In IFS8 there is Tax Code per Account validation on invoices matched with PO and without PO.

In IFS10 this validation does not exist. This means that a certain account that is not parameterized in the Tax Code per Account screen can be used incorrectly. However, if you manually enter an invoice (without a PO match) the system will make the correct validation.

Can you clarify if for invoices with match to PO the IFS10 does not perform this validation?
