Users should be able to take cash discounts on AP documents even if the original AP document was not setup with the same amount of possible discounts. So lets say you have an existing AP Bill for $100 and you discuss the AP with the vendor and come to an agreement that you can just pay $95 to payoff the bill. You should be able to simply create a payment for $95 and take the $5 discount and allocate it to a cash discount of your choice. This will also work well for write-offs without you having to create debit adjustment and saves a lot of time and extra unneeded steps. On A/R payment receipt side, at least we have Write off reason codes. we need this or something similar to A/R reason codes on AP side.
