AP Invoice Discounts. Can you 'back out' an invoice line?

I am aware that discounts are not applied to misc charges attached to lines and the invoice header.

Accounting would like to be able to remove a line from the discount calculation from when the discounts are calculated for the AP invoice.

Reason being tariffs are being charged to us on an invoice along with the materials we ordered. We enter these as miscellaneous lines on the invoice so the invoice has a combination of received lines and miscellaneous lines. The supplier does not want to give us a discount on the tariff charges. All fields related to tariffs on APInvDtl appear to be zero so is there a way to discount misc lines from a tariff calculation.

If Tariffs is charged with materials which are ordered, if i am not wrong, then it should be added to the material cost ?

Yes typically that is what happens however we have new tariffs that are supposed to be temporary. So since these tariffs are new and have been frequently changing as well as only being applied to goods from China, they are being charged separately. Every month we have to roll up these charges, try to match them to a customer and bill them out. We are also getting shipments from distributors which have parts from Malaysia or South Korea mixed with parts from China. Very confusing.
