Current D365 config requires the user to click the "Tiered charges" button in order to trigger the Tiered automatic charge calculation on a PO. If the user does not click "Tiered charges" the charge is not applied to the Purchase Order. If the user makes an update to the PO but does not click "Tiered charges" any auto charge that has been previously applied is not recalculated.

This behaviour is not 'automatic' and it would be great if it was.

We are unable to implement this functionality unless it is fully automatic as the users cannot reasonably be expected to know which Vendors have tiered auto charges and there may be charge errors if not refreshed after changes are made.

The Tiered automatic charge calculation does not need to be triggered on every change, it could be triggered when the user clicks Save, Submit and/or Confirm.
