We have a need for assigning a value for Tax group on every accounting line.

We can fix this, by putting the Tax group on the supplier, but this can only be done for a small amount of the suppliers. So, our users need to register the Tax code manually for the majority of the coding lines. But the problem is that many of our users forget to fill in the Tax group and the invoices then stops in the Post Control.

It would be a good feature to add a rule that prohibits the user so send the invoice further on before the Tax group is filled in on the accounting line. This would decrease the number of invoices that are stopped in the Final Control.
