It's to a separate vendor. Shipping charges for example from a freight co.

There's a po, and a series of receipts from the vendor. If you enter the receipt with a discount on the total, every subsequent receipt is handled the same way, so when you want to post the shipping, brokerage or other charges to the po, the system forces you to take a discount on these charges too, which it should not.

I'm thinking that the work-around (I hate work-arounds) is to do line-by-line discounts only - no total discount. But when you have a 500 line po with a 2% discount on the order, this is an aggravating way to enter each line.

Maybe there's a better way to do this.
