We have a supplier that always has a -3% discount on thier total invoice price that is not deducted in the price on the articels. This amount is not marked with a minus (-) sign before and therfore if we verify it as an exeption type it will always be coded as positive amount if we not manually put the minus sign before and it will end up in the analyse step.
And since we sometimes has difference on the amount on the articels from the supplier and what we have in our system we don't want to set the total difference on that account, because then it is not sure it always will be just the discount.

But if we just were able to use an accounting template set to -3% of the total invoice price should be coded on a specific account we would get around this trouble.
