/updating the withholding tax lines.
